MEXICO CITY, Dec 5 (Reuters) - Australia's BHP Billiton (LON:BLT) on Monday won the contest to partner with Mexican state oil company Pemex in a joint venture to develop a deep water field in the country's untapped Gulf waters.
A local unit of BHP Billiton BHP.AX won the rights to tie-up with Pemex on its light oil Trion field, less than 50 miles (80 km) from the U.S.-Mexico maritime border.
BHP outbid Britain's BP BP.L , the only other company that participated, with a $624 million offer to complement its royalty bid, the country's oil regulator said.
