Columbus overview


The Columbus Field is located in blocks 23/16f and 23/11a, approximately 35km northeast of the Shell-operated Shearwater Field. Columbus is a gas-condensate accumulation in the Forties sandstone formation discovered in 2006 and has been fully appraised by four wells. The Columbus FDP was sanctioned in Q4 2018 with first gas achieved in Q4 2021. The field is operated by Serica Energy. On the 8th of November 2018 Tailwind completed the acquisition of EOG’s UK business which included a 25% non-operated interest in the Columbus development project in the North Sea. 
On the 31st of October 2018, the OGA approved the Field Development Plan for Columbus which consists of a single subsea horizontal well, drilled north-to-south in the reservoir. The well was drilled by Serica and tied-back to the Shell operated Arran-Shearwater pipeline via a subsea manifold. Columbus reservoir fluids (gas and condensate) are processed on the Shearwater platform and exported to shore via existing infrastructure. Produced water is discharged at the Shearwater platform via existing facilities.  First gas was achieved on 21 Nov 2021.
