Engie E&P Norge has awarded Schlumberger’s WesternGeco two contracts for acquisition and processing of towed 4D seismic data in the production license 153, the Gjøa license, in the northern part of the Norwegian North Sea.
The acquisition will be performed with the vessel “WesternGeco Magellan”, and is planned to be completed by the beginning of August.
The planned seismic survey is a repetition of a 3D survey acquired over the Engie E&P operated Gjøa field ten years ago.
“The main objective for the repeat survey this summer is to observe production effects on the Gjøa field and contribute to an optimised field management strategy,” says Asset Manager for the Gjøa field Hilde Ådland in Engie E&P Norge.
The Gjøa field is currently the fifth largest producing field on the Norwegian Continental Shelf, according to the Norwegian Petroleum Directorate.
WesternGeco has been awarded the 4D towed acquisition contract with planned mobilization offshore Florø on the western coast of Norway in the beginning of July 2017.
In addition, WesternGeco has been awarded the processing of the 4D data, with expected startup mid-august and planned completion in the first quarter 2018.
The processing will be performed at WesternGeco’s facility in Tananger, close to Stavanger in Norway.
“The 4D seismic will increase our understanding of the Gjøa reservoir and may help identify potential undrained compartments,” Ådland said.
Gjøa is located 60 kilometers west of Florø in Sogn og Fjordane on the west coast of Norway, and is operated with power from shore.
