Vertical gas storage appraisal well located on western flank of a large Lower Triassic (Bunter Sandstone) anticline (5/42 storage site; Endurance). Objectives included coring, full wireline logging, sampling and drill stem testing of the Bunter and Rot Halite and Rot Clay caprock to assess reservoir quality and performance and cap-rock integrity to demonstrate suitability for long-term CO2 sequestration. Well encountered top Bunter at 4,490 ft TVDSS. Formation evaluation programme achieved as planned, including 630 ft core and DST flow and injection tests.
