Oil Rig Count Falls By 1 As Analyst Warns Permian Reserves Are Grossly Exaggerated

For only the second time in the last 27 weeks (and 4th in the last 56 weeks), the number of US oil rigs fell last week (down 1 to 764 rigs). There is a growing concern that the rising rig count has now outpaced the lagged response to pricing and is due to rollover further...



Notably the Canadian oil rig count rose by 12 last week.


WTI tumbled to a $45 handle heading into the data after tanker-tracker data suggested OPEC supply was the highest in 2017...



“To really see the market push much higher, we need to see a drumbeat that inventory levels are being pared like the main producers who are cutting production say is happening,” Gene McGillian, market research manager at Tradition Energy in Stamford, Conn., says by phone to Bloomberg. Without that “further gains are going to be kind of tough to come by.”


As a reminder, after rebounding last week, it looks like the Alaskan component of US oil production slowed this week as maintenance work continues in the Alaskan North Slope, but the Lower 48 saw production hit 2 year highs...




And if the government is to be believed that is great news for "Murica...





We are entering a new age of American energy dominance according to Energy Secretary Rick Perry.



President Trump reflected that view in comments he made last week that “…we’ve got underneath us more oil than anybody, and nobody knew it until five years ago.”



Trump was referring to tight oil production and today, that means the Permian basin.



But as OilPrice.com"s Arthur Berman notes, global energy dominance by the United States is somewhere between aspirational and absurd.


So far in 2017, the U.S. has imported more than 9 million barrels of crude oil per day, and net imports have averaged more than 7.3 million barrels per day. How exactly can the world’s biggest importer of oil become the supplier upon which other countries depend?


The recently released BP Statistical Review Of World Energy 2017 places the United States 10th in the global ranking of oil reserve holders between Libya and Nigeria (Figure 1). That’s not bad but it hardly puts the U.S. in the same league as energy-dominant countries like Venezuela, Saudi Arabia, Canada, Iran, Iraq and Russia that have on average 4 times more proved reserves than the U.S.

Perhaps the President and Secretary Perry have been reading John Mauldin’s recent work of magical realism Shale Oil: Another Layer of US Power. It features a chart which shows that the U.S. is the largest oil reserve holder in the world (Figure 2)

The chart is so wrong that it defies explanation.


Its Rystad Energy source data reveals that Mauldin has misrepresented recoverable resources—all oil regardless of commercial value–as reserves—a specific volume that is commercial at today’s oil prices.


It also seems that Mauldin didn’t show Rystad’s data correctly. Saudi Arabia—and not the U.S.—is the largest holder of recoverable resources according to Rystad (Figure 3).

Rystad’s P1 proved and P2 proved-plus-probable reserve estimates put the U.S. behind Saudi Arabia, Russia and Iran.


There are many other errors in Mauldin’s transcription of Rystad’s data that can be seen by comparing his chart as my Figure 2 with Rystad’s data in my Figure 3. That’s what happens when energy amateurs masquerade as energy experts.


Assessing the Growth Potential of the Permian Basin


So much for U.S. energy dominance today but what about the growth potential of the Permian basin?


Pioneer Natural Resources CEO Scott Sheffield claims that output may exceed 160 billion barrels of oil. Even credible sources like Wood Mackenzie believe that Permian Wolfcamp growth alone will add 3 million barrels per day by 2024.


The EIA, however, estimated that 2015 Permian tight oil reserves were only 782 million barrels (Table 1). That seems low and is considerably less than the 5 billion and 4.3 billion barrels attributed to the Bakken and Eagle Ford plays, respectively.

I estimate that there are approximately 3.7 billion barrels of proved Permian tight oil reserves using 2016 10-K SEC filings for leading operators in the plays (Table 2).

All the companies in Table 2 differentiated Permian reserves from other company reserves. Those companies accounted for 47% of all tight oil production in 2016. I used that as a scaling factor to estimate the contribution of companies such as Anadarko, Apache, EOG and OXY that did not separate Permian from other company reserves in their 10-K filings.


The estimate is grounded on a reliable base of 1.7 billion barrels from company filings. The assumption that unknown company reserves will follow 2016 production ratios is reasonable but uncertain.


