PERTH, Australia — Woodside Energy and Pemex are reassessing their contracting options for the deepwater Trion Field development offshore Mexico.
The goals are to improve predictability of the cost and schedule against the current backdrop of volatility in the supply chain, Woodside said in its latest results statement, ahead of a potential final investment decision next year.
Trion is thought to hold 2C contingent resources of 536 MMboe, 88% of which is oil. The partners plan a 24-subsea well development connected to a FPU producing and transferring 100,000 bbl/d of oil to a floating storage and offloading vessel.
Most of the produced gas will be injected into the reservoir to enhance oil recovery, with excess gas transported by a pipeline. Using new technologies and optimized operating practices, the project’s carbon emissions should be low for this type of deepwater development, Woodside said, at <15 kgCO
2e/boe compared to an industry average of 20 kgCO
2e/boe.
FEED studies for Trion finished in June.
In the US Gulf of Mexico (GoM), Woodside is participating in the currently drilling Starman-1 well, and it plans an operated well on the Hoodoo prospect in the western GoM later this year.
Co-owner Occidental recently took a 30% interest in the Hoodoo-1 well and 28 blocks around the prospect via a farm-down agreement.
Elsewhere in the region, Woodside gained a 44% interest in the Atlantis oil and gas development after acquiring BHP’s upstream petroleum business. Here an ocean-bottom node seismic acquisition was completed in June, designed to support future development opportunities
At Mad Dog (Woodside 23%), work is underway to drill an 11th producing well with three further wells or side tracks planned.
Drilling of the second Shenzi North subsea wells, both tiebacks to the Shenzi TLP, started in July, with first oil targeted for 2024.
