It was reported in the Press in early March 2018 that OKEA has found a farm-in partner for PL 038 D which contains the Grevling oil discovery. It is understood that the new, as yet unnamed partner will take a 30% stake in PL 038 D. As a result of the deal it is likely that the development concept selection and FID will be made later in 2018, with potential first oil for Grevling possible in 2021. The NPD quotes estimated recoverable reserves at 30 MMbo.  OKEA acquired its first interest (30%) in Grevling from Aker BP in 2016. It then took Repsolâs 40% and operatorship in 2017. Grevling was discovered in 2009 by 15/12-21 which encountered 67 m of net pay in the Middle Jurassic Hugin and Sleipner formations and the Upper Triassic Skagerrak Formation. Two DSTs were performed, flowing at a rate of 780 bo/d from the Sleipner and Skagerrak formations and 472 bo/d from the Hugin Formation (through a 20/64" choke). The OWC was not penetrated so a sidetrack (15/12-21 A) was drilled in a down-dip location to the east. This well confirmed oil in the same formations with a total of 36 m of net pay but the OWC was still not found. Appraisal well 15/12-23 was drilled in 2010 and found the OWC (or an ODT) at 3,251 m. The Hugin Formation was absent and the reservoir comprised just the Sleipner and Skagerrak formations which tested at a rate of 648 bo/d through a 16/64" choke. Sidetrack 15/12-23 A deviated to the west and found water-wet Hugin sands (with oil shows) and oil-bearing Sleipner sands (it TDâd in the Sleipner).  Interest in PL 038 D is currently divided between OKEA AS (70% + operator) and Petoro AS (30%).  Â  Â 
OKEA (->40% op, Petoro 30%) has found a farm-in partner for PL 038 D which contains the Grevling oil discovery. It is understood that the new, as yet unnamed partner will take a 30% stake in PL 038 D.
