Abstract
A seismic survey system includes at least one autonomously operated vehicle and at least one seismic energy source associated with the autonomously operated vehicle. The autonomously operated vehicle includes a controller programmed to operate the at least one seismic energy source at selected times and to cause the autonomously operated vehicle to follow a predetermined geodetic path.
Claims21
A seismic survey system, comprising:
- at least one autonomously operated vehicle;
- at least one marine seismic vibrator associated with the autonomously operated vehicle;
- wherein the autonomously operated vehicle includes a controller capable of operate operating the at least one marine seismic vibrator at selected times and to cause causing the autonomously operated vehicle to automatically follow a first predetermined geodetic path;
- and
- at least one seismic streamer towed by at least one of the autonomously operated vehicle and a second autonomously operated vehicle, the seismic streamer comprising at least one device selected from the group of devices comprising:
- a pressure compensation device, a lateral force and depth control device, a position sensor, and any combination thereof.

A method for seismic surveying, comprising:
- moving a first autonomously operated vehicle in a body of water automatically along a predetermined geodetic path, the autonomously operated vehicle towing a seismic streamer therefrom;
- moving one or more second autonomously operated vehicles in a selected pattern automatically with respect to the first autonomously operated vehicle and substantially simultaneously therewith, each of the second autonomously operated vehicles moving a marine seismic vibrator therewith, wherein each of the first and each second autonomously operated vehicles includes a controller capable of causing the autonomously operated vehicle to follow a predetermined geodetic path associated therewith;
- actuating the marine seismic vibrator on at least one of the second autonomously operated vehicle vehicles at selected times;
- and
- recording signals generated by seismic sensors in the seismic streamer, wherein the seismic streamer comprises at least one device selected from the group of devices comprising:
- a pressure compensation device, a lateral force and depth control device, a position sensor, and any combination thereof.

A method for seismic surveying, comprising:
- moving a plurality of autonomously operated vehicles in a body of water substantially simultaneously automatically along a corresponding plurality of predetermined geodetic paths associated therewith, each autonomously operated vehicle towing a seismic sensor streamer therefrom, each autonomously operated vehicle moving a marine seismic vibrator therewith, each autonomously operated vehicle including a controller capable of causing the autonomously operated vehicle to follow the associated predetermined geodetic path;
- actuating the marine seismic vibrator on at least one of the autonomously operated vehicle vehicles at selected times;
- and
- recording signals generated by seismic sensors in each at least one seismic sensor streamer,
- wherein each seismic streamer comprises at least one device selected from the group of devices comprising:
- a pressure compensation device, a lateral force and depth control device, a position sensor, and any combination thereof.
