The present disclosure generally relates to the use of a self-propelled underwater vehicle for seismic data acquisition. The self-propelled underwater vehicle is adapted to gather seismic data from the seafloor and transmit such data to a control vessel. The self-propelled underwater vehicle may be redeployed to several seafloor locations during a seismic survey. Methods for real-time modeling of a target zone and redeployment of the self-propelled underwater vehicle based on the modeling are also described.

1. A method for surveying subterranean formations, comprising: providing at least one self-propelled underwater vehicle, the vehicle having at least one sensor disposed therein;lowering the self-propelled underwater vehicle into the sea;deploying the self-propelled underwater vehicle to a first location on the seafloor to gather seismic data via the at least one sensor, the first location having a first depth;retrieving the seismic data from the self-propelled underwater vehicle while the self-propelled underwater vehicle remains in the sea at a second depth different from the first depth, below a surface of the sea and above the seafloor; anddeploying, after the retrieving, the self-propelled underwater vehicle to a second location different from the first location and on the seafloor to further gather seismic data. 2. A method according to claim 1, wherein the at least one sensor comprises a seismic sensor, andthe method further comprises gathering seismic data with the seismic sensor. 3. A method according to claim 2, wherein the seismic sensor comprises a hydrophone, a geophone or an accelerometer, andthe method further comprises gathering seismic data with the hydrophone, geophone or accelerometer. 4. A method according to claim 1, wherein the at least one sensor comprises an electromagnetic sensor, andthe method further comprises gathering seismic data with the electromagnetic sensor. 5. A method according to claim 1, wherein the self-propelled underwater vehicle comprises a control unit, andthe method further comprises providing a surface control unit that communicates with the vehicle control unit. 6. A method according to claim 5, wherein deploying the self-propelled underwater vehicle to the first location comprises issuing positioning commands from the surface control unit to the vehicle control unit. 7. A method according to claim 1, wherein deploying the self-propelled underwater vehicle to the second location comprises issuing positioning commands from the surface control unit to the vehicle control unit. 8. A method according to claim 5, further comprising providing a control vessel that carries the surface control unit, whereinretrieving the seismic data comprises positioning the self-propelled underwater vehicle at an underwater location proximate to the control vessel. 9. A method according to claim 5, further comprising providing an autonomous sea surface vehicle that carries the surface control unit, whereinretrieving the seismic data comprises positioning the self-propelled underwater vehicle at an underwater location proximate to the autonomous sea surface vehicle. 10. A method according to claim 1, wherein providing at least one self-propelled underwater vehicle comprises providing a plurality of self-propelled underwater vehicles. 11. A method according to claim 10, further comprising redeploying the plurality of self-propelled underwater vehicles respectively to at least one additional location to gather seismic data. 12. A method according to claim 1, further comprising using the seismic data retrieved from the self-propelled underwater vehicle to update a model of the subterranean formation. 13. A method according to claim 12, wherein the second location is chosen based upon the revised model of the subterranean formation. 14. A method for performing real-time modeling of a subterranean formation, comprising: deploying at least one self-propelled underwater vehicle to a survey region on the seafloor, the self-propelled underwater vehicle having a sensor disposed therein;gathering seismic data with the sensor when the self-propelled underwater vehicle is at a first depth;retrieving the seismic data from the self-propelled underwater vehicle when the self-propelled underwater vehicle is at a second depth different from the first depth, the second depth being below a surface of the sea and above the seafloor;deploying, after the retrieving, the self-propelled underwater vehicle to a second location different from the first location and on the seafloor to further gather seismic data; andusing the seismic data to update a model of the subterranean formation. 15. A method according to claim 14, wherein the sensor comprises a seismic sensor, andthe method further comprises gathering seismic data with the seismic sensor. 16. A method according to claim 15, wherein the seismic sensor comprises a hydrophone, a geophone or an accelerometer, andthe method further comprises gathering seismic data with the hydrophone, geophone or accelerometer. 17. A method according to claim 14, wherein the sensor comprises an electromagnetic sensor, andthe method further comprises gathering seismic data with the electromagnetic sensor. 18. A method according to claim 14, wherein a drilling rig or other semi permanent sea surface facility is associated with the subterranean formation, anddeploying at least one self-propelled underwater vehicle comprises deploying at least one self-propelled underwater vehicle from the drilling rig or other semi permanent sea surface facility. 19. A method according to claim 14, wherein the model was created based on a first survey, anddeploying at least one self-propelled underwater vehicle occurs during a second survey, the second survey being separated in time from the first survey.
