Frequently asked questions

Who runs investment decisions at EnCap Investments?

Day-to-day investment leadership sits with Managing Partners Jason M. DeLorenzo and Douglas E. Swanson, Jr., who have been with the firm since 1999. Each of EnCap's three verticals — upstream, midstream (EnCap Flatrock Midstream), and energy transition — operates under its own senior team with dedicated deal-level authority. The midstream platform, for example, is led by Managing Partners Gregory C. King and Samuel G. Pitts.

How is EnCap structured across its different energy verticals?

EnCap runs three distinct investment platforms. The upstream group backs oil and gas exploration and production companies. EnCap Flatrock Midstream, formed in 2008, provides growth capital to North American midstream infrastructure businesses. The energy transition team invests in opportunities tied to lower-carbon energy systems. Each vertical maintains its own investment professionals and sourcing networks while sharing EnCap's centralized investor relations and fundraising apparatus.

What is EnCap Flatrock Midstream and how does it relate to the broader firm?

EnCap Flatrock Midstream is a dedicated midstream investment platform formed in 2008 by William D. Waldrip, William R. Lemmons Jr., and Dennis F. Jaggi under the EnCap umbrella. It focuses on identifying, investing in, and building value in midstream infrastructure companies and assets across North America. The platform operates with its own management team and offices in San Antonio, Houston, and Oklahoma City.

Does EnCap invest through fund commitments or only direct deals?

EnCap invests through a series of institutional limited-partnership funds, having raised 25 funds totaling over $47B. The capital is deployed directly into portfolio companies — the firm does not operate as a fund-of-funds. It provides equity capital to management teams pursuing early-stage and growth strategies within the upstream, midstream, and energy transition sectors.

Where do EnCap's portfolio companies typically operate geographically?

EnCap's investment focus is overwhelmingly North American, centered on U.S. unconventional basins for upstream, major pipeline and gathering corridors for midstream, and domestic energy transition projects. The firm also has exposure to Canada through investments such as Rangeland Midstream Canada, a portfolio company of EnCap Flatrock Midstream.

What is EnCap's known posture on co-investments alongside external general partners?

EnCap historically operates as the lead or sole institutional equity provider to its portfolio companies rather than as a minority co-investor in deals led by other sponsors. Its model is to identify seasoned management teams, fund their business plans directly, and provide strategic and technical support. The firm's website emphasizes creating partnerships with management, not club-deal arrangements with competing GPs.

How has EnCap's strategy evolved to address the energy transition?

EnCap has added a dedicated energy transition vertical targeting investments created by the global shift to a lower-carbon energy system. This team operates alongside the long-standing upstream and midstream platforms. The firm publicly committed to incorporating ESG factors into its investment process, stating this aligns with its fiduciary duty, and has backed transition-focused companies such as Broad Reach Power.
