The Mexican regulator, Comision Nacional de Hidrocarburos (CNH), has approved the Trion field development plan (FDP). Woodside (60%, operator), an Australian oil company, took final investment decision (FID) on the project in June 2023, with subsequent support from Pemex (40%), the Mexican state-owned petroleum company. The forecast total capital expenditure is US$7.2bn (including all 24 wells).
Trion is located in a water depth of 2,500 m, approximately 180 km off the Mexican coastline and 30 km south of the Mexico/US maritime border. The resources will be developed through a FPU with an oil production capacity of 100,000 bbl/d. The FPU will be connected to a FSO vessel with a capacity of 950,000 bbl of oil. First oil is targeted for 2028.
Crude is expected to be shipped to international markets and the development is expected to include 18 wells (nine producers, seven water injectors and two gas injectors) drilled in the initial phase, with a total of 24 wells drilled over the life of the Trion project. Gas that is not reinjected or used on the FPU will be delivered to the domestic natural gas pipeline network by a subsea gas pipeline.
