PetroCap Partners

What PetroCap Partners does

PetroCap Partners (legal entity PetroCap, LLC) is a Dallas-based private energy investment firm founded in 1992 that operates as a working interest partner in upstream oil and gas development projects across the United States. Unlike traditional private equity that acquires equity stakes in companies, PetroCap invests directly in projects, typically committing $25 million to $75 million of net capital per deal and taking a majority working interest. The firm shares project economics with operating partners through a back-in interest structure that activates after returns clear defined investment hurdles, aligning operator and investor incentives.

PetroCap's core offering is project-level capital combined with embedded technical, land, and finance expertise delivered through its in-house team, which works alongside operating partners throughout the project lifecycle. The firm maintains an active portfolio across five major US basins—Permian, Eagle Ford, Haynesville, Midcontinent, and San Juan—with operating partner relationships spanning Lakewood Energy, Catamount Energy Partners, Tascosa Energy Partners, Lynx, XDG Resources, Heritage Energy, and Ageron Energy. Beyond oil and gas, PetroCap extends its investment mandate into renewable energy through its affiliate Aplomado Partners.

The business model centers on principal investment returns rather than third-party fund management. The firm is founder/partnership-owned (Co-Founder Doug Evans) and led by a small Dallas-based team of 11–50 employees, with partners including Lane Britain and Brittany Glendenning (Partner, CFO & CCO). Deal sourcing is relationship-driven, relying on industry professional networks and existing operator referrals rather than traditional marketing channels, and investment terms are negotiated deal-by-deal rather than publicly disclosed.
