Tiof-5 Appraisal Well Spudded Offshore Mauritania

Merou-1 Exploration Well – PSC B
The Merou-1 Exploration well was plugged and abandoned and the Stena Tay drill rig then moved to the Tiof-5 location.

Tiof-5 Appraisal Well – PSC B
The Tiof-5 appraisal well was spudded by the Stena Tay. The well has been drilled to a depth of 2,159 meters and the 13 5/8 inch casing set. The Tiof-5 well is located approximately 2.7 kilometers east of the Tiof-1 discovery well. Water depth is 993 meters and the planned total depth of the well is approximately 2,975 meters.

The Tiof-5 well is intended to further appraise the Tiof oil discovery and will evaluate the Miocene channel sand system within the Tiof Field area as interpreted with 3D seismic.

Tiof-3 Appraisal Well – PSC B
The Tiof-3 has been suspended as a potential future development well and the West Navigator drill ship then moved to the Chinguetti Field.

The Chinguetti development drilling program will now commence, as scheduled, to ensure adequate time to drill, complete and prepare the wells for connection to the floating, production, storage and offtake (FPSO) vessel when it arrives. The West Navigator will commence operations and subsequently be joined by the Stena Tay. The Chinguetti development well surface locations are clustered at three separate "drilling centers" allowing both rigs to work in the field at the same time. The rigs will work in tandem on the drilling centers with the West Navigator drilling and casing the top holes, followed by the Stena Tay drilling and casing the bottom holes through the reservoir interval. The West Navigator will then return to conduct the completion operations of these Chinguetti development wells after carrying out other appraisal and/or exploration activities for the joint venture.
