The shallow water block was awarded to ChevronTexaco and PTTEP International Ltd in July 2003 with the Mitsui stake to come from Chevron Offshore’s 85% holding.

ChevronTexaco recently made two discoveries within the G4/43 block. In a statement the company said, “During the period the sale to Mitsui was being formalised, two exploration wells in the block found oil and gas, although in quantities not yet provably commercial.”
