West Firsby

The Company produces from three oilfields in the East Midlands – a 100% working interest in both the West Firsby and Crosby Warren fields and a 65% non-operated interest in the Whisby W4 well. Overall daily production is stable at approximately 110 barrels of oil, all of which is transported by tanker to the refinery at Immingham in NE Lincolnshire.

The West Firsby Field, which commenced production in 1991 and is 15km north of Lincoln, is the main operating base with two wells producing ~40bopd.

Monthly oil production for Crosby Warren, West Firsby and Whisby is provided to OGA (The Oil and Gas Authority) using the UK PPRS “Petroleum Production Reporting System”. Data can be viewed on the OGA website.

West Firsby provides an excellent opportunity to evaluate, test and prove the assorted technical aspects of CausewayGT’s geothermal systems. Located in the East Midlands, West Firsby is late in its productive life with nine wellbores with seven wellheads. The wellbores extend over an area of some 2.5 km2 and extend to a depth of 1,680 m. The existing well bores, together with the availability of production and data which has been collected over the last 34 years and the geothermal gradient make West Firsby a good candidate for testing geothermal solutions.
