Tullow Oil says that the Paon-2A appraisal well in the CI-103 licence offshore Côte d'Ivoire has determined the down-dip extent of the Paon oil accumulation. The well encountered the water below the oil accumulation discovered at the Paon-1X well and pressure logging has located the likely oil water contact.
To minimise the number of appraisal wells, Paon-2A was located 15km south west and approximately 370 metres down-dip of the Autruche light oil discovery made by the Paon-1X well in 2012. The well encountered Upper Cretaceous reservoir sandstones which were water bearing at this location. Pressure data from the Autruche age reservoirs intersected in Paon-2A indicate that the Autruche oil accumulation between this well and Paon-1X has a hydrocarbon column of at least 230 metres.
