Moray Firth/Witch Ground Graben
19 August 2019

Vertical appraisal well located centrally on West Wick discovery to confirm reserves and deliverability of Upper Captain Sandstone reservoir to support development decision as tie-back to Captain Field. Key objectives to acquire core and representative oil samples for viscosity (reservoir/development modelling). In main hole Sola claystones overlay Lower Captain (with residual shows below contact) with Upper Captain absent. Sidetrack offset 300 ft to east also encountered Upper Captain absent due to erosion in broad channel. Three thin hydrocarbon sands in Lower Captain. No cores/samples in either well.
