ConocoPhillips' interests in the East Irish Sea include the Rivers terminal at Barrow-in-Furness and five operated gas fields.  Net production in 2010 averaged 61 MMCFD of natural gas.

Millom and Dalton

Operator: HRL.
Ownership: ConocoPhillips 100.0%.
Sweet natural gas is produced from the Millom and Dalton fields through a platform and two subsea manifolds. The gas is fed through to the Morecambe Bay North terminal via the DDPA platform, where it is co-mingled with HRL's gas.

CALDER, DARWEN AND CROSSENS

Operator: HRL.
Ownership: ConocoPhillips 100.0%.
Calder has been developed with an unmanned platform and three development wells. The field produces sour gas. It feeds to a producing platform then through a pipeline to the Rivers terminal, which provides compression, hydrogen sulphide removal and metering. Options for the additional sour gas fields of Darwen and Crossens feeding into Rivers Terminal will be considered once the Calder Field begins to decline.
