Appl. No.:

17/846807

Inventors:

- Houston TX, US
Charles C. Mosher - Houston TX, US
Frank D. Janiszewski - Houston TX, US
Laurence S. Williams - Houston TX, US

International Classification:

G01V 1/36
G01V 1/38

Abstract:

Method for acquiring seismic data is described. The method includes determining a non-uniform optimal sampling design that includes a compressive sensing sampling grid. Placing a plurality of source lines or receiver lines at a non-uniform optimal line interval. Placing a plurality of receivers or nodes at a non-uniform optimal receiver interval. Towing a plurality of streamers attached to a vessel, wherein the plurality of streamers is spaced apart at non-uniform optimal intervals based on the compressive sensing sampling grid. Firing a plurality of shots from one or more seismic sources at non-uniform optimal shot intervals. Acquiring seismic data via the plurality of receivers or nodes.
