BHP Billiton said Jan. 22 the Trion-2DEL appraisal well, the first well drilled by an international operator in deep water offshore Mexico, struck oil.

The well, located in Block AE-0093 in the Gulf of Mexico (GoM), was spudded on Nov. 15 in a water depth of 2,379 m (7,805 ft). BHP said a downdip sidetrack is currently being drilled to further appraise the field.

The Trion Field is in the Perdido Fold Belt area in the deepwater GoM.

BHP is the operator and holds a 60% interest. Mexico’s state-owned Pemex holds the remaining interest.
