Method for seismic surveying using wider lateral spacing between sources to improve efficiency

摘要

Abstract [00421 A method for towing a marine seismic acquisition array in a body of water includes towing a plurality of laterally spaced apart sensor streamers behind a survey vessel in the water. A lateral spacing between adjacent streamers is represented by L. At least two laterally spaced apart seismic energy sources are towed behind the survey vessel. A lateral spacing between the at least two sources is represented by kL, wherein k is a constant and wherein k is at most equal to the number of streamers. -12 19 19 } 16 18 20A 18 16 14 20A 24 24 24 20A 14 24 20 20 20A 20 20 24 22 22 29 29 22 22 23 29 23 23 29 23 29 29 29 29 22 22 22 22 26 26 26 26 26A 26A 26A 26A 22 22 22 22 29 29 29 29 22 22 22 22 26 26 26 26 26A 26A 26A 26A 22 22 22 22 23 23 23 23 29 29 29 29 22 22 22 22 25 25 25 25
