Welcome to the Core Laboratories first-quarter 2016 earnings conference call.
(Operator Instructions)
I would now like to turn the conference over to David Demshur, Chairman, President and Chief Executive Officer. Mr. Demshur, please go ahead.
- Chairman, President and CEO
Thank you, Andrew.
I would like to say good morning in North America, good afternoon in Europe, and good evening in Asia-Pacific. We would like to welcome all of our shareholders, analysts, and most importantly, our employees to Core Laboratories' first-quarter 2016 earnings conference call. This morning, I am joined by Dick Bergmark, Core's Executive Vice President and CFO; Core's COO, Monty Davis, who will present the detailed operational review; and Chris Hill, Core's Chief Accounting Officer.
The call will be divided into five segments. Chris will start by making remarks regarding forward-looking statements. Then we'll come back and review the current macro environment, updating US and worldwide crude oil supply thoughts as related to newly calculated net decline curve rates, and then quickly comment on Core's three financial tenets which the Company employs to build long-term shareholder value. And then Chris will follow with a detailed financial overview and additional comments regarding building shareholder value.
This will be followed by Dick Bergmark commenting on Core's second quarter and second half of 2016, and our outlook, and a general industry outlook as it pertains to Core's prospects. Then Monty will go over Core's three operating segments, detailing our progress and discussing the continued successful introduction of new Core Lab technologies, and then highlighting some of Core's operations and major projects worldwide. Then we will open the phones for a Q&A session.
I'll turn it back over to Chris for remarks regarding forward-looking statements.
- CAO
Thanks, David.
Before we start the conference this morning, I will mention that some of the statements that we make during the call may include projections, estimates and other forward-looking information. This would include any discussion on the Company's business outlook.
These types of forward-looking statements are subject to a number of risks and uncertainties relating to the oil and gas industry, business conditions, international markets, international political climate and other factors including those discussed in our 1934 Act filings that may affect our outcome. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in the forward-looking statements.
We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. For a more detailed discussion of some of our foregoing risks and uncertainties, see item 1A, Risk Factors, in our annual report on Form 10-K for the fiscal year ended December 31, 2015, as well as other reports and registration statements filed by us with the SEC and the AFM.
Our comments include non-GAAP financial measures. Reconciliation to the most directly comparable GAAP financial measures is included in the press release announcing our first-quarter results. Those non-GAAP measures can also be found on our website.
With that said, I'll pass the discussion back to David.
- Chairman, President and CEO
Okay, Chris. Thank you.
Core believes that worldwide crude oil supply and demand markets will balance in the second half of 2016. On the crude oil supply side, US unconventional production peaked at 5.5 million barrels a day in March of 2015, and have since fallen by over 600,000 barrels per day, owing to high decline curve rates associated with tight oil reservoirs.
Offsetting these sharp production declines have been additions of approximately 200,000 barrels of oil per day from eight deepwater Gulf of Mexico legacy projects that were commissioned several years ago and that bared fruit in late 2015. The sharp declines from US land production are continuing in 2016, and Core believes that decreases could reach 1.1 million barrels a day by year-end 2016. Lower levels of new wells, and delayed production maintenance, will exacerbate the fall in US land production going into 2017.
Moreover, further net gains from legacy deepwater projects in the Gulf of Mexico will be needed to offset the significant decreases in existing Gulf of Mexico and its production base. These legacy deepwater Gulf of Mexico projects could add a net 200,000 barrels of oil per day in 2016, slightly offsetting the material onshore declines that are expected in 2016. Core estimates that the current net production decline curve rate for US production is approximately 10.1%, which will expand as 2016 progresses into 2017.
Globally, Core estimates that the net crude oil production decline curve has expanded to 3.3% net, up some 20 basis points from earlier estimates. Applying a 3.3% net decline curve rate to the current worldwide crude oil production base of about 85 million barrels per day means that the planet will need to produce approximately 2.8 million new barrels by this date next year to maintain current worldwide production. With long-term, worldwide spare capacity near zero, Core believes worldwide producers will not be able to offset the estimated 3.3% net production decline curve rate in 2016, leading to falling global oil production in the year.
These net decline curve rates are supported by recent IEA data indicating a decline of 300,000 barrels of production per day from February to March of 2016, which is the third consecutive month of global decline. Therefore, Core believes crude oil markets rationalize in the second half of 2016, with price stability followed by price increases returning to the energy complex. Remember: The immutable laws of physics and thermodynamics mean that the production decline curve always wins and it never sleeps.
On the demand side in the crude oil markets, the IEA is still calling for increased demand in 2016 of approximately 1.2 million barrels of oil per day, notwithstanding daily market news out of China regarding their economic activity. Recent Chinese imports, coupled with strong demand out of India, are at all-time highs. Supply and demand will balance, as they always have in past market disruptions, owing to the decline curve.
Now to review the three financial tenets by which Core used to build long shareholder value over our 20-year history of being a publicly traded company. Incidentally, Core is celebrating its 80th year on the history of innovation of technologies in the oil field in 2016.
During the first quarter, Core generated free cash flow that exceeded net income for the seventh consecutive quarter. Free cash flow for the first quarter of 2016 nearly tripled net income -- clearly, the best in the oil field service industry. Moreover, Core converted over $0.28 of every 2016 first-quarter revenue $1 into free cash flow, again, leading all oil field service companies.
Also during the first quarter, Core once again produced an industry-leading return on invested capital for the 27th consecutive quarter, topping an ROIC of 27%. Producing an industry-leading ROIC has not happened by chance.
A real-time concern for investors is the exposure of companies to the Venezuelan market. Core closed all operations in Venezuela in 2013, a discussion which at the time was highly questioned by our shareholders and potential shareholders. Departing Venezuela in 2013 led to short-term revenue and earnings growth rates that were not as robust as some other oil field service companies, for which we were criticized. This paralleled our discussion and decision to depart Mexico operations over a decade ago.
