(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 companies said the collaboration supports disciplined growth while expanding INEOS Energy’s upstream portfolio and reinforcing long-term supply.
The Appomattox hub, a key deepwater production center, is expected to serve as the anchor for future tieback developments in the region.
