Drilling operations in Gabon

Dussafu Drilling Update

GABON: The DHIBM-3H production well has been successfully drilled, completed and handed over to production operations without incident. The well encountered good quality oil saturated reservoir sands in the regionally prolific Gamba formation.

First oil from the well is expected in early April. Commissioning and start-up of the new gas lift compressor will follow the first oil activities on the FPSO. 

The DHIBM-3H well was drilled from the BW MaBoMo production facility to a depth of 3,883 metres into Gamba sandstone reservoir in the Hibiscus field. Drilling operations began at the start of the year with batch setting of conductors and surface casing on three Hibiscus wells.

The drilling campaign followed the successful installation of the production facility, risers, and pipeline. DHIBM-3H drilling results (drain length and reservoir properties) are in line with expectations. The oil produced at Hibiscus / Ruche will be processed on the BW Adolo FPSO together with the established Tortue production before offloading to oil tankers. 

The 20-kilometre pipeline connection between the BW MaBoMo production facility installed at the Hibiscus field and the FPSO BW Adolo moored at the producing Tortue field has been commissioned and all facilities and infrastructure are ready to receive oil from the new Hibiscus Ruche wells as they are drilled and completed. Commissioning and start-up of the new gas lift compressor to support production from all six existing wells at the producing Tortue field will follow first oil activities on the FPSO BW Adolo.
