DOUGLAS, UK — Crogga Ltd. has appointed THREE60 Energy, formerly Fraser Well Management, to drill the Crogga Independence appraisal well (112/25a-2) on the Crogga gas field in the East Irish Sea, offshore the Isle of Man.
Crogga Ltd. expects drilling to start as soon as the permitting process has completed. Management’s aim is to establish commercial flow rates from the conventional Permian Collyhurst sandstone reservoir.
If successful, 3D seismic and further drilling would follow and could lead to one of the largest field developments in the East Irish Sea, comparable to Douglas and Hamilton in BHP’s Liverpool Bay development to the south, (661 Bcf / 110 MMboe).
The gas could provide energy independence and a significant revenue boost to the Isle of Man.
The work program, which was delayed by the COVID-19 pandemic, includes a commitment to drill two appraisal wells.
The upcoming well, which should take three months to complete, will be designed to determine the full size of the gas column and to measure the flow rate. If commercial, production could start in 2026.
Crogga Ltd. plans a subsea completion.
