Map of Columbus field export routes

Columbus export routes.

The Columbus field is a gas-condensate accumulation in the Forties Sandstone Formation and has been fully appraised by four wells. It has been comprehensively mapped and modelled by Serica in preparation to progress the field through development and on to production.

Independent consultant Netherland, Sewell & Associates, Inc (“NSAI”) carried out a reserves audit on the Columbus field in 2017 based on a single well development. This report estimated that the gross Proved plus Probable Contingent Resources of the field are 53.8 bcf of gas and 3.7 mmbbl of liquids, a total of 12.6 mmboe.

Serica’s share of proved and probable contingent resources in the field is estimated to be 26.9 bcf of sales gas and 1.8 mmbbl of liquids, a net 6.3 mmboe to Serica.

Serica technically evaluated two alternative export routes for Columbus production, via the Chrysaor-operated Lomond platform directly southeast, or via the Shearwater platform, 35km to the Southwest as part of a joint development of the Arran field. Serica has informed the OGA that it will prepare a Field Development Plan to develop Columbus by tying a subsea well into the pipeline proposed to be laid between Arran and Shearwater.
