WGP in Snorre & Grane Combined PRM

WGP continues to operate Statoil’s Dual Portable Modular Source System (D-PMSS), designed and built by WGP and mobilised on the ‘Siddis Sailor’, on the third Permanent Reservoir Monitoring (PRM) survey in the North Sea.


Survey 3 is the first where Grane and Snorre fields will be shot consecutively, a total of 5,760 sail kilometres, using the D-PMSS’ dual array, flip-flop, with 25 metre shot interval.

Both surveys require close pass operations taking advantage of the mobilised vessel’s familiarity with the fields.

Additional surveys were completed on two other Statoil oil fields in between survey 2 and 3 this year, demonstrating the versatility of the portable solution. Repeat surveys are contracted until earliest 2018.
