Field Developments

RWE Dea UK has interests in further gas and gas condensate development projects: Breagh, Clipper South, Devenick, Kepler and Orca. The Breagh field is located in the Southern North Sea in Blocks 42/13a and 42/12a, 65km from the north-east coast of England and around 86km from RWE Dea UK's Cavendish gas field. The resources of Breagh gas field, together with its surrounding fields, constitute probably one of the largest undeveloped natural gas discoveries in the Southern North Sea. The field development is expected to start in 2010 with production start in 2012. Estimated net reserves are substantial and will have a significant impact on RWE Dea’s total gas resources, with further upside potential identified in the surrounding exploration blocks. In 2009, RWE Dea took a 50% interest and operatorship of Southern North Sea Blocks 48/19a, 48/19c and 48/20a, in which the Clipper South field is located. The field lies in the Sole Pit Basin with a producing horizon in Rotliegendes tight-gas sands. Development of the field will rely on production from hydraulically multi-fractured horizontal wells with production start also anticipated in 2012. The Devenick field is a High Pressure High Temperature (HPHT) gas condensate project in the Central North Sea operated by BP. Development planning commenced in 2009 with production expected from an initial two subsea wells, tied-back to the East Brae facilities. RWE Dea expects the field to be on stream also in 2012. The Orca field, operated by Gaz de France Suez, is anticipated to comprise a subsea development tie-back to the D15 facilities in the Dutch sector of the Southern North Sea.
