Abstract:
1. A method for towing a marine seismic acquisition array in a body of water, comprising: towing a plurality of laterally spaced apart sensor streamers behind a survey vessel in the water, a lateral spacing between adjacent streamers represented by L; towing at least two laterally spaced apart seismic energy sources behind the survey vessel, a lateral spacing between the at least two source represented by kL, wherein k is a constant and wherein k is at most equal to the number of streamers; and steering the sensor streamers to have a selected spread angle between a first portion of the streamers extending behind the survey vessel and a second portion of the streamers extending behind the survey vessel, the first and second portions comprising entire streamers laterally displaced on opposed sides of a sail line of the survey vessel and using seismic data from overlapping common depth point lines acquired laterally between the lateral positions of the sources to reduce infill acquisition.
