Private-equity firm EnCap Investments LP closed EnCap Energy Capital Fund X LP, the company said April 8.

The fund closed with $6.5 billion of limited partner capital commitments, reaching its hard cap oversubscribed.

Fund X supports North American upstream management teams.

EnCap Investments is led by its founders, managing partners David B. Miller, Gary R. Petersen, D. Martin Phillips and Robert L. Zorich.

Jason M. DeLorenzo, E. Murphy Markham IV and Douglas E. Swanson Jr. are the three additional managing partners, the company added.

“We are very fortunate to have received such strong support from our existing investor base, especially during a period of significant volatility in our industry. Our long-term partnership with many high-quality institutions and our extensive track record in the business allowed for a quick and efficient fundraise, which positions us well to respond to the market opportunities that are likely to arise in this cycle,” said Swanson.

Houston-based EnCap Investments has managed more than $27 billion in capital commitments from about 300 institutional investors.
