What specific exploration and production opportunities will INEOS and Shell jointly pursue in the Gulf of Mexico?

The partnership will initially focus on three exploration and production opportunities: Shell's Fort Sumter discovery, the drilling of the Sisco exploration well, and a further exploration well targeted by the end of 2030.

What is INEOS's working interest in the jointly explored assets, and how does it align with its existing ownership stakes?

INEOS is acquiring a 21% working interest in these assets for an undisclosed amount, consistent with its ownership in Appomattox, Rydberg, the recent Nashville discovery, and the Mattox pipeline.
