TGS has deployed a pioneering sparse ocean bottom node (OBN) survey in the Atlantic Margin off the coast of mid Norway.
TGS has deployed a pioneering sparse ocean bottom node (OBN) survey in the Atlantic Margin off the coast of mid Norway. This initial study phase is providing proof of concept ahead of further survey proposals to highlight hydrocarbon potential in the region.
The OBN survey, in collaboration with Polarcus, has been deployed to coincide with the acquisition of the TGS AM20 seismic survey at the same location to enhance efficiencies and combine the recorded OBN data with conventional 3D streamer data to improve imaging of sediments below complex volcanic deposits.
TGS is conducting similar surveys in the Gulf of Mexico, namely Amendment and Engagement. Fast track results from last year’s Amendment sparse node programme have already provided impressive imaging uplift and enhanced velocity accuracy, especially when combined with TGS’ proprietary Dynamic-Matching Full Wave Inversion (DM FWI) technology, said TGS.
