EnCap Investments is an American private equity firm specializing in the energy industry, particularly oil and gas.

Founded in 1988 and headquartered in Houston, Texas, EnCap Investments is a leading provider of venture capital to the independent sector of the U.S. oil and gas industry. The firm has a long history in the energy sector, having raised 18 private equity funds since its inception. While historically focused on upstream oil and gas, the firm has recently expanded its scope to include midstream assets and clean energy transitions.

In recent years, the firm has demonstrated a shift toward diversified energy holdings. In 2021, EnCap raised $1.2 billion for a fund dedicated to energy transition investments, specifically targeting wind and solar power projects. The firm also manages significant transactions in the fossil fuel space, such as the 2021 acquisition of Equinor's Bakken Formation assets for $900 million through its portfolio company, Grayson Mill Energy. Over its history, the firm has consistently ranked among the top global private equity firms by capital raised.
