Temple Wood prospect. Deep HPHT play with Galley Sandstone objective on hanging-wall closure against Old Red Sandstone of Rattray High and dip-closure to north from 16,026–18,378 ft (LCC). Gas/condensate play with estimated pre-drill P50 reserves of 148 mmbbl oil equivalent. COS 42% with reservoir presence/quality the key risks. Well, deviated slightly to NNW, encountered gas/condensate saturation in low-porosity/permeability Intra-Kimmeridgian aged siltstone from 16,209–16,311 ft TVDSS (probable Galley equivalent) overlying Rattray tuffaceous claystones. Rattray was 1,342 ft high to prognosis with Piper secondary objective absent. No samples acquired.
