Kosmos Sets Sights on Offshore LNG

Kosmos Energy announced that it increased its working interest to 90%, after BP’s exit, and assumed operatorship of the Yakaar-Teranga gas discoveries offshore Senegal. Yakaar-Teranga is one of the world’s largest gas discoveries in recent years and holds around 25 Tcf of advantaged gas in place, according to the company.

Kosmos has partnered with Petrosen and the Government of Senegal on the development of a concept that prioritizes cost-competitive gas to the domestic market, as well as the development of an offshore LNG facility targeting exports into international markets. The planned LNG facility would allow approximately 550 MMcf/D of domestic natural gas transported via pipeline to shore and export volumes liquified on a floating LNG vessel.

Discoverer Makes Discovery in Guyana

Offshore Guyana is home to one of the latest oil discoveries of 35 m of net pay at the Wei-1 well on the Corentyne block. The discovery is thanks to the partnership of CGX Energy Inc. and Frontera Energy Corp., with the joint venture believing that the rock quality discovered in the Maastrichtian horizon in the Wei-1 well is similar to that reported in the Liza Discovery on Stabroek Block. Results further demonstrate the potential for a standalone shallow-oil resource development across the Corentyne block, according to the companies.

The Wei-1 well was safely drilled by the Noble Corp.’s Discoverer semisubmersible mobile drilling unit in water depth of approximately 583 m to a total depth of 6233 m, according to the companies. A total net pay of 104 m has been discovered on the Corentyne block to date.

Confirmed Spud in Namibia

Sintana Energy Inc.’s PEL 83 license in Namibia’s Orange Basin has been spud. The Mopane X1 exploration well is the first of two wells which are scheduled to be drilled by the semisubmersible rig Hercules under a contract that provides for the two wells and optional testing, according to the company. PEL 83 is located north of PEL 39, home to Shell’s basin opening, Upper Cretaceous discoveries at Graff-1, La Rona-1, and Jonker-1.

Sinata also confirmed public filing of an application by an affiliate of Chevron Corp. with the Ministry of Environment, Forestry, and Tourism for the Republic of Namibia for an environmental clearance certificate which would provide for the drilling of up to five exploration and five appraisal wells beginning in Q4 2024 on block 2813B which is governed by PEL 90.
