Kombe-N’sepe Block
Location: Coastal strip of Douala Basin bordering Gulf of Guinea south of the city of Douala (predominantly onshore); block extends more than 100 kilometers (60 miles) south of the city of Douala
Size: 3,026 km2 (748,000 acres)
Contract: association
Working interest: 35%
Operator: Perenco
Partners: Perenco, 40% working interest; Société Nationale des Hydrocarbures (SNH), 25% working interest
The Kombe-N’sepe Block is located at the northern end of the late Cretaceous turbidite play fairway that extends from northern Gabon through Equatorial Guinea into southern Cameroon. More than two billion barrels of oil have been discovered in the region. Operators have made several small oil and gas discoveries in and around the Kombe-N’sepe Block. Generally, explorers have not focused on this late Cretaceous play where Kosmos recognizes several promising leads in stratigraphic pinch-out and combination structural traps located in well-developed channel systems. Kosmos and its partners have prioritized prospects identified by reprocessed seismic data and are integrating recent well results into the exploration program.
Ndian River Block
Location: Coastal strip of Rio del Rey Basin bordering Gulf of Guinea and abutting Cameroon/Nigeria border (predominantly onshore)
Size: 2,510 km2 (620,000 acres)
Contract: production sharing
Working interest: 100%
Operator: Kosmos Energy
Partner: Société Nationale des Hydrocarbures will be carried through exploration and appraisal phases and has an option to back in to the project with an interest of up to 15% upon approval of a development plan
Previous oil and gas drilling offshore in the vicinity of the Ndian River Block has confirmed the presence of a working petroleum system, particularly in bordering portions of the Rio del Rey Basin, which has long-established production. Kosmos initially is focusing on the Ndian River Block’s underexplored northern extension of the late Cretaceous/lower Tertiary turbidite play, which has been successful in adjacent regions. Since 2007 exploration activities have included a gravimetric and magnetic survey of the block, field studies, reprocessing of existing data and a 2D survey over an area with the highest potential. The company anticipates its first well on the block will target the Liwenyi prospect in 2012.
