by Prathik Jayaprakash

Shell U.K. Limited, a subsidiary of Shell plc, and Equinor UK Limited, a subsidiary of Equinor ASA, have officially completed the merger of their UK offshore oil and gas operations to form a new company: Adura. Launched today, Adura becomes the largest independent producer in the UK North Sea.

Headquartered in Aberdeen, Adura is a 50/50 joint venture that combines decades of North Sea expertise. The new entity is strategically positioned to manage a high-performance, cost-competitive portfolio, maximizing the long-term value of vital UK energy assets.

"It is a rare privilege to lead a company in its first chapter," said Neil McCulloch, CEO of Adura, who brings over 30 years of energy sector experience to the role. "With a foundation built on safety, a deep belief in the North Sea’s future, and the combined expertise of Equinor and Shell, I am excited to begin working with this exceptional team."

Adura now manages Equinor and Shell’s interests in 12 major producing assets and active projects, including: Mariner, Rosebank, Buzzard, Shearwater, Penguins, Gannet, Nelson, Pierce, Jackdaw, Victory, Clair, and Schiehallion. The company also holds several exploration licenses. Approximately 1,200 staff members from both parent companies have transitioned to Adura, ensuring that industry-leading talent and technical knowledge are retained.

"Forming the UK's largest independent producer alongside Equinor is a historic moment for our business and the national energy industry," said Rich Howe, Shell’s Executive Vice President for Conventional Oil & Gas. "With its industry-leading expertise and asset base, Adura is perfectly positioned to lead in this mature basin."

Philippe Mathieu, Equinor’s Executive Vice President for Exploration and Production International, added: "Adura represents a new era for the North Sea. With the scale and operational flexibility required to succeed, the company is set for long-term impact, reinforcing the North Sea’s role in meeting the UK’s energy needs."

In 2026, Adura is projected to produce over 140,000 barrels of oil equivalent per day—more than any other producer in the UK North Sea, according to data from Wood Mackenzie.