Core's internal risk assessment process determined that long-term risks clearly outweighed long-term value for the Venezuelan market. With hundreds of millions of dollars of past write-downs, and with over billions of dollars of write-downs to come, we believe that Core made the right and correct decision protecting long-term return on invested capital goals.
And finally, during the first quarter, Core returned over $23 million back to our shareholders via our quarterly dividend. The Company's outstanding share count still hovers at around an 18-year low, and the Company will be opportunistic in future share repurchases.
I will now turn it back over to Chris for a detailed financial review. Chris?
- CAO
Thanks, David.
Looking at the income statement, revenue for the first quarter was $153.6 million, so down sequentially about 16%, but that is in an environment where we have seen rig count in North America fall over 35% since December and the global rig count is down 21%. We believe for the full-year 2016, our client spending is expected to be down some 27%.
Of this revenue, service revenue is $122.8 million for the quarter, down 13.5% sequentially, but again, a favorable outcome considering the significant drop in our client spending and global rig count so far this year. Product sales revenue, which is tied more to North America, activity was lower for the quarter at $30.9 million, down about 24%, when an average horizontal rig count in the US decreased over 32% compared to the fourth quarter of 2015.
Moving on to cost of services for the quarter, they were 69.5% of revenue, up from 65.1% in the prior quarter, due primarily to the absorption of our fixed cost on lower revenues, as we continued to implement our cost-reduction initiatives throughout the quarter. Our margins on service revenue continue to be some of the strongest amongst oil field service companies. Our cost of product sales was 89.1% of revenue, up from 79.4% in the prior quarter, again due to the absorption of our fixed cost on lower revenue, and we continue to reduce our cost structure in this part of the Business.
G&A for the quarter was a little over $11 million, down from last year, primarily due to lower compensation expense. Depreciation and amortization for the quarter, $6.8 million, down sequentially from $7.1 million due to reductions in our CapEx programs starting last year.
Considering capital expenditures in 2015, and with our anticipated capital programs for this year, we would expect our quarterly depreciation expense to be about $6.8 million or lower for the remainder of the year, to total approximately $27 million for 2016. Other expense this quarter was primarily included exchange losses of $800,000.
The guidance we gave on our call for this quarter specifically excluded the impact of any FX gains or losses, so accordingly, our discussion today in pro forma EBIT and EPS exclude this foreign exchange loss. The comparisons to other quarters exclude any FX, asset impairments or employee-related severance costs that were recorded in prior periods. Excluding those FX losses to conform to our guidance, pro forma EBIT for the quarter was $23.7 million compared to $39.5 million reported last quarter, and resulting in EBIT margins of over 15%. GAAP EBIT for the first quarter was $22.9 million.
Income tax expense in this quarter was $4.4 million based on our effective tax rate of 22.5%. Net income for the quarter, ex-FX, was $15.7 million compared to $27.7 million in the fourth quarter of 2015 ex-items. GAAP net income was $15.1 million for this quarter.
Earnings per share for the quarter was $0.37 on the same basis that our guidance was given. Our GAAP EPS was $0.35 per share, which includes foreign exchange charges for this quarter, as listed on the reconciliation table to our earnings release.
As we move on to the balance sheet, and in the interest of time, I am only going to highlight the items we feel are of interest to the audience or have materially changed from previously reported balances. Cash at $16.7 million, down from $22.5 million at prior year end. Receivables stand at $122.5 million, down from $145.7 million at prior year end. Our DSOs in the quarter were 67 days, an improvement from 68 days last quarter, and comparable to the 66 days for all of 2015.
Our management team continues to focus on all important aspects running of the Business during this difficult environment. And, as Dave mentioned, I also wanted to mention that we exited our operations in Venezuela several years ago, and as a result have no receivable exposure associated with Venezuela.
Inventory at $41.7 million is up slightly from year-end balance of $40.9 million, primarily due to a few pending sales of laboratory instruments that we expect to be delivered in the second quarter. We continue to expect inventory levels to trend down as we move through 2016.
And now, on to the liability side of the balance sheet -- other current liabilities are down to $74 million from the year-end balance of $87.3 million, primarily due to the timing of accruals and payments for severance tax and other various liabilities. Our long-term debt stands at $409 million compared to $433 million at year end, so reduced about $24 million, and is comprised of $150 million in senior unsecured notes and $259 million drawn on our bank revolver credit facility.
As we stated last quarter, we have used our free cash flow in excess of the dividend to reduce the outstanding balance on the revolver this quarter. Our net debt to adjusted EBITDA for the bank covenant was 1.9 at the end of the quarter, well under the threshold of 2.5 to 1. Shareholders' equity ended the quarter at $28.3 million deficit, so up a little bit from the year-end deficit of $23.7 million, primarily due to paying dividends in excess of net income during the first quarter.
Clearly, book equity does not represent the solvency of a company, and we note that several S&P 500 companies who generate significant levels of free cash have also negative book equity because they return that free cash to their owners, just as we have done. We do not have debt or contract compliance requirements to report positive net worth.
Capital expenditures for the quarter were $2.9 million, down from the $4.5 million last quarter. The Company continues to expect that its 2016 capital expenditure program will be less than 2015, perhaps in the $12 million to $15 million range. However, if oil field activities pick up, Core has the ability to increase its investment in support of these strengthening activities.
Looking at cash flow, cash flow from operating activities in the quarter was $46.2 million, and after paying our $2.9 million in CapEx, our free cash flow is $43.3 million, an industry-leading $0.28 for every $1 of revenue earned. In the quarter, we used our cash to pay $23.3 million in dividends, and reduce our long-term debt by $24 million.
Our focus on managing the Business during this challenging environment continues to be on maximizing free cash flow and return on invested capital. Our conversion of revenue into free cash flow continues to be one of the highest in the industry at 28% for this quarter. And our free cash flow conversion ratio, which is free cash flow divided by net income, ex-FX, was over 280% for the quarter.
