In Repsolâs Q2 2020 conference call, which took place in late July 2020, the company highlighted its recent successes in the US frontier region, particularly the recent Monument discovery in deepwater Gulf of Mexico, and the Mitquq and Stirrup discoveries in Alaska. Test results from the original Mitquq 1 bored indicate further enhance prospectivity along the trend between Mitquq and the core Pikka development on the North Slope. Mitquq 1 NFW, sited on North Slope ADL 393876, encountered 16m of hydrocarbon pay in its secondary Alpine C target after being drilled to a TD of 2,472m. 10m of this is net oil pay and six metres of net gas pay. In January 2020, Mitquq 1 encountered 60m of hydrocarbon pay within the primary objective Nanushuk interval (separate from the Pikka Development Nanushuk reservoir). The well intersected 5m of net gas pay, and 55m of net oil pay. No oil-water contact was encountered.The recent Stirrup 1 discovery represents one of the highest flow rates ever achieved from a Nanushuk single-stage stimulation of a vertical well on the North Slope. The NFW, sited in North Slope ADL 392044, intersected the targeted Cretaceous Nanushuk sandstone reservoir at 1,322m - encountering 23m of net oil pay - and was subsequently fracture stimulated and flowed at a stabilised rate of 3,520 bo/d over a one-hour period, with a gas:oil ratio of 560 scf/stb and less than 14.5% water cut on a 128/64â choke. Stirrup 1 NFW was P&A'd during April 2020. The well was targeting a large Cretaceous Nanushuk sandstone structure - west of the Horseshoe discovery and south-west of the Pikka Unit, in a similar geological setting. Stirrup 1 has the potential, together with Horseshoe, to be able to underwrite a standalone development. The results from both wells will be evaluated over the remainder of 2020.
