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.

FreeCable four-component analysis: An interpretation workflow of real data in complex marine and subsurface environment" by Eric Bathellier and Michel Manin.
In this technical paper, It was shown that the analysis of the propagation direction of a diffracted wave allows to interpret its generator to be a seafloor irregularity.
