Spirit Energy spudded exploration well 43/12a-3 in licence P2128 targeting the Andromeda North prospect on 29 July 2019. The prospect had a Carboniferous objective. The company used the Noble Hans Deul (J/U) for drilling operations. On 6 November 2019 it was confirmed that operations had finished and the rig had left location. On 2 December 2019 partner HALO announced that the well encountered gas within the targeted Carboniferous sandstones. HALO stated that the well found a significant gas column within the Westphalian A target section on the north side of the Pegasus West bounding fault. The gas-water contact is shallower than Pegasus West indicating that Andromeda North is not in communication with Pegasus West. The next step for the partners will be to look at a potential appraisal well on the discovery alongside the development work which is ongoing within the Greater Pegasus Area.   The prospect is located immediately west of the Pegasus field. The Greater Pegasus Area is comprised of discoveries such as Pegasus West and Browney and also hosts opportunities like Andromeda North. Spirit Energy is moving towards a development plan for the area. Licence P2128 comprises of just the one block 43/12 which covers an area of approximately 240 sq km. The licence was awarded in the 27th Offshore Licensing Round.   Interest in the licence is held by Spirit Energy Resources (55% + operator) and HALO Offshore UK Limited (45%).
