MARINE SURVEYS CONDUCTED WITH MULTIPLE SOURCE ARRAYS

摘要

Marine surveys carried out with multiple source arrays comprising three or more sources are discussed. Each source of a multiple source array is an array of source elements, such as air guns. The sources of a multiple source array may be arranged in particular type of configuration that is effectively maintained while the survey vessel travels a sail line. The sources of the multiple source array are activated to acoustically illuminate a subterranean formation with acoustic signals. Two or more sources of a multiple source array may be activated to create blended seismic data.

主权项

1. A method of collecting seismic data in a marine survey, the method comprising:
towing a multiple source array by a survey vessel, the multiple source array having three or more sources in a linear arrangement; activating the three or more sources of the multiple source array, each source producing a source wavefield; and recording seismic data generated by receivers located along streamers in a non-transitory computer-readable medium, each receiver measuring source wavefields created by the multiple source array and reflected wavefields generated by a subterranean formation in response to the source wavefields.