We believe these free cash flow metrics are important for shareholders when comparing companies' financial results, particularly for those shareholders who utilize discounted cash flow models to assess valuations. In 2015 and 2016 year to date, our free cash flow was higher than our net income, as it has been for 10 of the last 14 years.
I will now turn it over to Dick for an update on our guidance and outlook.
- EVP and CFO
Thanks, Chris.
David has discussed our industry outlook, so let's layer in our thoughts on how that may impact Core Lab. The balancing of worldwide crude oil markets continue, as evidenced by this continued sharp decline in US onshore oil production beginning in the second half of 2015. Further, the IEA estimated that worldwide demanded did increase in 2015 by 1.8 million barrels a day, and will increase an additional 1.2 million barrels per day in 2016 in response to these low commodity prices.
We believe tighter crude markets will prevail in the second half of 2016, which in turn will lead to higher energy prices and subsequent increased demand for our unique technology-related services and products. We believe the continuing decline in global production and the continuing increase in global energy consumption should create a tight crude oil supply market in the second half of 2016, which should lead first to increased crude prices, and then higher industry activity levels worldwide.
Based on typical seasonality, we project second-quarter results will decrease slightly on a sequential basis from first quarter, with revenue ranging from approximately $145 million to $150 million, yielding operating margins of approximately 14%. Our effective tax rate is expected to be approximately 14% in the second quarter, as a result of lower profitability in higher tax rate jurisdiction. Second-quarter EPS is expected to be in the $0.34 to $0.36 range, with free cash flow exceeding net income for the eighth consecutive quarter.
On an equivalent currency basis, we expect third-quarter 2016 revenue and operating income and margins to increase from second-quarter 2016 levels. Therefore, our second-quarter 2016 results should mark the bottom of our anticipated V-shape commodity recovery that should lead to increased crude oil prices followed by increased industry activity levels.
Our free cash flow as a result of earnings and continued working capital management programs will continue to be used to provide liquidity for our future quarterly dividend program, as well as debt reduction. Further, our $400 million bank revolving credit facility remains available as we continue to be, and expect to be going forward, in full compliance with terms and conditions of that facility. All operational guidance excludes any foreign currency translations, shares repurchased other than those we have already disclosed, and any further restructuring or similar expenses, and does assume an effective tax rate of 14%.
Now with that, let's turn the discussion over to Monty for an operational overview.
- COO
Thanks, Dick.
First-quarter revenues were down 16% from the fourth quarter of 2015 to $153.6 million. Operating earnings excluding foreign exchange losses were $23.7 million, yielding an operating margin of 15.4%. We thank our dedicated employees worldwide for delivering the best services and products to our clients every day.
Reservoir description revenues for the first quarter of $101.5 million were down 11.5% from the fourth quarter. Operating earnings of $18.7 million yielded operating margins of 18.4%.
The nuclear magnetic resonance group [of Flores Houston] Advanced Technology Center has designed, built, validated and commissioned proprietary reservoir condition high-frequency NMR instrumentation capable of quantifying in situ oil and water volumes in very low porosity formations. Core Lab is the only commercial laboratory offering this type of reservoir condition testing.
This new technology is currently allowing operators in the Permian and Delaware Basins to further characterize movable versus non-movable hydrocarbon in these extremely tight formations. Compilation of these core analysis data sets with detailed petrographic and sedimentology studies are assisting these west Texas operators in field completions and well-placement strategies.
In the Putumayo Basin in southwest Colombia, Core continues to evaluate fluid and core samples for enhanced oil recovery studies. Core is providing reservoir rock and fluid phase behavior data supporting our clients' secondary recovery program design.
Digital rock characterization, micro CT scanning services, Microscan, have been employed as a tool for detailed core sample assessment and selection for advanced rock properties. These samples are being used in reservoir condition flow tests that will provide greater certainty in projecting reservoir performance. Core expects additional core and fluid samples on this project during 2016.
A large NOC is currently conducting the extensive core floods on rock samples from a offshore field in the Middle East by using Core's newest state-of-the-art flow studies technology. The steady-state relative permeability live fluids recirculation system is allowing reservoir condition data sets to be acquired while using very low volumes of reservoir fluid. This ensures sufficient quantities of live fluid are available to test the large number of core samples that are required to generate a rigorously defined reservoir model.
In light of the continuous effort to optimize the efficiency of processing our field data for our customers, a further step has been made by the launch of a state-of-the-art, in-house-developed software program called [SAIL IV], which is fully integrated in our processing system, [Connect]. This will enable us to reduce a number of steps in our administrative workflow, with corresponding improvements in our cost efficiency.
Our locations around the world feed the field data into Connect, containing global, secured and validated data sets. Through authentication protocols, clients have real-time access to status information on their product flow, and more importantly, the quality data sets. The information is provided through live reports and dashboards for multiple platforms, including mobile devices such as smart phones and tablets.
Production enhancement revenues for the first quarter of $44.1 million were down 22% from Q4, compared to the North American rig count, which was down 35%. Operating earnings of $4.5 million yielded operating margins of 10.1%. Core's completion diagnostic experts and services have been called upon in the first quarter to partner with several operators to develop completion and development strategies to better navigate the current low crude oil and natural gas price environment.
Core initiated several new diagnostic projects to answer many questions about completion trade-offs. One multi-well project which has been going on from last year has determined that a new completion approach reduces completion costs by 25%, while improving production performance by 50%. These types of successes are dependent on what stage of the optimization process a company may be in, and the quality of the reservoir.
Core's customers continue to innovate ways to improve performance through the use of Core's diagnostic services. As new techniques, ideas and technologies are tested, Core's variety of diagnostic services are necessary to quickly determine which ones are successful, and to suggest new ways to overcome sub-optimal completions.
