BW Energy has decided to proceed with a sidetrack of the DH1BM-1 well on the Dussafu Marin Permit, located offshore Gabon, as the discovery may be bigger than expected.
BW Energy, a subsidiary of FPSO operator BW Offshore, is the operator of the Dussafu permit.
BW started drilling the Hibiscus Updip well (DHIBM-1) in mid-August, using the Borr Norve jack-up drilling rig. The well is located about 56 km offshore Gabon in 116 m water depth.
At the end of August, BW encountered hydrocarbons at the Hibiscus Updip Prospect.
Panoro Energy, BW’s partner, said in an update on Wednesday that the DHIBM-1 well was drilled on the Hibiscus Updip prospect and reached a Total Depth of 3,538 meters.
An oil discovery was made in the Gamba formation with an overall hydrocarbon column of 33 meters and average porosities ranging between 21% and 23%. The initial results of logging the Gamba formation at Hibiscus Updip are highly encouraging, Panoro noted.
BW’s preliminary assessment indicates that the discovery may be larger than the gross pre-drill estimate of 12 million barrels of prospective resources. Therefore, the Joint Venture partners have decided to proceed with a sidetrack of the DH1BM-1 well.
BW said that Hibiscus will be a separate development to the Ruche complex.
