East Midlands Basin Fields
Hatfield Moors and Hatfield West are two small gas fields with GIIP of 6.1 BCF and 2.4 BCF, respectively on adjacent licences PL161-3 and PL 162-2, east of Doncaster in South Yorkshire, England, operated and wholly owned by Edinburgh Oil & Gas plc.
This paper describes the accidental discovery of the Hatfield Moors Gas Field and its subsequent development and eventual utilization for gas storage, the first such project onshore UK. The nearby Hatfield West Field is also described. The two fields are located on adjacent faulted anticlinal structures in the NW part of the Gainsborough half-graben. The reservoir for both fields is the Westphalian B Oaks Rock sandstone. Reservoir quality is excellent.
A gas storage project was agreed with Scottish Power in 1998. Two horizontal wells, Hatfield Moors-5 (1998) and Hatfield Moors-5z (1999) have been drilled for the project by Edinburgh Oil & Gas plc using innovative drilling techniques. Since 1999 gas has been imported from the Transco network and exported from the reservoir according to market demands under the terms of the gas storage contract.
