Burgate’s strategy is to focus on acquiring discovered gas fields which have been ignored by the majors, but which are close to existing infrastructure. With new technology such as hydraulic fracturing, extended reach drilling and modern seismic processing technology these assets have substantial potential value.
The Ronaldsway gas field was discovered in 1990 by well 110/9a-2 drilled by British Gas. The field is a large dip and fault bounded structure of Permian Collyhurst Sandstone.The Collyhurst Reservoir is sealed by overlying St Bees Evaporite strata comprising halite, dolomite and shales. The contingent resources are in the range 200 to 600 bcf of dry gas with a most likely 450 bcf in the mid case.
