7 September 2017

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 16,000–18,378 ft (LCC). Gas/condensate play with estimated pre-drill P50 reserves of 147 mmbbl oil equivalent. COS 42% with reservoir presence/quality the key risks. Well encountered possible oil saturation in low-permeability Intra-Kimmeridgian aged siltstone from 16,209–16,311 ft overlying Rattray tuffaceous claystones. Rattray was significantly high to prognosis with Galley objective absent.
