DALLAS, Texas – Kosmos Energy has issued updates on its field developments in the Gulf of Mexico and West Africa in a results statement.

In the US GoM, the first two wells have been completed at the Beacon Energy-operated Winterfell project, with start-up anticipated during 2Q 2024. The third well will follow later in the year.

Kosmos and its partners are assessing subsea tieback options for last October’s Tiberius discovery in Keathley Canyon block 964, which encountered around 250 ft (~75 m) of net oil pay in the primary Wilcox target.

Tiberius is in 7,500 ft (2,300 m) of water. Initial fluid and core analysis suggests characteristics analogous with similar nearby discoveries in the Wilcox trend.

A decision on a phased development could take place later this year. The discovery is six miles southeast of the Occidental-operated Lucius production facility. In the Gulf of Mexico Lease Sale 261, Kosmos and Occidental were also awarded three blocks close to Tiberius, which include the Logan oil discovery.

At Odd Job, a subsea pump project to sustain long-term production from the field is nearing completion and the facilities should be in service by mid-2024. A workover on the Kodiak 3 well should get under way around the same time.

Offshore Mauritania and Senegal, all four wells for the bp-operated Greater Tortue Ahmeyim development have been drilled and completed, with production capacity set to be significantly higher than what is needed for first gas. Installation of the infield flowlines and subsea structures should finish by mid-year.

Hookup is under way offshore of the FLNG Gimi, which recently arrived from the yard in Singapore. The FPSO remains in a shipyard in Tenerife for inspection and repair of the fairleads, but the vessel should be ready to depart for the project site in April, ahead of final hookup and commissioning, allowing for first gas to flow during 3Q 2024.

At the Tullow Oil-operated Jubilee field offshore Ghana, one new producer well and one injector have come online this year with three additional wells expected to start up in the coming months.
