Tullow Oil made an oil discovery in the Zaedyus exploratory well (GM-ES-1) offshore French Guina. The well encountered 236 feet (72 meters) of net oil pay in two turbidite fans.
Drilling results, wire line logs and samples of reservoir fluids show that the well found good-quality reservoir sands on prognosis. The well, situated in a water depth of 10,000 feet (3,048 meters), reached a depth of 18,737 feet (5,711 meters). Exploratory drilling will continue, and the well will deepen to a depth of 19,685 feet (6,000 meters) to calibrate the deeper geology. Tullow will then likely sidetrack the well to allow cores to be obtained over the reservoir sections. Drilling operations are being performed in the Guyane Maritime license using the ENSCO 8503 semisub.
The Zaedyus discovery unlocks a new hydrocarbon basin within several neighboring prospects that were mapped, so the operator will now consider performing an appraisal program and an extensive follow-up with exploration activities.
The Guyane Maritime License is operated by Tullow with a 27.5% interest. Partners on the license include Shell (45%), Total (25%), and Northpet (2.5%).
