BW Energy has spudded an exploration well on the Hibiscus Updip prospect on the Dussafu Marin permit. Partner Panoro Energy said the well, being drilled with the Borr Norve jackup rig, was the first well in a six-well campaign planned on Dussafu in 2019-20. The Hibiscus Updip well (DHIBM-1) is planned as a vertical well to test the Gamba and Dentale reservoirs at a site about 56km offshore Gabon in a water depth of 116 metres.
