Shale Efficiency May Have Hit Its Peak For Now

From Oilprice.com:
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).

Fracktivist in Dimock Releases Carefully Edited Video, Refuses to Release the Rest

From Energy in Depth: There is something very strange going on along Carter Road, in Dimock, Pennsylvania, and I’m not speaking of natural gas, methane migration, contamination, litigation or even the extensive water testing there by the EPA and others.  No, I’m talking about a new “Watergate” conspiracy, complete with 18 minutes of missing tape (well, video, actually). It seems the ever-present Green Party member and  naturist   Vera Scroggins  (a/k/a  Vera Duerga ) has posted a video of Craig Sautner meeting with the EPA.  Mysteriously, the video is but 14 seconds in length, cutting off conversation in what is obviously mid-stream.  It raises a question Craig Sautner, like  Ronald Reagan in Kings Row , might have asked, “Where’s the rest of me?’  Carter Road, isn’t Kings Row, of course, (at least not until you arrive at  the mansion Scott Ely, one of the Dimock litigants, is building with his royalty money ), but there appears to be...

The Second Largest Oil and Gas Merger - Cabot and Cimarex

By -

       Due to investor pressure, the U.S shale drillers are being pushed to improve financial and operational performance after a few years of poor returns. Even though the industry has improved its numbers, when compared to last year, investors still want more to be done for them to earn more money.      That's why two mid-tier shale drillers, Cabot and Climarex, have decided to merge in order to eliminate $100 million in annual costs, which means more money for the investors. This all-stock transaction is valued at about $7.4 billion, which is relatively high for the oil and gas sector.      The new entity will be renamed and the headquarters located in Houston, Texas. Cabot shareholders will own 49.5 percent of the new entity, and Climarex the rest.       The Cimarex-Cabot merger will address the investor's demand for a higher amount of returning cash. The initial plan is to pay a 50-cent-per-share special dividen...

Do You Know The History of Fracking?

By -

  In 2018, 59% of total oil production in the U.S came from hydraulic fracking, which means it accounted for more than two-thirds of domestically manufactured gas. By 2024, fracking will reach an astounding $68 billion market value! Of course, fracking is not a new drilling method as you can trace it back hundreds of years. That's why we want to consider the history of hydraulic fracturing (fracking). We will be stating historical facts about it and focusing on the major historical occurrences that have influenced modern-day fracking. Pre-Fracking Days The idea of fracking started back in 1862 when Edward A.L. Roberts (Civil War veteran) witnessed Confederate soldiers exploding artillery rounds into a canal that obstructed a battlefield. At the time, Edward A.L. Roberts called it superincumbent fluid tamping. On April 26th, 1865, Edward A.L. Roberts began experimenting with exploding torpedoes, which consisted of lowering a torpedo containing an amount of powder from fifteen to tw...
