Moray Firth/Witch Ground Graben
22 March 2022

Vertical appraisal well located centrally on the West Wick discovery to confirm reserves and deliverability of the Upper Captain Sandstone reservoir to support development decision as tie-back to the Captain Field. Key objectives were to acquire core and representative oil samples for viscosity (reservoir/development modelling). Sola claystones overlay Lower Captain in the main hole, with residual shows below the field oil-water contact and Upper Captain absent. Sidetrack offset 400 ft to NE also encountered Upper Captain absent due to erosion within a broad channel. Three thin hydrocarbon sands logged in the Lower Captain. No cores/samples taken in either well.
