Lime Rock Partners

Lime Rock Partners is a private equity firm focused exclusively on the upstream oil and gas sector, providing growth capital to exploration and production, mineral and royalty, and oilfield service companies. The firm targets businesses across North America, Europe, and the Middle East, committing $50 million to $150 million of equity per transaction in companies valued up to $500 million, and applies a highly selective approach, sometimes partnering with as few as one new company per year to concentrate resources and expertise on each opportunity. Transaction types include growth capital financings, joint ventures, equity commitments to non-operated asset acquisitions, and strategic partnerships with management teams, with the firm acting as a creative, flexible counterparty across deal structures. Lime Rock has built deep, recurring relationships with several portfolio teams over multiple cycles, including its long-running partnership with CrownQuest Operating on the CrownRock platform, one of the most active private drillers in the United States. Founded in 1998, the firm is headquartered in Westport, Connecticut, United States, with additional offices in Houston, Texas, and Aberdeen, Scotland.
