"One of the biggest potential advances in shale production could come from increasing the recovery rate. The recovery percentage of shale oil in the U.S. typically ranges from about 5% to 15% of the original oil in place, depending on the specific technology and formation characteristics."
The CEO of Chevron recently emphasized that the next phase of the shale revolution is to increase the recovery rate. Every 1%-point increase in the recovery rate is worth billions and according to Chevron: “We know where the oil is. If we left 90% of the oil behind, it would be the first time in history that we didn't figure out how to do it”.

This new campaign for the tight oil sector is brilliant. It cannot lose with this new propaganda program, be in coke proppant (Exxon), more soap in the frac fluid (Chevron), new technological advances (everybody).

Facts on AI

We need to face facts. We do not have enough nat gas to power AI. We need that gas for home heating and industrial heating. Nuclear energy is all effed up. As for renewables, they are a joke. The only way to power AI and replace nat gas power plants is with coal. If we want to re-industrialize we need to revive the coal industry. We have plenty of coal; we just need to get past the climate change hysteria and start using it.

When we're "spoilt for choice" for energy sources, coal gets pushed aside in favor of sources that are supposedly easier on the environment. And it loses vs cheap natural gas all the time. But, if it's really greenhouse gas we're afraid of, I can't find anyone who will give me a comparison between the short term impact of burning methane, which supposedly puts way more GHG into circulation short term, compared to burning coal, which has way more energy but also puts more CO2 into the environment but over the longer haul. Since most people seem to only focus on the next few months or maybe years, that seems relevant. Bottom line, my personal opinion is that price will decide. When, not if, nat gas prices ramp to double digits in this country again we'll see a lot of fans show up for coal. The dirty little secret of the data centers is that even the ones who talk about being "net zero" use diesel to back up their renewable power supply.

A Statement So Applicable to My Industry...
A Statement So Applicable to My Industry...

ree

Bloomberg recently wrote that most U.S. tight oil wells now decline 90% the first 36 months of production life.


Above is the most recent production profile I can produce for wells drilled in 2022 that are 3 years old in the Permian HZ tight oil play. They, in fact, declined 89.6% in three years. These are all wells, both sub-basins, all benches drilled in 2022. This is a Novi chart, by the way, created using realized production data from the Texas Railroad Commission.


Please note that ensuing years, 2023, 2024 and those wells drilled to July 2025 on an oil rate in BOPD vs. time are less productive than 2022 wells so it is likely that, at least in the Permian, wells now decline more than 90% the first 36 months of production life.


I think you need to seriously let that sink in a minute. Imagine investing $10MM, risking…

Mike,


It may be that part of the attraction to tight oil is a quick return on investment, at least in theory. An ideal well would produce all of its EUR as quickly as possible and a well that declines very quickly comes closest to this ideal, producing about 73% of EUR in the first 5 years of operation (2020 average Permian well). The average 2020 Permian well produced about 331.5 kbo in its first 60 months, so for a $10 million dollar well if the operator nets $30.17/bo produced the well would have paid out D&C costs after 60 months. The ROI would be terrible however at under 33% over the life of the well and under 2%/year ROI. A net of $60/bo gets a decent return which would require about $90/b or more at the well head.


As you have said for a long time this does not work well at low price levels.


At some point the rig counts and wells completed will head south.

The Latest Goehring & Rozencwajg Commentary (Q325)

As is usual, the entire commentary is valuable and worth reading (download at their website). Here are a few relevant bits (the rest that follows it G&R's writing, not mine):


+++++++

The Permian Rolled Over

First, U.S. shale oil production turned negative year-on-year in October. We first forecast this outcome back in 2019, arguing that shale output would begin to roll over around 2026.


We later pulled that estimate forward to 2025—and events now suggest that call was on target. Several years ago, well before today’s AI enthusiasm, we built a deep-neural-network model to parse the drivers of shale productivity. That work proved invaluable.


The model made clear that most of the productivity gains the industry celebrated were not the result of breakthrough drilling techniques, but rather of something far more prosaic: high-grading. Companies were drilling their best remaining locations first.

For tight oil my 80% confidence interval for URR is 75 to 95 Gb, chart below is the low price scenario where it is assumed the current low oil prices persist over the long term.

More On Associated Gas as LNG Food


ree

Here is a recent Rystad graphic showing type decline for Midland Basin HZ tight oil wells to 3 years. In gas depletion, oil expansion driven mudstones (shale) everything poops out eventually. It depletes, even associated gas from oil wells. See above.


I had C+C declining at the rate of 83-85% in the first 32 months of production, Rystad says 90% in three years. Try and get your head wrapped around that.


Longer laterals are hiding pressure depletion...don't be fooled by that. It cannot last much longer and when it doesn't, U.S. production will fall fast.


EUR's have fallen in the Midland Basin to 385-400K BO and 2.1-2.4 BCF gas.

I think I can answer that. I found from and EIA report that Alpine High has the following TRR: 11.5 billion barrels of oil, 35.1 billion barrels of NGL and 27 trillion cu ft of natural gas. BTW, the EUR for a well is 1.11 million barrels. I've heard you speak with some disparagement of Alpine High. EIA is a very reputable source. Is this possibly true? If they are way off here, how much are they off in other areas of the Permian?

Nat Gas price

Natural gas is now $5, the first time it has reached that level in 3 years. A cold winter and strong LNG demand are pushing it up. God help anyone trying to heat their home this winter without a strong bank account. I think it might go to $10. That's where Europe is.

Over-Drilling

ree

Thad was, is a no bullshit PE that nobody could buy, sort of like Scott Lapierre. This chart is self-explanatory but briefly, the closer together they (EOG?) drilled Wolfcamp A wells in Lea County, the worse they got. Parent/child interference has only become worse since this chart was produced 7 years ago.

A former oil company CEO told me that his company found that 1320 foot spacing in the Delaware Basin was optimal, different companies may have reached different conclusions and this probably depends on how close to the core one's drilling site is. I assume the 1320 foot spacing would be in the core and wider spacing would be needed away from the core.
