OSLO, Norway Exploration drilling has finished on the Hibiscus Updip prospect in the Dussafu license offshore Gabon.

According to operator BW Offshore, results exceeded expectations, with early analysis indicating 40-50 MMbbl of oil recoverable.

Initially the jackup Borr Norve drilled the DHIBM-1 exploration well to a TD of 3,538 m (11,607 ft), in a water depth of 116 m (380 ft). Logging and sampling data confirmed that the well delivered around 21 m (69 ft) of pay from a 33-m (108-ft) hydrocarbon column in the Gamba formation.

Subsequent appraisal side track (DHIBM-1 ST1), 1,100 m (3,609 ft) to the northwest, encountered 26 m (85 ft) of pay in the Gamba. The oil-water contact was at the same level in both wells, proving continuity of the hydrocarbon accumulation.

This was the BW-led partnerships fourth consecutive oil discovery on the license, said CEO Carl K. Arnet. The Hibiscus discovery and its surrounding prospects represent another area of significant potential in the Dussafu block and we are looking forward to the next phase of the program as we continue to unlock the potential of the Dussafu field.

DHIBM-1 was designed to appraise one of various prospects in the greater Ruche area. BW will next turn its attention to optimizing a planned future development.

The Borr Norve, meanwhile, will drill four subsea production wells on the Tortue field all tied back to the FPSO BW Adolo followed by another exploration well.
