Engie E&P Norge has awarded Schlumberger company WesternGeco two contracts for acquisition and processing of towed 4D seismic data over 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 10 years ago.
"The main objective for the repeat survey this summer is to observe production effects on the Gjøa field and contribute to an optimized field management strategy", says Asset Manager for the Gjøa field Hilde Ådland in Engie E&P Norge.
The Gjøa field is situated in one of ENgie E&P's core areas, and 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 Q1 2018. The processing will be performed at their processing facility in Tananger, close to Stavanger in Norway.
