Post Oak Energy Capital closed its second fund, Post Oak Energy Partners II, with $600 million in commitments, the company said Feb. 4.

The fund was closed at a hard cap of $500 million in a single closing, and Post Oak Energy Capital’s existing funds were increased by $100 million, the company said, adding that they will co-invest alongside Post Oak Energy Partners II.

"We are pleased that our strategy and team have the support of some of the most experienced private energy investors in the world," said Frost Cochran, managing director of Post Oak Energy Capital.

He added, "our management team's industry backgrounds and investment experience will continue to create unique opportunities for our funds."

The Post Oak Energy Partners II fund will be used for corporate growth capital, development, acquisitions and recapitalizations, the company said.

Like the first fund, Post Oak Energy Partners LP, this most recent fund will invest in North American oil and gas companies, oilfield services and infrastructure, the company said.

Post Oak Energy Capital, established in 2006, is an energy-focused private equity firm based in Houston.
