document: In July 2020 Tangram Energy was still offering the opportunity for interested parties to farm-in to licence P2421 (block 211/23c) containing the 211/23b-12 (Skye) discovery and Skylark prospects. The opportunity was previously announced in December 2019. The structures are located on the Dunlin and Dunlin SW fault blocks. The Tarbert Sandstone is the primary reservoir discovered in well 211/23b-12 on Skye discovery. The well, drilled by Hess in 1994, proved high quality log and RFT data. From recent analysis, it is thought to contain a hydrocarbon column of 17.2 m and a DST undertaken achieved 4,771 b/d with no water produced. From core analysis undertaken on a core from the Tarbert sands, an average horizontal permeability of 2,020.8 mD with 84.75% of the sand registering above 1,000 mD. Average porosities of 24% were registered and 96.7% of the core porosity was between 21% to 30%. Tangram has conducted seismic interpretation, depth conversion, static modelling and reservoir studies along with petrophysical analysis. Further rock physics work is to be undertaken on the existing reservoir. STOIIP P50 volumes for Skye are 15 MMbo, for Skylark A structure they are 20.4 MMbo and for Skylark B 21.7 MMbo.     The development concept for Skye and Skylarks comprises two wells that will target both proven and up-side resources which would be tied back to existing infrastructure of a nearby hub. The acreage is located 8 km from the Causeway and Fionn fields, 11.5 km from Thistle and Deveron and 19 km from the Cormorant North infrastructure.     Interest in the licence is held solely by Tangram Energy Limited.
