First gas announced from North Sea's Orca field

HAMBURG, Germany --  Production from the southern North Sea's Orca gas field has started. The operator is GDF SUEZ E&P Nederland, with RWE Dea as partner.

The Orca field will be developed by drilling three wells in total. The first two development wells have been drilled and completed in 2013. The third producer is currently being drilled and is expected to be completed in February next year.

“The United Kingdom is of high strategic importance for RWE Dea and Orca is the fourth of our United Kingdom projects coming on stream within only 1.5 years,” says Dirk Warzecha, COO of RWE Dea.

The gas is located in Carboniferous reservoir and the platform D18a-A is located in the Dutch sector, 500 m from the United Kingdom sector and in 40 m water depth.

Orca is one of only two known fields to straddle the median line between the Netherlands and United Kingdom (the other being Markham). The Orca development project, which is unitised between the United Kingdom and Netherlands participants, was approved by the partners in 2011.

At Orca, the produced gas, separated from free liquid in the production separator, will be measured on the platform and transported via an 8 inch subsea pipeline, routed to the D15a-A platform 20 km north for further treatment. After treatment on the D15a-A platform, the produced gas will be transported via the existing main pipeline system, operated by Noordgastransport, to Uithuizen in the Netherlands.

Orca spreads into blocks 44/24a, 44/29b and 44/30a in the United Kingdom, while it is in blocks D15b and D18a in the Dutch sector.
