The Trion field is located in the Perdido Foldbest, Gulf of Mexico, at a water depth of 2,500m approximately 180km off the Mexican coastline and 30km south of the US/Mexico maritime border. 

Trion is a greenfield development that would represent the first oil production from Mexico’s deepwater, with potential for future discoveries to be tied back to Trion facilities.

The Trion project was discovered by PEMEX (Mexico’s state-owned petroleum company) in 2012. In 2017, BHP Petroleum and PEMEX signed an agreement for the development of the Trion discovery. Following the merger with BHP Petroleum, Woodside will continue the agreement with PEMEX for field development. 

Woodside is targeting a potential final investment decision (FID) in 2023.
