US crude production has already peaked, according to one of the country’s leading shale executives, as producers battered by the price crash shun new output growth and start trying to become profitable. Matt Gallagher, chief executive of Parsley Energy, one of Texas’s biggest independent oil producers, said the record output level struck earlier this year would be the high-water mark.

“I don’t think I’ll see 13m [barrels a day] again in my lifetime,” the 37-year-old Mr Gallagher told the Financial Times. “It is really dejecting, because drilling our first well in 2009 we saw the wave of energy independence at our fingertips for the US, and it was very rewarding …  to be a part of it.”

American oil output plunged by as much as a quarter this spring, as crude prices crashed in the wake of a Saudi-Russia price war and the coronavirus outbreak, prompting several operators, including Parsley, to shut wells and slash planned spending. Soaring shale production helped the US become a net exporter of petroleum in November last year – a stunning reversal for a country that imported more than 10m b/d a decade earlier. Since May, however, that has reversed and net imports have trended upwards.

US oil briefly traded below zero in April, but a recovery to around $40 a barrel since then still leaves it beneath the break-even price for many shale producers. It was “hands down” the worst oil- price crash in recent history, Mr Gallagher said, and would have a lasting impact on the sector. “Our industry is the industry of mobility and comfort,” he said – referring to fuel for car and air travel and for heating and air conditioning –  “and mobility is being drastically rethought and there will be new innovations on comfort.”

The Parsley chief has earned a reputation as a progressive voice within Texas’s oil industry. He took to Linkedin with his thoughts on George Floyd’s killing, and recently bought a Ford electric car.
