LONDON -- The jackup Ensco 80 has started drilling the Conan exploration well in the UK East Irish Sea for Serica Energy.
Conan is a Triassic Sherwood Sand gas prospect identified on 3D seismic, covering an area of up to 28 sq km (10.8 sq mi) in blocks 113/26b and 113/27c. Serica believes it is the largest undrilled Sherwood Sand seismic anomaly in the eastern Irish Sea.
It is also close to the producing Millom gas field and the recent Rhyl gas discovery. If the current well delivers commercial gas, Conan could be developed relatively quickly through existing infrastructure.
Following a farm-out announced in January, Serica retains a 65% interest in Conan with Agora Oil and Gas paying 70% of the well costs, in return for a 35% interest in the structure.
The well will be drilled to 5,000 ft (1,524 m) and should take 24 days to drill.
