Project Profile
Value: US$250 million
Location: Block 9/28a in Production License 209 in the UK sector of the North Sea
Start-up Year: 2013
Upstream Oil Reserves: 200 million barrels
Water Depth: 117m
The Crawford oil field is located on Block 9/28a in Production License 209 in the UK sector of the North Sea in waters measuring 117 meters. Crawford was discovered by Hamilton Brothers in the mid-70s and was then fully appraised by three wells. The field was developed by five wells with production commencing in 1989 by the Transworld 58 semisub.
In late 1990, Crawford was abandoned and all facilities were removed. The oil production rate at the time was 5,000 bopd with no water from the two primary reservoirs – Jurassic and Triassic – with a total production rate of only 3.9 MMbbl. When Fairfield acquired the license in 2007, the operator performed new 3D seismic data to establish a clear picture of the reservoir structure and character. The Rowan Gorilla VII drilled an appraisal well, 9/28a-18, confirming the extension of the Triassic reservoir into the northern part of the field.
It is estimated the field contains about 200 million barrels of good quality oil in several reservoirs, principally in the Triassic at around 2,743 meters deep. Fairfield is currently reviewing field development options, but is strongly considering tying the field back to the East Brae platform. Once a plan is sanctioned, further development drilling will be performed with first production targeted for late 2011. Currently, field development is on hold. Bids for a drilling rig and subsea equipment are under review but contracts will not be awarded at this time.
