The Columbus Development is located in the UK Central North Sea and produces from a gas-condensate reservoir in the Forties Sandstone Formation. The development consists of a single horizontal well which runs along the central axis of the reservoir, drilled in the spring of 2021, and production commenced in November 2021. During the first half of 2024, Columbus production was steady, averaging 1,800 boepd net to Serica in H1. Following maintenance in Q3, which resulted in no production in that quarter, production resumed in October, averaging 2,000 boe/d in Q4 and 1,400 boe/d for 2024 as a whole.

The Columbus well is connected to the Arran export pipeline through which Columbus production is exported along with Arran Field production.  When production reaches the Shearwater platform, it is separated into gas and condensate.  The gas is exported to St Fergus via the SEGAL line and the condensate to Cruden Bay via the Forties Pipeline System.