As operators continue to optimize their well-side efficiency and reservoir production, Core Laboratories' Kodiak enhanced perforating system and HERO line of perforating charges have seen increased utilization in North American shale plays. These production enhancement technologies have been successfully used by operators to increase production by as much as 15%. In the last 12 months, the HERO-PerFRAC system has experienced significant market acceptance, with a 23% increase in utilization, while the North America rig count has fallen 50% over that time.
During the first quarter, Core Lab conducted testing utilizing its state-of-the-art CT scan facilities to evaluate the HERO charge performance against other perforating technologies. The testing was conducted under simulated reservoir conditions, and revealed that the HERO patented technology achieved 15% to 40% more total depth penetration as compared to competitive charges, while leaving significantly less debris, resulting in a larger tunnel volume. Deeper penetration, minimal debris, and larger tunnel volume increases frac flow efficiency due to lower breakdown pressures and fewer screen-outs, providing operators lower stimulation cost and higher production rates.
Reservoir management earned revenue of $8 million in Q1 2016, and operating margins of 6.8%. Core continues to shift its focus to products that add value to our customers through efficiencies and cost savings, particularly as it relates to completion practices. As an example, our x-ray fluorescence and hardness testing product allows us to define rock mechanical properties using inexpensive, non-destructive core analysis techniques.
As the global merger and acquisitions market begins to pick up, Core is positioning itself as the go-to provider of strategic services. Core's leveraging off its 30-year history of conducting geological studies and collecting proprietary reservoir data to provide companies with an asset evaluation service that is unique to the industry. Strategic evaluations conducted by Core Lab have been instrumental in saving our clients tens or even hundreds of millions of dollars during acquisition, merger, and joint venture negotiations.
Outside of North America, the market for geological studies is more stable. Much of the activity is focusing on the Atlantic margin, with offshore plays in West Africa and South America dominating. Core Lab continues to see interest in our studies of these areas.
Core Lab initiated a new study of the pre-salt section off the coast of Angola in the first quarter. To date, it has been well received by the industry, and we anticipate additional subscription as the study nears completion.
Andrew, we will now open the call for questions.
Operator
We will now begin the question-and-answer session.
(Operator Instructions)
The first question comes from James West of Evercore ISI. Please go ahead.
- Analyst
Hello. Good morning, guys.
- Chairman, President and CEO
Good morning, James.
- Analyst
Dave, have you, or Monty, have you noticed any discernible changes in demand for certain products as we have gone from the back half of 2015 and saw the, another dip in oil prices in early 2016. Has there been any shift in certain product lines or certain markets or is it still -- anything for enhanced recovery?
- Chairman, President and CEO
I would say, James, from a macro view, we are seeing less demand for analysis of reservoir rock, read that being core samples. But that is being somewhat offset by an increase in the amount of fluids work that we are doing, especially fluid work revolving around increasing daily production and increasing the recovery over the life of the field. So even though it is not totally offsetting it, I would say that would be the biggest macro shift that we have seen.
- Analyst
Okay. Okay. And that is good for you. You have really no competition in fluid analysis. Is that correct?
- Chairman, President and CEO
Correct. And margins there are indeed better.
- Analyst
Right, right. Okay, great. And then a question on the second quarter guidance. It seems to me like we were exiting the first quarter at a fairly low rate in terms of at least North American rig count. Then of course, international is continuing to slide. But it looks like you are looking for much less of a sequential decline in earnings. Can you help us with that on what you are seeing in your business that may be different than what other more -- or less more commoditized product lines of companies are seeing?
- COO
A couple of things. I think we are showing a repeat of historical performance where we tend to outperform the broad metrics. So our revenue in this down cycle, yes, it has come in, but not as much as any of the rig counts that you want to use or any spending surveys that you want to use.
And I think that is a result of some of the things David just talked about. Fluids, some of the products that we have, the diagnostic services that we have that are fairly unique that create high value for the customer. So I think that is why our business has held up better than the broad markets and that is our perception for Q2 going forward as well.
- Chairman, President and CEO
And even though it is a bad house in a terrible neighborhood, the Deepwater Gulf of Mexico now is the most active Deepwater province in the world as they now out strip offshore Deepwater Brazil.
- Analyst
Right, right. Okay, great. Thanks, guys.
- Chairman, President and CEO
Okay, James.
Operator
The next question comes from Kurt Hallead of RBC. Please go ahead.
- Analyst
Good morning.
- Chairman, President and CEO
Good morning, Kurt.
- Analyst
Just wanted to get, you guys laid out the macro perspective really well, so the context of how you see the rest of the year progressing, are you getting direct indications from E&Ps that they are getting ready to get more active or are in the process of getting more active? And can they turn things around from an activity level that quickly such that you're going to have higher revenues in the third quarter? Just wanted to get a little more color around that.
- COO
Kurt, what we're thinking as the year progresses is that it will be the normal seasonal patterns. So we are not saying that there is an increase in activity yet from what we expect to be higher oil prices. That will come. What we are saying is just as the year rolls out, that we are expecting Q3 will be better than Q2 just as it has 12 out of the last 14 years.
- Analyst
Okay. And then you guys put up some very strong, well, much better than kind of industry average decrements in the Production Enhancement in the quarter. Obviously, Reservoir Description was somewhat challenged so is it my understanding that just the timing dynamic with the Reservoir Description and do you think your decrements will improve in that segment as you move forward?
- COO
Yes, Kurt, I think that is right because you look at the way we provide services in the Reservoir Description, that's the laboratory-based businesses where we are conducting experiments, tests and projects underway throughout the quarter. We are not able to effectuate a cost reduction in that group until those projects are over. So we were doing that throughout the quarter.
So we had costs that remain within that segment probably through a longer period of time in that quarter compared to Production Enhancement, where we were able to take cost out more quickly earlier in the quarter and got benefit of that as the quarter progressed.
- Chairman, President and CEO
Yes, and I think as we look towards an outlook for the third quarter, we will see margins that actually, in Reservoir Description, the decrementals may shrink to zero and we'll actually see maybe and increase, a slight increase, in operating margins, because a lot of those costs have now come out.
