LONDON–(BUSINESS WIRE)–Warwick Capital Partners (“Warwick”), a global specialist strategies investment manager, is pleased to announce the successful acquisition of $670 million in assets to affiliates of Warwick and GRP Energy Capital (“GRP”), acquired from Viper Energy (“NASDAQ: VNOM” or ”Viper”), a subsidiary of Diamondback Energy (“NASDAQ: FANG” or “Diamondback”). The transaction, with an effective date of September 1, 2025, represents one of the largest recent deals in the U.S. oil and gas royalties sector.

The portfolio of 73,500 net royalty acres spans the DJ, Eagle Ford and Williston basins. The full year 2026 average daily production from the assets is estimated at approximately 4,500 to 5,000 barrels of oil per day, with a total of 9,000 to 10,000 barrels of oil equivalent per day.

This latest acquisition follows the 2023 sale of certain mineral and royalty interests from affiliates of Warwick and GRP to Viper in exchange for approximately 9.02 million Viper common units and $750 million of cash.

The deal marks another milestone in Warwick and GRP’s decade-long partnership in managing US oil and gas mineral interests, with total acquisitions of over $1.5 billion across more than 325 individual transactions.
