  • Interest surges in seafloor node seismic systems


    P. Fischer

    Four component cabled seafloor seismic systems have been around for about a decade. They will continue to provide cost-effective data acquisition, especially when multicomponent data is essential. However, increasingly, operators and contractors are asking, “Why not eliminate the cable?” But, with little or no field experience, judgment, logic, and just plain faith become the tools to choose the best seafloor system for a given application, as well as the right level of R&D investment. Will operators see enough value in autonomous node systems to foster their development, even to the point of overlapping existing ocean bottom cable systems? Numerous tradeoffs in efficiency and cost immediately become evident. The raw technical tools have been around for several years, but ingenious designs and bold commitments by management will be needed to bring them to full commerciality. And what happens if, after much investment and development, operators just don't feel the value is there? Developing new seismic systems is not for the timid, but it sure is interesting.
