The Trion project, Woodside's first oil production in Mexico's Gulf, is set to deliver shareholder value with first oil targeted for 2028.

The Trion field is located in the Perdido Fold Belt, 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 has made a final investment decision to develop the large, high-quality Trion resource in Mexico. The expected returns from the development exceed Woodside’s capital allocation framework targets and deliver enduring shareholder value. First oil is targeted for 2028.
