Chevron announced Monday that it has agreed to buy rival Hess in yet another oil industry consolidation deal.

Cash-rich oil giants are taking advantage of high prices and surging profits to snap up assets and boost returns for shareholders even as pressure builds for them to invest more in renewable energy.

The deal, worth $53 billion plus debt, would give Chevron even greater access to US shale production in Texas’ Permian Basin, a part of the industry where Chevron (CVX) has been a leader for years. Hess (HES) also has large oil assets in Guyana, which Chevron said would help grow its production over the next decade.

“This combination positions Chevron to strengthen our long-term performance and further enhance our advantaged portfolio by adding world-class assets,” said Chevron Chairman and CEO Mike Wirth.

Wirth said Chevron and Hess will be able to merge seamlessly, sharing “similar values and cultures,” including a commitment to “lowering carbon,” although environmental advocates have been very critical of oil companies’ slow acceptance of renewable energy alternatives.

Chevron said buying Hess would increase the company’s free cash flow, giving the company more cash on hand in the long term to do more share repurchases. Chevron said that it would increase buybacks of its stock by $2.5 billion to $20 billion a year.

Critics have slammed oil companies for spending tens of billions of dollars on stock buybacks rather than easing the pain for consumers at the pump or investing more heavily in the energy transition. Already cash rich, oil companies have scored record profits after Russia’s invasion of Ukraine pinched oil supplies and sent prices higher.

ExxonMobil (XOM) last year made a record $1,874 of profit for every second during the course of 2022.

Those profits have made oil companies deal-happy. Two weeks ago, Exxon announced it would buy shale company Pioneer for $60 billion, more than doubling Exxon’s Permian Basin operations.

Chevron is no stranger to big deals. In 2019, it bought Anadarko Petroleum to add to its shale business.

Hess CEO John Hess said the combined company would be “stronger in every respect” and would deliver shareholder value. The companies said the deal would save about $1 billion in cost synergies.

Hess in 2014 sold off its retail gas station business to Marathon for $2.6 billion. But the company’s famous Hess truck toys survived. The company did not announce whether the Hess brand would live on post-merger.
