Asset Overview

The Crawford field is located in the Northern North Sea approximately 300 km north east of Aberdeen in water depth around 385 ft. The field lies 27 km north of East Brae and 20 km south of Harding within Block 9/28a.

Background & Exploration History

The Crawford field was originally developed by Hamilton Brothers in 1989 via the Floating Production Unit TW58. Production started in April 1989 and ceased in December 1990 with cumulative oil production of 3.9 MMbbl from 200MMbbl recognised to be in place. This initial Crawford development focused on production from the Jurassic Hugin Formation with only 0.73 MMbbl production from the Triassic reservoir. It was abandoned in 1991 in accordance with statutory regulations.

The Group acquired an initial 33.5 per cent. interest in Crawford in November 2005 from Acorn Oil & Gas Limited (‘‘AOGL’’) and increased its stake to 52 per cent. in October 2006 when it bought a further interest from Petrofac. Fairfield took over operatorship in July 2007.

Following detailed geological studies and remapping of all the available seismic, Fairfield drilled the 9/28a-18 appraisal well in 2007 and successfully proved the northern extension of the Triassic reservoir finding an oil column of over 400 ft. with pressure data showing no depletion from the previous production in the south of the field. This well also made a discovery, now called Porter, in the Early Tertiary Eocene Sele Formation.

In June 2011 Fairfield completed a farm out agreement with EnQuest PLC for UKCS Block 9/28a, which contains the Crawford oil field and the 9/28a -18 Porter oil discovery.  EnQuest acquired a 32% interest from Fairfield in return for carrying Fairfield for certain development costs up to a maximum of £34.85 million.  EnQuest’s combined working interest has increased to 51% and EnQuest has become the operator. The Joint Venture is presently focused on moving Crawford, Porter and the Jurassic Hugin Formation to project sanction.