- Analyst
Okay. Great. And then how would you guys describe the pricing environment for your services right now?
- Chairman, President and CEO
Still pretty good. On the commodity side, where we still have some of those commodity products in Production Enhancement, essentially, those prices can't go any lower because we're kind of selling them at cost, but still on the high-tech side, margins are holding up quite well.
- Analyst
Okay. Thanks, guys. I appreciate the color.
- Chairman, President and CEO
All right, Kurt.
Operator
The next question comes from Bill Herbert of Simmons. Please go ahead.
- Analyst
Thank you. Good morning. Back to the fluid analysis and the uptake on this. I am just curious with regard to lower 48, what the client mix is in terms of the adoption of the -- and the more sort of use of the technology. Is it combined to biggest and best of breed or is it becoming broader than that right now with regard to resource holders using this technology?
- Chairman, President and CEO
Yes, Bill. Good question. The heavy users are certainly the majors and major independents, some of the more innovative companies that are out there, but we are seeing a broader reach now to some of the mid independents and smaller independents.
So, for instance, in the Deepwater Gulf of Mexico where you're running up to temperatures as high as 300 degrees Fahrenheit, 29,000 PSI. Of course those are the majors and some of the super independents like Anadarko being the users. And once you get onshore, get find the EOGs, the Pioneer Natural Resources. The Conchos are heavy users and that is now spreading to some of the smaller independents as well.
- Analyst
Okay. And then a question with regard to the macro outlook, Dave. So I am curious as to what your views are with regard to the threshold oil price and timeline required to grow US oil output significantly, call it 500,000 barrels per day or higher. So oil price timeline required to do that, please.
- Chairman, President and CEO
Actually, you must have seen my notes that we prepared.
- Analyst
Okay, that's one.
- Chairman, President and CEO
We believe that at somewhere between $65 and $75 per barrel would be the US threshold price to grow production some 500,000 barrels. Now that's going to be pushed out about six months as we retool and re-rig back up and getting crews running.
So even though we have that sustainable price for a period, you can look at a lag of maybe six more months before we start to add towards that 500,000 barrels per day of growth.
- Analyst
And finally, your views with regard to year-over-year deltas with regard to non-OPEC ex-US. Any thoughts on that with regard to magnitude of declines is what I am assuming you are looking at for 2016?
- Chairman, President and CEO
Say that again.
- Analyst
The magnitude of the production decline for non-OPEC ex-US in 2016 year-over-year assuming you are prophesying an actual decline this year.
- Chairman, President and CEO
Yes, we are. And I would say, and I will get you some better clarity on that. But that is going to be somewhere on the order of two million barrels per day in lost production.
- Analyst
Okay. That's, what I'm asking for is net, actually.
- Chairman, President and CEO
Let me get back to you on that.
- Analyst
Okay. Great. Thank you.
Operator
The next question comes from Byron Pope of Tudor Pickering Holt. Please go ahead.
- Analyst
Morning, guys. You touched in your earnings release on just how resilient some of your activity in the Deepwater Gulf has been in addition to your response to one of the prior questions and if I recall correctly, it seemed as though offshore services and products were somewhere in the ballpark of 40% of your revenue mix with Deepwater being half of that. Just given what has happened with the North American onshore landscape, could you refresh us on what that mix looks like today in terms of offshore as a percent of the total and then Deepwater within that?
- Chairman, President and CEO
Yes, 30% of all oil worldwide is produced offshore. Prior to this downturn, 40% of our revenue came from offshore. That has actually remained pretty resilient and probably now is pushing somewhere in the high-40% range for offshore and then the corresponding downturn for onshore oil worldwide has fallen from somewhere in the 60%s to probably the low 50%s.
- Analyst
Okay. And I know a lot of your reservoir fluid phase behavior work in the Gulf isn't necessarily tied to rig count activity, but do you expect that part of the business to be relatively resilient as we progress through this year?
- Chairman, President and CEO
Yes, it should be because you still have operators that are conducting a lot of tests and projects that are covered by their operating budgets and they are using the information to boost not only daily production but to make sure they increase ultimate estimated recovery from those fields.
- Analyst
Okay. That's it for me. Thanks, guys.
- Chairman, President and CEO
Thanks, Byron.
Operator
The next question comes from Chase Mulvehill of SunTrust. Please go ahead.
- Analyst
Good morning, fellows.
- Chairman, President and CEO
Good morning, Chase.
- Analyst
I guess the first question, I will kind of come back to Reservoir Description margins, they kind of came in a little bit lighter than what we had expected. So can you walk us through the main drivers for the sequential decline? Maybe as we think about mix versus pricing versus the cost burden that you mentioned?
- EVP and CFO
Yes, when you think about the sequential change, we have talked about our cost structure a tad, so we believe those costs are coming out, so that will be an improvement. On the higher tech services, they're more proprietary in nature. Dave has already talked about pricing on those reasonable.
But on the commodities, services and products, we talked about how there is pressure on those. You throw all of that in the mix, that is part of the reason why we have got the sequential decline. So it is a little of that and a little bit of just activity levels are down. If you look at the average rig count in Q2, it will be lower than the average rig count in Q1.
- Analyst
Right. Okay. I was trying to, I caught some of the commentary around the margin profile for Reservoir Description. Was that commentary around 2Q or 3Q when you were talking potentially zero decrementals?
- Chairman, President and CEO
Yes, that was going in -- that would be Q3, Chase. So we would see the bottom and -- or decrementals may be crossing over to incrementals in the third quarter release.
- Analyst
Okay. And so as we look at 2Q margins for Reservoir Description, care to take a stab at what you think they might be?
- Chairman, President and CEO
Monty?
