Hess has made an oil discovery with the Esox-1 exploration well drilled in the US Gulf of Mexico, with the find set to be fast-tracked as a subsea tie-back to the Tubular Bells platform.

The probe struck around 191 net feet of “high-quality oil-bearing Miocene reservoirs” after being drilled by Diamond Offshore Drilling-owned drillship Ocean BlackRhino in 4609 feet of water in Mississippi Canyon block 726 in the deep-water US Gulf, according to the US independent.
