Tortue partners add exploration well to Phase 2 drilling campaign
According to Panoro Energy, a rig should mobilize to the well site in July, followed by drilling of four wells for Phase 2 of the Tortue field development.
All will be subsea horizontal oil development wells – three through the Gamba reservoir and one in the Dentale D6 reservoir. The campaign should conclude in early 2020. Production from the new wells should start flowing later that year, lifting total output from Tortue to potentially 25,000 b/d.
Hibiscus Updip is mapped as a four-way closure at the Gamba level. BW believes it could contain recoverable volumes similar in magnitude to the Ruche, Ruche NE, and Tortue discoveries drilled previously based on 3D seismic. The well location will be southwest of the HIBM-1 exploratory well drilled by Arco in 1991 using 2D seismic, which delivered oil in core samples with dipmeter data indicating a higher structure to the southwest.
After development drilling, a further exploration well should follow in early 2020, possibly on Prospect B to the south – a large Dentale closure – or the Espadon prospect to the north of Ruche NE, which has closure at Gamba and Dentale levels.
Depending on the results from the Phase 2 wells and reprocessing, more exploration drilling could occur later in 2020.
Tullow Oil has confirmed its plans to exercise a 10% back-in right into the Dussafu license and has agreed to pay a portion of back costs. Following completion, Panoro’s interest in the Dussafu Marin license will be 7.5%.