- COO
They will be, in the Reservoir Description in particular, they will be around 20%. I think a little better than what we had in the first quarter and that is due to the way the cost structure is being handled, reductions there. So reservoir is that what you're asking? Just Reservoir Description?
- Analyst
Yes. Just Reservoir Description.
- COO
We should have been plus or minus 20%, a little better.
- Analyst
Okay. And then for 2016 Reservoir Description revenues, any sense about order of magnitude, if they'll be down?
- Chairman, President and CEO
It just depends on the second half. That's a hard one, Chase.
- Analyst
Should we think about international CapEx, global CapEx, what's the -- if we're thinking about modeling this, how should we think about it?
- Chairman, President and CEO
I'm thinking you are going to have to have heavy reliance on what you think international CapEx and spending and activity levels will be because we don't see a substantial increase in North America until going into 2017.
- Analyst
Right. Okay.
- EVP and CFO
And operating budgets, too, as well, Chase. Don't forget that. It's not totally projects.
- Analyst
Absolutely. Okay. I'm going to shift gears real quickly. And so, bear with me on this hypothetical, but let's assume that things don't rebound in the second half and you need to get coveted relief to a max leverage ratio of three times. Can you talk about the dividend and whether it is safe under this scenario?
- EVP and CFO
We believe it is safe under the current scenario and it would be even more safe under the scenario you just mentioned if we increased that debt to EBITDA ratio with the bank.
- Analyst
Okay. All right. That's all I have. I will turn it back over.
- Chairman, President and CEO
Okay, Chase.
- Analyst
Thanks, Dave. Thanks, Dick.
Operator
The next question comes from Blake Hutchinson of Howard Weil. Please go ahead.
- Analyst
I want to attack maybe that back half progression or Reservoir Description top line a little bit differently and maybe David you could help us out with a bit of a history lesson. I guess as we started this year, I think the business got hit a little bit more by kind of deferred maintenance, maybe some major field project shutdowns.
I mean, have you typically, I guess in terms of reactivity of top line of Reservoir Description, do we simply need to think about that being the long-lead investor or are there buckets of it that you would argue get turned on more quickly given their production nature, production-related nature and maybe can you talk about those buckets for us?
- Chairman, President and CEO
Yes, on the international side, we have seen some decrease but actually, those are a lot longer-term projects. The majority of the impact in Reservoir Description was North America and land. So, projects owing to tight oil and then just some pressure maintenance projects or some EOR for conventional fields onshore.
- Analyst
Okay so maybe going back to the reset that you did Deepwater for us. I mean you usually talk about kind of 70%/30% or 75%/25% international/domestic for that business. Have we reached extremes on that? Are we 80%/20%, 90%/10%?
- EVP and CFO
I would say we are probably pushing a little bit over 80% and a little less 20% North America.
- Analyst
Got you. Thanks. And then just a point of clarification on the Production Enhancement margins, maybe for Dick. I guess we should take away that you feel like you attacked a cost structure, as you noted in the release, early, and so were comfortable with the levels that were achieved in 1Q. There was not necessarily an additive, a mix additive or a Gulf of Mexico additive that helped that and so we kind of keep the progress we made on that cost structure as we head into Q2.
- EVP and CFO
There were not one-off items, so you're right. It was a normal flow given this environment, but we do think margins. Monty talked about 20% margins for Reservoir Description, perhaps Production Enhancement is low single digits, but not negative.
- Analyst
Okay. I appreciate that. I will turn it back. Thank you.
- Chairman, President and CEO
All right, Blake.
Operator
The next question comes from Rob MacKenzie of IBERIA Capital. Please go ahead.
- Analyst
Thanks. The question I guess for you, Dave, with the seemingly pickup in the number of E&Ps transacting properties and properties changing hands, including the number of private equity shops, how much of an opportunity would that represent to you in terms of being able to characterize and help the buyer of some of these properties understand what they're buying?
- Chairman, President and CEO
I will let Monty make some comments because in reservoir management, we are seeing more private equity folks than we have seen in quite a while and explore those data sets. Monty?
- COO
Yes, we have a dedicated effort to helping not only the private equity but anyone that's assessing properties as to what they might be looking at, what might be a good deal, and what might not be a good deal. We have a vast knowledge, as you know, through our studies, of plays all over North America and the international arena.
More of the activity is probably going to be in North America. And we have got a pretty good handle on what you can expect to produce and then, of course, they have to run their models on what they think the price they're going to sell that for. But we can tell them what the best plays are and then they've got to decide the valuations. But we've got a dedicated effort and we are working with people on that now.
- Chairman, President and CEO
And Rob, actually, adding to that, we are doing a lot of major proprietary in-house work, trying to evaluate acreage as we mentioned in the release. We just finished up our largest proprietary project and this was essentially looking at drilling locations going forward in this pricing environment.
Not only are we seeing private equity, but also some of our clients looking to use a microscope to find where those best drilling locations will be where they can find the highest production rates, greatest return on their invested capital.
- Analyst
Okay. Thanks. I guess, I was also hoping to get a little bit of a feel for how material some of that might be to you all.
- COO
At the current time, I would not say it is material. It could build to material. But there has not been that much activity in acquisitions at this point in time. We keep expecting it to pick up soon, but that is hard to say. Everybody is being a little bit cautious.
- Analyst
Got it. Okay. And in terms of picking up, I wanted to try and dig a little bit deeper on some of that and where you expect to see the uptick come first. Obviously, I would think it would be more North American related versus international and correct me if that's correct, but would you expect to see it kind of concurrently in terms of Reservoir Description characterizing rocks and fluids along with the completion side of Production Enhancement or would you expect Production Enhancement to be the first to show signs of recovery?
- Chairman, President and CEO
Usually the canary in the coal mine is the Reservoir Description group. So we would see the delta take place because we have not had that much of a down shift internationally. That would have to be North America to where we would see the delta on the uptick. And it could happen commensurately with Production Enhancement as you get either re-completions, re-fracs or the completion of some of the ducts.