I imagine that an estimate of only 3.7 billion barrels may surprise many who buy into the vision of American energy dominance. Others may accept the estimate but argue that Permian plays have significant growth potential that the Bakken and Eagle Ford do not.


Concho and Pioneer included tables in their 2016 10-Ks that projected future production from proven undeveloped (PUD) reserves. That data indicates that the two leading producers in the Permian tight oil plays anticipate PUD production to peak in 2019 (Figure 4).

Concho’s and Pioneer’s combined peak 2019 PUD production volumes are approximately 25% of their combined 2016 daily production from the Permian basin. That means that the addition of future PUD production may only offset legacy production decline rates.



Anticipated PUD volumes are already included as proved reserves so however we view this data, it does not affect the implied reserves for the Permian basin. 10-K reserve and PUD production forecasts are based on 2016 SEC oil and gas prices. Higher prices would mean higher reserves and PUD production although few now anticipate substantial price changes over the period covered by Concho’s and Pioneer’s estimates.


Tank Theory


Permian tight oil reserves implied by this study are less than accepted estimates for the Bakken and Eagle Ford plays. Permian production, however, has already reached peak Eagle Ford levels and is still increasing (Figure 5).

To many, this implies that Permian production will continue to increase and will eventually eclipse output from the older tight oil plays. That may be true but, without additional reserves from new plays or deeper layers, it may only reflect rate acceleration followed by steep decline once peak production is reached. Concho’s and Pioneer’s future production forecast suggests that peak production may occur sooner than later.


This study represents one scenario that may provide context for the claims and expectations about future production potential for the Permian basin.  Aside from weak growth in the offshore Gulf of Mexico, or some return to growth in the Bakken and Eagle Ford plays, it is the only current basis for the crude oil portion of emerging American energy dominance.


For the U.S. to move into the top tier of oil producing countries, reserves must at least double from accepted estimates by BP, EIA and other credible organizations (Figure 6).

In some upside scenario in which Permian reserves of 3.7 billion barrels somehow double or triple, that still will not be nearly enough for the U.S. to become energy dominant in oil.


Engineers commonly think of reserves as a tank - you can drain the tank with the best technology at very high rates, and perhaps make some money along the way, but ultimate production is limited by the size of the tank.


I have presented an estimate of tank size using as a basis data from the companies that know most about the plays. If it is even close to correct, American energy dominance should be recognized as just another expression of alternative facts.

As if more confirmation was needed...the Permian basin has been leading the increase in horizontal oil rig count (+184%)



But, the horizontal oil rig count changes from May 2016 by producers" sources of funding shows that junk bond funded rigs have plateaued!

Shale Efficiency Has Peaked For Now As Rig Count Surges For 22nd Straight Week

For the 22nd week in a row, the number of US oil rigs rose (up 6 to 747) to the highest since April 2015.


Given the historical relationship between lagged prices and rig counts, we suspect the resurgence in rigs may begin to stall...



Oil is headed for the longest run of weekly losses since August 2015 as OPEC member Libya restored production and the surplus in the U.S. shows little sign of abating.





"Inventory levels remain stubbornly high," said Bill O’Grady, chief market strategist at Confluence Investment Management in St. Louis.



"The reality is, the things that have caused this trading range remain in place. Nothing’s changed."



US Crude Production from the Lower 48 rebounded this week (after a modest fall the week before) to new cycle highs...




The growth in rigs has been almost entirely in The Permian...



But, as Reuters reports, while cash, people and equipment are pouring into the prolific Permian shale basin in Texas as business booms in the largest U.S. oilfield, one group of investors is heading the other way - concerned that shale may become a victim of its own success.





Eight prominent hedge funds have reduced the size of their positions in ten of the top shale firms by over $400 million, concerned producers are pumping oil so fast they will undo the nascent recovery in the industry after OPEC and some non-OPEC producers agreed to cut supply in November.



The funds, with assets of $286 billion and substantial energy holdings, cut exposure to firms that are either pure-play Permian companies or that derive significant revenues from the region, according to an analysis of their investments based on Reuters data.



"Margins will continue to be squeezed by a 15 to 20 percent increase in service costs in the Permian basin," said Michael Roomberg, portfolio manager of the Miller/Howard Drill Bit to Burner Tip Fund.



