Bryan Sheffield made his fortune drilling wells in America’s largest oilfield, much like his father and grandfather before him. But as the shale boom slows in the Permian basin, the oil executive is leading efforts to export the US fracking revolution overseas.
Sheffield is the biggest shareholder in Tamboran Resources, which holds drilling rights over almost 2mn acres of land in northern Australia’s Beetaloo basin. Tamboran expects to start selling gas from a pilot shale project in the area later next year.
Formentera Partners, the private equity group he co-founded, is also exploring opportunities in shale fields in Venezuela following Donald Trump’s removal of strongman leader Nicolás Maduro.
The Permian has been a massive wealth creator for America, but we’ve drilled the best prospects and are running out of inventory,” said Sheffield, who founded Parsley Energy before selling it for $7.5bn including debt in 2021.
“Americans will need to explore outside of America in the next three to five years and use their expertise to develop new shale basins,” he added.
The shale boom began in the mid-2000s when hydraulic fracturing and horizontal drilling unlocked vast reserves in sedimentary rock, enabling the US to leapfrog Saudi Arabia and Russia and become the world’s largest producer of oil and gas. It created tens of thousands of jobs and bolstered US energy security by breaking its dependence on the Opec oil cartel.
But the expansion phase appears to have peaked, with the US Energy Information Administration forecasting a year-on-year flattening of production at 13.6mn barrels a day in 2026 and a fall to 13.2mn barrels in 2027, as US drillers cut costs and slow output amid weak crude prices.
There’s no expectation of material growth [in US shale], and some foresee gradual decline starting in the near term,” said Ruaraidh Montgomery, analyst at market intelligence firm Welligence.
To counter this, he continued, “some American shale companies are now looking to diversify abroad and partner with local companies, which gives them first-mover advantage over other US rivals”. Experts say some of the best opportunities are in the Middle East, where EOG Resources, a Houston-headquartered company with assets in the Permian, has signed deals with the national oil companies of the United Arab Emirates and Bahrain.
Harold Hamm, the shale pioneer behind Continental Resources, has struck a partnership with Turkey’s national oil company and snapped up acreage in Vaca Muerta, the Argentine formation where Chevron is also invested.
Continental plans to invest $200mn a year drilling in Argentina.
“We do know there is a real and recognised degradation in the inventory quality of the US unconventional resources,” said Doug Lawler, chief executive of Continental Resources, adding that US oil production is set to plateau, prompting operators to look abroad.
