ConocoPhillips' interests in the East Irish Sea include the Rivers terminal at Barrow-in-Furness and five gas fields.  Net production in 2011 averaged 62 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 natural 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, which produces sour gas, has been developed with an unmanned platform and three development wells.. It feeds to a producing platform then through a pipeline to the Rivers terminal at Barrow-in-Furness, England, which provides compression, hydrogen sulphide removal and metering. Options for developing the additional sour gas fields of Darwen and Crossens feeding into Rivers Terminal will be considered once the Calder Field begins to decline.
