Heather Formation News

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.

Proven recoverable volumes are 50-80 million barrels of oil equivalent, with the bulk of the resources occupying the Tarbert formation in the upper Brent group. Oil and gas were found in this structure, while gas was also proven in Upper Jurassic reservoir rocks belonging to the Heather formation. “We’ve had great success with exploration close to producing fields over the past year…
