墨西哥石油和天然气：墨西哥国家石油公司宣布为特来恩区块招标过程（

During Mexico's "Round 0" selection process, state-owned Pemex enjoyed the preferential right to designate those onshore and offshore oil fields that Pemex wished to develop. Among the blocks selected by Pemex is the ultra-deepwater Trion block, located 30 kilometers south of the maritime border between Mexico and the United States in the Gulf of Mexico and 200 kilometers east of Matamoros. Having a total area of 1,250 square kilometers and with a water depth of approximately 2,500 meters, the Trion block borders several of the deepwater blocks that will be auctioned in December 2016 as part of Mexico's Round 1 sale process.

Pemex estimates that the Trion has probable reserves of approximately 485 million barrels of oil equivalent, which is roughly equal to the total probable reserves of all other Round 1 blocks combined, and it will require upward of US$11 billion to develop.
