Cutting-edge marine seismic technologies — some novel approaches to acquiring 3D seismic data in a complex marine environment
First Break - Nov 2017 - Special Topics

The use of streamer or Ocean Bottom Cable (OBC) techniques for a seismic survey in a complex marine environment present major operational challenges owing to islands, large variations in water depth within a few kilometres from the shore and a complex sea floor because of canyons, pinnacles, steep reef flanks, rugose sea floor, and corals. Salt-dominated provinces, too, present a complicated geological setting — deep targets below salt layers of variable thickness, salt mounds, massive halite and anhydrite layers in the overburden, a highly rotated post-salt section, steep geological dips at the target level, and a complex fault system. Complexity of the survey area requires novel approaches and customized seismic data acquisition technologies for a cost-effective imaging solution. We present four innovative marine seismic technologies, tested to assess their efficacy in acquiring long offset wide azimuth data, in a logistically complex marine environment.
