BW Energy and its partners have made oil discovery in an exploration well in the Dussafu licence offshore Gabon.
The Hibiscus North exploration well (DHBNM-1) well is located about 6km north-northeast of the Hibiscus discovery well DHIBM-1, in a water depth of approximately 115m.
During drilling using the Borr Norve Jack-up rig, the DHBNM-1 well encountered Gamba structure at a depth of 2794m and identified around 13.5m of oil-bearing reservoir in the Higher Gamba sandstone.
BW Energy said the Upper Gamba sandstone is the primary target reservoir at the well.
The partners are continuing to drill the exploration well to intersect the secondary targets in the deeper Dentale Formation.
Once the well is drilled to a total depth of approximately 3,500m, the partners will undertake the oil discovery’s total depth, logging operations and evaluation.
Subsequently, drilling work of a side-track well will be carried out to delineate the field.
BW Energy expects the discovery to add to the Dussafu Block’s previous gross discovered recoverable resource estimate of approximately 105 million barrels gross.
The Dussafu licence is operated by BW Energy with a 73.5% stake. Other licence partners include Gabonese Oil Company (9%) and Panoro Energy (17.5%).
The Dussafu Marin Permit is a development and exploitation license comprising multiple discoveries. It includes six oil fields, namely Moubenga, Walt Whitman, Ruche, Ruche North East, Tortue and Hibiscus.
According to Panoro Energy, Dussafu’s exploration potential is significant with numerous Gamba and Dentale prospects.
Gabon is claimed to be the fourth-largest producer and exporter of crude oil in sub-Saharan Africa.
