Equinor has awarded PGS and Shearwater GeoServices framework agreements for 4D towed streamer seismic acquisition on the Norwegian continental shelf (NCS). The agreements have a total estimated value of 700 million kroner.
PGS and Shearwater have been awarded generic framework agreements covering 4D seismic services on the NCS for a firm period of 2 years starting in 2021. The agreements include two two-year options and can also be applied for the UK continental shelf.
“4D seismic gives us better data to map remaining oil and gas resources as the reservoirs are being produced. These contracts will help us optimize the reservoir drainage and place new wells, and thereby achieve our ambition of recovering 60% of oil and 85% of gas on the NCS,” said Charlotte Bøe Tjølsen, vice-president of petroleum technology operations, Equinor.
PGS has also been awarded a specific framework agreement for 4D seismic services at Gullfaks field. The agreement comprises an exclusive right to acquire up to three surveys prior to 2031.
PGS is scheduled to acquire two 4D GeoStreamer monitoring surveys in 2021 over Fram and Tordis-Vigdis fields. The first survey is scheduled to start in June 2021, and the total duration for the two 2021 projects is estimated at 2.5 months.
Under the frame agreement, Shearwater has been awarded an initial survey over Heidrun field in the Norwegian North Sea.
Shearwater will allocate one of its high-end Isometrix vessels for the 1-month Heidrun survey, which starts in this year’s second quarter.
The offshore operations will be supported by PGS’s office in Oslo and Shearwater’s offices in Bergen and Gatwick.
