Woodside Energy made a final investment decision to develop the Trion resource in Mexico, 19 miles south of the US-Mexico border and 112 miles from the Mexican coastline in 8,200 ft of water. First oil is targeted for 2028.
The project will target an estimated 479 MMboe of best estimate (2C) contingent resource of oil and gas. The subsurface has been extensively appraised with six well penetrations across the field.
Trion will be developed with 18 wells (nine producers, seven water injectors, and two gas injectors) drilled in the initial phase and a total of 24 wells drilled over the life of the project. A 100,000 b/d capacity floating production unit (FPU) will connect to a floating storage and offloading (FSO) vessel with a capacity of 950,000 bbl of oil (OGJ Online, Dec. 10, 2020).
The development is subject to joint venture approval and regulatory approval of the field development plan, expected in fourth-quarter 2023. Forecasted total capital expenditure is $7.2 billion.
Woodside is operator at Trion (60%) with partner PEMEX Exploración y Producción (40%).
