Abstract
A method of controlling a seismic vehicle may include estimating at least one orientation parameter for the seismic vehicle and controlling at least one operating parameter in view of the estimated orientation parameter(s). In non-limiting arrangements, the control may relate to re-positioning the seismic vehicle, adjusting value of a hold-down force or target drive force, and/or updating a seismic data acquisition database.
Claims14
A method of controlling a seismic vehicle, comprising:
- determining a range of values for at least one orientation parameter for the seismic vehicle;
- positioning the seismic vehicle at a location in a geographical area of interest;
- measuring the at least one orientation parameter of the seismic vehicle;
- and
- imparting seismic energy into a subsurface formation using the seismic vehicle only if the measured at least one orientation parameter is within the determined range of values for the at least one orientation parameter.

A method of controlling a seismic vehicle, comprising:
- positioning the seismic vehicle at a location in a geographical area of interest;
- measuring at least one orientation parameter of the seismic vehicle;
- and
- selecting a value of a hold-down force based on the measured at least one orientation parameter.
1 more element
A method of performing a seismic survey, comprising:
- imparting seismic energy into a subsurface formation using a seismic vehicle;
- detecting seismic signals using at least one sensor, wherein the seismic signals are reflections of the imparted seismic energy;
- and
- characterizing the surface or subsurface formation using the detected seismic signals and at least one of:
- (i) an orientation parameter associated with the seismic vehicle, and (ii) a hold-down force applied by the seismic vehicle while the seismic energy was imparted.
