The Shell operated well, Nashville, marks INEOS’ first successful exploration well in the region.

The Nashville exploration well was drilled more than five miles beneath the seabed and confirmed high-quality oil in one of the Gulf’s most promising deepwater formations.

The discovery could be linked to the nearby Appomattox production platform, which is operated by Shell and jointly owned by INEOS.

David Bucknall, CEO of INEOS Energy, said: “This is a good result for INEOS Energy and an important step in building our presence in the Gulf where world-class resources are to be found and developed responsibly. We believe Nashville will help strengthen energy security and provide reliable supplies for many years to come.“

The company said the discovery was drilled using the Deepwater Proteus, one of the world’s most advanced offshore rigs. Further technical work is now underway to determine the size of the find.
