Premier Oil anticipates to spud the Bagpuss well on 7 July, located in the UKCS Block 13/24c on the Halibut Horst, in the UK North Sea, according to partner North Sea Energy.
An option has been exercised for the Ocean Valiant semisubmersible rig to drill the well.
Premier’s analysis of the 1981 discovery well result suggests that the Bagpuss and the nearby Blofeld heavy oil prospects together could contain up to 2 billion bbl in place.
The expected duration of Bagpuss is estimated at 26 days with an additional four days for logging and sampling in the success case. The well is to be drilled to approximately 1550ft subsurface to evaluate the prospectively of the Lower Cretaceous interval beneath the Chalk and above the granite basement.
NSE’s costs relating to the initial Bagpuss well, including well planning and the site survey continue to be carried by Maersk Oil North Sea UK. The company is funded through its farm-in agreement with Maersk Oil for 100% of NSE’s costs, subject to a cap, to drill the initial Bagpuss prospect well including a site survey and 50% of NSE’s costs, subject to a cap, on a Bagpuss subsequent well, should one be drilled.
Premier Oil is the operator of the Bagpuss prospect with 40.1% interest. Partners include Maersk Oil (25%), North Sea Energy (15%), EnCounter (13.27%) and Groliffe (6.63%).