- Analyst
Great. And have you seen any signs of the duct inventory starting to be drawn down yet, Dave?
- Chairman, President and CEO
Yes, I would say that is not a material number at this point, but actually, the duct count, let's just say that background ducts is about 1,500, and right now, there is probably a little over 4,000. We are starting to see that get chiseled away.
- Analyst
Okay. Thanks very much.
- Chairman, President and CEO
Okay, Rob.
Operator
The next question comes from Igor Levi of Morgan Stanley. Please go ahead.
- Analyst
Good morning, guys. Great job navigating the worst quarter we have seen in a long time, especially on free cash flow. Could you talk a bit about what you've seen in market share trends for various products and service lines that you have over the course of this downturn?
I mean, how many of the 2,000 fields that you're targeting reservoir description are you on now and are more oil companies now in-sourcing work or outsourcing work to Core Labs? And then similarly, on the Production Enhancement segment, what are market share trends like in North America and international?
- Chairman, President and CEO
Igor, couple of good questions, actually. If you look at Reservoir Description, the last count we had as we were active on about 1,250 fields, we still have commitments to do work in those fields, although some of that workflow may have slowed down or been postponed for a period of time.
On more of an acute side, before we leave Reservoir Description, yes, we are seeing some of the majors do more of their work in-house because they are at lower levels of work. So we see market share anywhere, it could be back to our best clients. So we look for that to return back to status when activities pick up.
- EVP and CFO
That being said, Igor, we did put in the release a project that we are doing in South America for a major IOC that clearly has in-house capabilities, but it is just technology that we have that's more applicable to what they are trying to do. So, it is hard to say they're trends. It is kind of going both ways.
- Chairman, President and CEO
Yes. That's a good point, Dick. And then on more of an acute side for Production Enhancement, because we don't share a lot of those technologies or other oil field service companies don't offer a lot of those technologies, I would not say that share has slid in just the sheer volume of number of wells that have been drilled or not drilled has really affected their revenue and profitability.
- Analyst
Great. That is very helpful. And just one question on the new technology side. In the second quarter of last year, you talked about the new recirculation system focusing on P&A work in the North Sea and then you mentioned that again in last night's release, seeing increased acceptance.
I was hoping you could talk a bit more about the acceptance of this technology, the type of share gains perhaps you are seeing and has this actually driven an increase in TNA work since we know a lot of that has been delayed during the course of the downturn?
- COO
What we have done, Igor, is it's say much more efficient from a cost standpoint and a time standpoint system. So what we are doing is helping them make it less costly and more timely. I would be hard-pressed to say that's going to make them to plug and abandon faster in this environment, but having said that, we are definitely doing more of that type of work.
We have seen that product grow continually over the last year since we introduced it and it is a very easy sell on the value add to the client. So where they are going to do plug and abandonment, we have a great system that they are adapting to very quickly. So that has been growing. That's been a growing segment as are several of the technologies I mentioned in my previous discussion points. Where there is technology that benefits the client, it's growing.
- Analyst
Great. And then finally, this is the first quarter where we haven't seen share buybacks in a long time, where you're using the excess free cash flow after the dividend to pay down debt. Now your leverage ratio is over half a turn within the covenant. So what is the level that you guys, could you just remind us, are comfortable with and when -- could we expect you to return back to the market to buy back shares before the end of the year?
- EVP and CFO
What we are doing right now is behaving similar to what we did in 2008, 2009 where we actually backed in, put cash on the balance sheet, because we just were not certain with great clarity when the market would improve. So we have a view that the market is improving and will continue to improve, but we, in the interim periods, will probably use our excess free cash beyond the on the dividend to repay our revolver debt.
That way, we take the question of that debt to EBITDA off the table because it does not come into play as we pay down debt and we will continue to pay the dividend. And so right now, that is our capital allocation is dividend first, pay down debt. Stock buybacks however continue to be viewed as an opportunistic allocation of capital.
So we are not saying we have suspended the program. We've just said currently, we're going to pay the dividend and pay down debt.
- Analyst
Great. Thank you very much. I will turn it back.
Operator
The next question comes from Matt Marietta of Stephens. Please go ahead.
- Analyst
Solid quarter. Obviously, the guidance and outlook much more stable than I think many of the other companies we all cover in oil field services, so congratulations on that. When we look at V bottom, can you help us maybe understand what the upward slope of the V may look like from kind of a rig count oil price, and then ultimately, production perspective? The down slope of the V has been very steep, very long.
But obviously, there is going to be a lot of constraints to re-ramp production given the deep cuts that have occurred primarily in North America. I am just hoping to maybe get some color into how this V or the upwards slope of this V unfolds in your crystal ball with respect to domestic international rig counts, spending levels, activity and maybe offer you an opportunity to hedge a little bit here on what, in this outlook, if there is anything that can derail the outlook of a V-shaped kind of recovery as we head into the back half of the year.
- Chairman, President and CEO
Yes, Matt. I think that the slope of that upward V is going to be directly related to the slope of the upward V on the price of the energy complex, for North America, certainly, natural gas and crude oil. That is where we are going to have the biggest delta in activity levels take place in response to those higher oil prices.
I think the earlier question on what kind of price we need to really start building back production gains in the US was somewhere between $65 and $75 a barrel. So as quick as you can ramp to that level it's probably will determine the upslope of the V-shape.
Internationally, yes, activity levels have been down, but not anywhere near as sharply as they had been in North America. So really the controlling factor on the upside is going to be the price of crude and the response in activity levels in North America. Other than that, I don't think we can get more granular.
- Analyst
I guess a lot of the focus is in US production and activity, but in light of the failed meetings really in recently in Doha and the rhetoric from Russia and Saudi that they can increase their output. There is obviously challenges ongoing in Libya and other places in North Africa, but how do you think about the potential for further production increases out of OPEC and other major players?
