What Formentera Partners does

Formentera Partners is a private investment firm based in Austin, Texas that acquires, operates, and improves unconventional oil and natural gas assets in mature US shale basins (Anadarko, Bakken, Barnett, Eagle Ford, Gulf Coast, Permian, Appalachia) and, more recently, Australia's Beetaloo Basin. The firm invests primarily through closed-end private equity funds, with Fund II closed at $828.5 million in 2023 and Fund III closed oversubscribed at $1.31 billion in October 2025, bringing total investor commitments to $2.8 billion. Capital is sourced from institutional investors, family offices, and individual investors, with Eaton Partners serving as exclusive placement agent.

The firm's investment strategy targets mature, low-decline producing assets with predictable production profiles, a basin-agnostic and balanced commodity mix, systematic hedging to establish a commodity-price floor, and conservative leverage to maximize free cash flow and reliable investor distributions. Operations are executed through a wholly-owned operating platform (referenced as formenteraops.com), with the firm directly employing more than 300 field and asset staff supporting approximately 3,900 wells producing nearly 70,000 barrels of oil equivalent per day across six US states (Texas, Oklahoma, North Dakota, Louisiana, Mississippi, Pennsylvania). Internationally, the firm has established Daly Waters Energy as a wholly-owned subsidiary to operate Australian Beetaloo Basin acreage and has partnered with INPEX Corporation (Japan's largest E&P) on a joint venture valued at up to $208 million in phased earn-in (plus a $266-411M option) and with Tamboran Resources via a $28.5 million farm-in agreement.

Underlying technology consists of modern shale-gas extraction techniques combined with proprietary data analysis for asset evaluation, capital allocation, and inventory characterization. Two oil and gas patents are held by Senior Reservoir Engineer Ruslan Filyukov. The firm monetizes assets through two distinct revenue streams: oil and gas production revenue from operated wells (the dominant contribution at consolidated level, given ~70K BOE/day output) and management fees plus potential carried interest at the fund manager level. Distribution is private placement only, with no public marketplace listing, and the firm is led by Managing Partners Bryan Sheffield (former Parsley Energy founder/CEO) and Blake London (former Credit Suisse Head of Energy Equity Capital Markets).
