The Cod oil gas and condensate field was a gas and associated natural gas liquids (NGL) production field in the Norwegian sector of the central

North Sea The North Sea lies between Great Britain, Denmark, Norway, Germany, the Netherlands, Belgium, and France. A sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Se ...

. Production of oil and gas started in 1977, peak gas and NGL was achieved in 1980. Production ceased in 1998 and the field installation was dismantled in 2013.

The field

The characteristics of the Cod field reservoir were as follows.

Owner and operator

The field was owned and operated by ConocoPhillips Skandinavia AS.

Infrastructure

The Cod field was developed through an offshore installation.

Production

The design production capacity of Cod was 17,400 bopd (barrels of oil per day) and 117 mmscfd (million standard cubic feet per day) of gas. Initial separation was at 500 psia (88.3 bar). There was a single 3-phase separator with provision for 350 bpd of produce water. The produced gas was dried in a glycol contactor. Condensate was dried in coalescing filters. Dehydrated oil and gas streams were combined and sent to Ekofisk in a single 2-phase pipeline. Cod also received gas from the Ulla field which passed directly to the export pipeline. Production from the Cod field was by natural depletion. The oil, natural gas liquids (NGL) and gas production profile of the Cod field is as shown.

Cod production profile

Cod ceased production in 1998 and the installation was removed from the field in 2013.###nor
