Shell, INEOS advance tieback opportunities near Appomattox hub

May 05, 2026

(WO) - INEOS Energy and Shell Offshore Inc. have agreed to pursue new exploration and development opportunities tied to the Appomattox platform in the Gulf of America, targeting near-field resources that can be developed via subsea tiebacks.

The agreement focuses on prospects within tieback distance of existing infrastructure, including Shell’s pre-FID Fort Sumter discovery, the planned Sisco exploration well and an additional exploration target expected by the end of the decade.

INEOS will acquire a 21% working interest, aligning with its existing position across Appomattox and nearby assets, including Rydberg and the Mattox pipeline system. The strategy centers on leveraging established infrastructure to accelerate development timelines, control costs and deliver higher-margin production.

“Partnering with Shell on these opportunities is a natural step,” said INEOS Energy CEO David Bucknall. “We are focusing on areas close to existing infrastructure where we can move quickly, control costs and unlock new production.”

The agreement also comes as INEOS leadership continues to voice concerns about upstream policy in Europe. Chairman Brian Gilvary criticized the current UK energy approach, calling it “almost ideological political vandalism of a natural resource,” and argued that limiting domestic development is unlikely to persist given the importance of national energy supply.

“We’ll continue to look for bolt-ons… around the existing infrastructure we’ve got,” Gilvary added, pointing to further potential in the Gulf.

The Appomattox hub is expected to serve as a key anchor for future tieback developments in the region.
