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. Production at Columbus has been steady in the first half of 2025, averaging 1,500 boepd (H1 2024: 1,800 boepd) net to Serica. Annual maintenance on the host Shearwater platform began on 12 July 2025 and is scheduled to take 45 days.
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.
