ABIDJAN -- The Lukoil/Vanco/Petroci partnership have completed drilling their first exploration well in Block CI-401 offshore Cote d’Ivoire.
Orca-1X-bis penetrated the targeted objectives and discovered thin sandstone reservoirs. The well was drilled by the drillship Deepwater Pathfinder to a total depth of 4,015 m (13,172 ft) below sea level in a water depth of 1,868 m (6,128 ft), at a location 55 km (34 mi) south of the port of Bassam.
Oil samples were recovered from Campanian and Turonian sandstones during the course of operations. The well has been plugged and temporarily abandoned.
Data obtained during drilling has opened up new information on the petroleum potential of the western part of the Tano-Ivoirian basin, and confirmed an active petroleum system, which could warrant future exploration in this area.
More than 3,000 sq km (1,158 sq mi) of 3D seismic data have been acquired in Block CI-401 and CI-101, where the same consortium holds a production-sharing contract. Currently, the partners are defining a location for the first exploration well in Block CI-101, due to be drilled in 2011.
