In June 2015 Serica completed the transaction with BP to acquire an 18% interest in the producing Erskine field lying to the south of Columbus, with the effective date of 1 January 2014. 

The Erskine field has strong synergies with Columbus, being a gas and gas condensate stream which uses the Lomond platform as export facility, one of the planned alternative export routes for Columbus production.  NSAI carried out a reserves audit on the field and estimates remaining reserves, as of end 2016 to be 3.8 mmboe net to Serica.

The field, operated by Chevron, is a High Pressure High Temperature (HPHT) gas condensate field and was originally discovered in 1981. Main reserves lie in three separate, but generally overlying, Jurassic sandstone-producing horizons.  The field has been developed with five producing wells.

The production facilities comprise a normally unmanned platform located at Erskine with production handled and controlled from the Lomond platform operated by Shell 30 km to the north.  The Lomond Platform lies 269 km east of Aberdeen, adjacent to the Columbus field.   Gas and liquids produced from Erskine are transported to the Lomond platform via a 16in nominal bore multiphase pipeline where the fluids are processed, with gas then transported via the CATS pipeline, and liquids via the Forties Pipeline System.
