What Westlawn does
Westlawn Group LLC is a privately held, Houston-based investment firm founded in 2021 that deploys long-term capital into the global oil and gas industry. The firm acquires both operated and non-operated interests across producing properties, development assets, and exploration opportunities, with a stated focus on production-enhancing technologies. Its investment mandate spans the United States (Lower 48, Gulf of Mexico, Alaska), Canada, Latin America, the Caribbean, and the Middle East.
Westlawn operates as a holding platform with multiple wholly-owned portfolio companies, each focused on a distinct asset class or geography. Westlawn Americas Offshore (WAO), formed in December 2023, acquires and develops high-quality deepwater oil and gas assets in the Americas, with current net production of nearly 20,000 boe/d across Gulf of Mexico, Brazil (20% working interest in BS-4 concession), Peru (30% working interest in Z-61/Z-62/Z-63 blocks), and other regional assets. Ellipsis U.S. Onshore Holdings, formed in 2023 and based in Dallas, targets large-scale, non-operated working interests in U.S. onshore basins including the Permian and Delaware, with pro forma production of approximately 20,000 boe/d. Westlawn Middle East LLC was established in 2024 and has signed a Feasibility Study Agreement for Block 71 in Oman using Salamander Solutions' proprietary electric heating technology for heavy crude extraction.
The firm's business model is centered on long-term partnership with best-in-class management teams, flexible deal structures (working interest acquisitions, farmouts, joint ventures), and co-investment with institutional capital partners including EnCap Investments and Rice Investment Group. Revenue derives from oil and gas production across consolidated subsidiaries, asset value creation, and strategic divestitures. The firm maintains a small core team (11-50 employees) augmented by subsidiary-level operating leadership, and its limited public footprint suggests a relationship-driven, deal-by-deal capital deployment model rather than a high-velocity transaction approach.
