Abstract
A marine source element is configured to generate seismic waves. The source element includes a body and a source actuator attached to the body and configured to generate the seismic waves. The body is autonomous from a vessel towing streamers along a pre-plot line associated with a seismic survey.
Claims20
A marine seismic acquisition system for collecting seismic data, the system comprising:
- plural source elements deployed at predetermined locations and configured to generate seismic waves with frequencies between 0.5 and 5 Hz;
- a vessel that advances along a pre-plot line;
- and
- plural streamers attached to the vessel and including seismic sensors for collecting the seismic data generated by detecting the seismic waves,
- wherein the source elements are autonomous from the vessel, not towed while seismic data is collected.
