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.

The development is subject to joint venture approval and regulatory approval of the field development plan (FDP), expected in the fourth quarter of 2023. Woodside is operator with a 60% participating interest and PEMEX Exploración y Producción (PEMEX) holds the remaining 40%.

The forecast total capital expenditure is US$7.2 billion (US$4.8 billion Woodside share including capital carry of PEMEX of approximately US$460 million) with the development expected to deliver strong returns to Woodside shareholders as well as economic and social benefits to Mexico.

The investment is expected to deliver an internal rate of return (IRR) greater than 16% with a payback period of less than four years. The forecast IRR excluding the capital carry is greater than 19%.

The project will target the development of an estimated 479 MMboe of Best Estimate (2C) Contingent Resource (100%) of oil and gas (287 MMboe 2C Contingent Resources, Woodside net economic interest). The subsurface has been extensively appraised, with six well penetrations undertaken across the field, informing Woodside’s understanding of this large, high-quality conventional resource.

The resource will be developed through a floating production unit (FPU) with an oil production capacity of 100,000 barrels per day. The FPU will be connected to a floating storage and offloading (FSO) vessel with a capacity of 950,000 barrels of oil.
