Licence P.099 comprises the West Lennox oil discovery and the Crosby oil/gas exploration prospect

The West Lennox field is an oil discovery located in Block UK110/14c which lies in 15 metres of water off the coast of Liverpool. The discovery well, which was drilled in 1990, encountered a 25 ft oil column in massive reservoir sandstones of the Lower Triassic Sherwood Sandstone Group. These reservoir sands are presently producing 12,000 BOPD at the BHP-Billiton operated Lennox oilfield located just 3km to the east in block UK110/15a.

110/14c-6 well

In 2005 the consortium drilled the UK110/14c-6 appraisal well on the flank of the West Lennox field.  The well was declared as having “tight hole” status by the Operator, and it remains so.

In addition to West Lennox, the consortium has an interest in neighbouring block UK110/14d, which contains the highly prospective Crosby oil/gas exploration prospect (potential recoverable reserves 15 MMBOE).

The partners were recently awarded the adjoining part blocks 110/9b, 110/14b in the UK 24th Round, which includes the Dee exploration lead.
