Walter Oil & Gas has made a commercial oil and gas discovery in the US Gulf of Mexico.
According to partner Talos Energy, the Ewing Bank 953 well (EW 953) encountered delivered around 127 ft of net pay in the targeted sand at a true vertical depth (TVD) of 19,000 ft. Talos interim president and CEO Joe Mills said the well logged better than anticipated rock properties.
Initial analysis suggests 15-25 MMboe could be recovered from a single subsea well, which the partners plan to tie back to the Timbalier 311 Megalodon platform. This could go onstream in mid-2026, at initial rates of 8-10,000 boe/d.
Talos is also participating in the Murphy-operated exploration well on the Sebastian prospect in Mississippi Canyon block 387. This began drilling in late August and is targeting the Upper Miocene K-1 reservoir at 12,000 ft TVD.
Sebastian is an amplitude-supported prospect that could hold 9 – 16 MMBoe, with a potential initial production rate of 6 – 10 MMboe/d. If successful, the accumulation would be tied back to the Delta House platform.
Talos has of late drilled a series of single-well prospects for potential subsea tiebacks to its offshore infrastructure in the GoM such as Venice and Lime Rock, Sunspear, and the Claiborne sidetrack.
“These drill-ready projects exemplify our focus on tactical, lower-risk opportunities that can be brought online relatively quickly and supplement our larger, longer lead drilling projects," said Mills.
