US shale oil collapsing: Permian Basin as the last bastion

Crude oil production in the United States has decreased by more than 10% since the record high of 2015, from 9.6 million barrels per day (mmbpd) to less than 8.6 mmbpd. However, the drop in shale oil production has reached almost 20%. Moreover, if the increasing Permian Basin production were put out of the equation, the decrease in US shale oil output would be about 33%! And this fall will deepen as the number of new wells is still not sufficient. The collapse of the shale oil production is related to the decline curve of tight oil, but shale oil well production starts to decline much faster than that from regular wells. Continue reading
