Talos Energy expects the Katmai West #2 appraisal well in the US Gulf of Mexico (GoM) to reach total depth in early 2025.
Seadrill’s West Vela drillship spud the well last month. Modifications have just finished at the host Tarantula platform in anticipation of a swift tie-in, with production capacity at the facility raised from 27,000 boe/d to 35,000 boe/d.
Talos expects first production from Katmai West #2, although rate-constrained under the upgraded capacity to allow for extended flat-to-low decline output from the platform.
The company will next use West Vela to drill the high-impact Daenerys subsalt well in the Walker Ridge area, targeting the regionally prolific Middle and Lower Miocene section, which could hold 100 MMboe to 300 MMboe.
Upon completion of operations at Daenerys, the drillship is due to spud the Helms Deep, near-infrastructure subsalt Pliocene well for Talos in third-quarter 2025. The planned depth is about 18,000 ft, with an estimated resource potential of 17 MMboe to 27 MMboe.
Last month, Talos (via its interest in Ridgewood Energy) contracted Transocean’s Deepwater Conqueror to complete its Sunspear discovery well from July 2023. This will be connected to the Prince platform and should go online in second-quarter 2025.
In September, the Ewing Bank 953 well encountered 127 ft of net pay in the target sand at 19,000 ft TVD. Early analysis suggests a recoverable resource range of 15 MMboe to 25 MMboe from a single subsea well.
Current plans call for the well to be tied back to the Walter Oil & Gas-operated South Timbalier 311 Megalodon platform (Talos 33.3%).
