The company and its partners expect to complete pre-stack depth migration soon of two offshore 3D seismic surveys in the north of block 98/11 acquired during 1992 and 1999.
Their work has focused on the undeveloped Colter, Old Harry, and Ballard Point discoveries. Colter, the largest of the three, is within a fault block immediately south of the onshore/offshoreWytch Farm oil field operated by Perenco.
In 1989, a well on Colter drilled by Gas Council (Exploration) encountered a 10.5-m (34.5-ft) vertical oil column in the Sherwood sandstone with an oil/water contact at a depth of 1,739 m (5,705 ft) subsea. Reservoir quality is similar to Wytch Farm’s.
The partners are also close to securing permits to acquire 2D seismic over the Purbeck prospect. InfraStrata has planning permission to drill the California Quarry-1 well from onshore to offshore within the license, but not until August at the earliest.
The license carries a commitment to drill a well by February 2016. However, due to the time needed to complete the 2D survey and subsequent interpretation, the partners plan to apply for an extension of the timeframe.
They still aim to drill the well later in 2016.
