Affleck was discovered by Shell in 1975. The primary reservoir is Tor chalk formation with a small gas cap. The field was developed via two horizontal production wells tied back to the then Maersk-operated Janice field, 28 kilometres to the west. Oil was routed via Janice into the Norpipe pipeline, and Gas was routed via the Clyde platform and onwards to the Fulmar gas line to St Fergus. The Affleck field ceased production in May 2016 and the Affleck wells have remained closed in since then after producing a total of 4.3mmbblofoil. Work is currently ongoing to assess host options for the redevelopment of the Affleck field with a tie-back to two potential host facilities. The redevelopment would make use of the existing infrastructure still in place at Affleck.
