RWE Dea Norge AS, operator of production licence (PL)420, is completing drilling operations on appraisal well 35/9-11-S and sidetrack 35/9-11-A on the Titan discovery, 16 kilometres west of the Gjøa Field in the North Sea. The purpose of the well was to delineate the Titan discovery towards the south and to reduce the uncertainties in reservoir thicknesses and reservoir properties. With the appraisal well, oil was proven in the Heather Formation, the Brent Group, the Drake Formation, the Cook Formation and the Statfjord Formation. RWE Dea Norge carried out extensive data collection and sampling of the reservoir, including five so-called mini-DSTs.
