Tarbert core analysis from well 211/23b-12 shows an average horizontal permeability of 2020.8mD, with 84.75% of the sand registering above 1000mD permeability. The average porosity is 24% with 96.7% of the core porosity between 21-30%.

The Tarbert sandstone is the primary reservoir discovered in well 211/23b-12 (Skye). Surrounding analogues all around the East Shetland Basin show production from world class Brent reservoirs. Skye Summary Well 211/23b-12 was drilled in a down-dip, structural location by Hess in 1994 providing high quality core, log and RFT data. Current interpretation suggests a proven hydrocarbon column of 17.2m with a DST with sustained flow rate of 4771bbl/d, and no water production. Skye