Are they possible from here? And what could that possibly due to the V-shape recovery? I guess what I'm after is what about the other 90% of the oil market outside of US? What are those net declines going to look like in the back half of the year and what do we think demand is going to be in the back half of the year to help us kind of calibrate how to think about the V bottom?
- Chairman, President and CEO
Yes, but right now, our suggestion is that our net worldwide decline curve rate is going to be 3.3%. When we look at OPEC and really globally, we don't see a lot of sustainable spare capacity. You may have some producers in the Middle East that could sharply raise crude production for a short period of time, but on a sustainable rate, it probably cannot occur.
So because of the lack of spare capacity worldwide, we don't think any crude comes on the market unexpectedly due to just raising current production rates. That is probably not going to happen. So what could not delay the back end of that is you have peace that breaks out everywhere and you get Libyan production back and those that are off the market because of political turmoil.
We really see that not happening either. So that is based on our 3.3% net global decline curve rate. We've plugged that into recovery of the commodity markets in the second half of 2016. I hope that helps.
- Analyst
It does. And on the demand side, are we kind of sticking to the IEA (multiple speakers)?
- Chairman, President and CEO
Yes, we are not demand guys so we just, that's why we always use the IEA number, because you guys are far better on demand than we are and we're supply side guys.
- Analyst
Thanks a lot for the color. I appreciate that.
- Chairman, President and CEO
Very good, Matt.
Operator
Sir, will there be time for any further questions today?
- Chairman, President and CEO
We will take two more questions.
Operator
Okay, first we have Darren Gacicia of KLR Group. Please go ahead.
- Analyst
Thank you for squeezing me in. I have been writing the last couple months about non-OPEC rig counts being down. Now, it looks like it's going to closer to 40%. And thinking about that having an impact on production, that does not seem to be in IEA numbers. Today, you have increased your decline rate forecast to 3.3% from 3.1%. Last quarter, you did it up from 2.5%.
- Chairman, President and CEO
Correct.
- Analyst
What I really wanted to get to is what are the drivers of bringing that up? Is it looking at what is happening with rig counts? Is there other things that you think are happening with the way people are managing reservoirs that are changing the decline rates? Is it just maintenance expenditure alone? Can you talk to a little bit about the componentry of what leads you to up that decline rate?
- Chairman, President and CEO
Yes, I think you, Darren, I think you touched on all three of them. Certainly, the lack of new drilling and fresh production coming on. Probably then followed closely by the lack of production maintenance projects undergoing. And then, thirdly, the delay in the start of enhanced oil recovery projects that are needed to bolster that. So you add those three together.
I think, still, the biggest component is the drill bit and then followed by lack of maintenance CapEx and then delays on enhanced oil recovery projects. So you add those into the mix and that's why we have upped it from 2.5% to 3.1%, now to 3.3%.
- Analyst
Do you think that, since international activity is bound to recover at a bigger lag given the budgeting cycles, North America, we have been batting it around on the calls, a little bit of a wild card in terms of how quickly that comes back depending on price recovery. Does the propensity of that 3.3% have the potential to continue to go higher the longer the activity stays at depressed levels?
I'm just trying to get a sense because we seem to be on a revision track here. Can we kind of expect to continue to decline according to what your thoughts are?
- Chairman, President and CEO
Yes. At current activity levels, absolutely, positively, that will continue to increase.
- Analyst
Does that inherently imply that the IEA numbers for national productions probably need to come down?
- Chairman, President and CEO
Our prediction is that they will come down.
- Analyst
Got you. Well thanks for the help. I appreciate it.
- Chairman, President and CEO
Okay, Darren.
Operator
And the last question will come from Brandon Dobell, William Blair. Please go ahead.
- Analyst
Thanks for squeezing me in as well.
- Chairman, President and CEO
Hello, Brandon.
- Analyst
Maybe some color on how you guys think about stage count per well dynamics. I know there's a general trend, obviously up. Do you think that trend is stalled given spending constraints? At a higher oil price, do you see stage count per well accelerating, kind of maintaining the same trajectory? Just trying to get a feel for how that curve may look in a recovery scenario for oil prices.
- Chairman, President and CEO
We still think they increase. You have some fairly sophisticated operators that are now drilling 12,000 foot laterals and using 60 stages. We talked to this two and three years ago to the amazement of folks. And so, we still feel see that continuing and so longer laterals, more stages, higher degrees of profit. That is the recipe for success.
- Analyst
Does the spending constraints of last year or so, has it caused people to take a slower path up on trying towards some of those leading-edge producers are in terms of stage count dynamics? I mean they kind of say, you know what, we'll stick here for a while and then things get better, we'll accelerate to where those leading-edge guys are or is it a still pretty steady increase overall?
- Chairman, President and CEO
No, I think you're right on. That has certainly slowed the innovation on completion and completion in design and that entails the longer laterals and the more stages.
- Analyst
Okay. All right. Thanks, guys. I appreciate it.
- Chairman, President and CEO
Thanks, Brandon.
Operator
This concludes our question-and-answer session. I would like to turn the conference back over to David Demshur for any closing remarks.
- Chairman, President and CEO
Thanks, Andrew. So in summary, Core's operations continue to position the Company for slightly lower activity levels in Q2 and we know that significant challenges await. However, we have never been better positioned operational and technologically to help our clients maintain and expand their existing production base. We remain uniquely focused and are the most technologically advanced reservoir optimization company in the oil field service sector.
This positions Core well for the challenges ahead in 2016 and into 2017. The Company remains committed to industry-leading levels of free cash generation, returns on invested capital, with excess capital being returned to our shareholder via dividends and possible opportunistic share repurchases.
In closing, we would like to thank all of our shareholders and the analysts that follow Core and as already mentioned by Monty Davis, the Executive Management and Board of Core Laboratories give special thanks to our worldwide employees that have made our results possible. We are proud to be associated with our continued achievements. So thanks for spending your morning with us and we look forward to our next update. Goodbye for now.