Which, despite the forecasts for increasing production, fits with OilPrice.com"s Peter Tertzakian warning that shale efficiency has peaked... for now.


Learning takes time and effort. But a good education pays off.


North America’s oil industry has been in school for the past three years, studying how to become more productive in a fragile $50-a-barrel world. Many companies in the class of 2017 have graduated and are now competing hard for a greater share of global barrels.


Having said that, North America’s education on how to make oilfields more productive appears to be stalling. After a breathtaking uphill sprint, productivity data from the U.S. Energy Information Agency (EIA) shows that the last few thousand oil wells in top-class American plays may have hit a limit—at least for now.


Our Figure this week shows a classic S-curve learning pattern in the mother lode of all oil plays: the Permian Basin. Slow improvements to rig productivity (2012 to 2015) were followed by a steep period of rapid learning (2015 to 2017). Eventually limitations set in and advancement quickly stalled upon mastering new processes (2017 to the present).

As with many things in life it’s repetition that leads to mastery. Getting to know the rocks better and using progressively better techniques to extract the hydrocarbons facilitate learning in the oil and gas business. Each subsequent well that’s drilled yields a better understanding on how to drill and extract the oil buried several kilometers beneath a prospector’s feet. Trial, error and breakthroughs through repetitive drilling have been a longstanding hallmark of this 150-year-old business.


The “light tight oil” (LTO) revolution began in North America circa 2010. It took about 30,000 wells and three years before the learning in the Permian Basin kicked in. The next 20,000 wells yielded an impressive doubling of productivity. But it was innovation from the following 10,000 wells when mastery set in; by the time the 60 thousandth well was drilled the amount of new oil produced by a single drilling rig (averaged over a month) more than tripled to 700 B/d.


Aside from learning more about the rocks, the following six factors have contributed to the tight oil learning curve:





1. Walking rigs – Assembling and dismantling rigs for each new well used to be an unproductive, time consuming process. Wrenches and bolts are passé; new rigs “walk” on large well pads needling holes in the ground like a sewing machine on a patch.



2. Bigger, better gear – From drill bits to motors, pump and electronic sensors, all the gear on a rig is now more powerful and more precise.



3. Longer lateral wells – A horizontal well is like a trough that gathers oil in the rock formation. Why stop at one kilometer when you can drill out two or three with the better gear?



4. Fracturing with greater intensity – Hydraulic fracturing used to be a one-off, complicated process. Today, liberating tight oil is like unzipping a zipper down the length of a lateral well section.



5. Smarter, better logistics – Idle time on well sites can cost tens of thousands of dollars an hour. Modern supply chain management and logistics are helping operators use every hour of the clock more cost effectively.



6. ‘High grading’ of prospects – Low oil prices culled the industry’s spreadsheets of uneconomic play areas. Activity migrated to high quality ‘sweet spots’, which are turning out to be more plentiful than originally thought.



How much better can it all get? 


The data in our chart, and from other plays, suggests that the collective learning from these factors may have peaked; ergo a high school conclusion might lead us to believe that the golden geese—tight oil wells drilled into prolific plays like the US Permian and Eagle Ford—may have finally finished laying bigger and bigger eggs.


But it’s not wise to be fooled into that sort of undergraduate thinking. Productivity may have stalled for now, but the learning is paying off. The rate of output growth in the new genre of light tight oil plays isn’t about to lose momentum around the $50/B mark.


Learning is infectious. And what good student starts from the proverbial “square one?” Only fools reinvent the wheel. Knowledge gained from American “tight oil” plays is spreading to other plays and has already spread north into Canada where conditions favour copycat learning. Plays like the Montney and Duvernay are already climbing up their learning curves.


All this learning sounds like bad news for oversupplied oil markets. Yet there is a flip side: The good news for North America is that not everyone is going to the same school. Those on the other side of the world aren’t drilling thousands of wells from which they can learn. They’re relying on OPEC valve closures to save their competitiveness in the old-school way of doing things.


The irony is that OPEC’s artificially supported oil price is tuition for North America’s industry. On their tab we’re learning how to produce more oil at lower prices.
