Moray Firth/Witch Ground Graben
16 June 2020

Appraisal/exploration well located on the crest of the Skipper heavy oil discovery with a primary target in the Intra-Beauly Skipper Sandstone and secondary exploration targets in the Lower Dornoch and Maureen. The principle objective was to acquire high quality wireline oil samples for viscosity and oil gravity. The well encountered the Skipper reservoir 44 ft high to prognosis, resulting in an increase in oil in place, but recovered samples had a lower gravity (10.5° API) and higher viscosity (12,026 cP) than anticipated. Sands were encountered in the Lower Dornoch and Maureen, but were water-wet.
