Austrian energy group OMV and its partners have started oil and gas production on the Gudrun platform in the Norwegian North Sea, OMV said on Monday.
The company said Gudrun was expected to produce in a range of 35 million to 45 million barrels of oil equivalent for OMV, which acquired a 24 percent interest in a major deal with Norway's Statoil last year.
OMV added that the production start was on time and below the cost estimate in the plan for development and operation.
Operator Statoil holds 51 percent in Gudrun and GDF Suez has 25 percent.
