Reducing infill requirements using Fresnel zone binning and steerable streamers
David J. Monk · 2010
Typically, most conventional marine 3D seismic surveys are acquired with infill to ensure adequate subsurface seismic reflection coverage in areas where seismic surveys may have been affected by adverse currents, sub-optimal streamer feather angle matching or source/streamer separations. For a typical 3D seismic survey, infill shooting may be as much as 25% or more of the total cost of prime seismic acquisition. By combining the use of an alternative method for assessing coverage with the use of the lateral control steerable streamer systems, it is possible to reduce infill to at least single digit figures for some surveys where considerably more infill was anticipated.
