Abstract
A technique facilitates the use of seismic data. The technique utilizes an autonomous underwater vehicle to obtain data on water column characteristics in a seismic survey area. The data can be used to adjust aspects of the seismic survey data and/or the seismic survey technique.
Claims27
A method for facilitating seismic data acquisition, comprising:
- utilizing an autonomous underwater vehicle to obtain data on water column characteristics in a seismic survey area;
- transmitting the data to a collection location;
- and
- employing the data to correct inaccuracies of seismic data obtained during a seismic survey of the seismic survey area.
1 more element
A method, comprising:
- obtaining data in a marine survey area with an autonomous underwater vehicle;
- using the data to determine a water column characteristic at multiple locations in the marine survey area;
- and
- employing the water column characteristics to improve the usefulness of seismic data obtained during a seismic survey of the marine survey area.
1 more element
A system, comprising:
- an autonomous underwater vehicle having trajectory control features of that are adjustable to control the trajectory of the autonomous underwater vehicle when underwater, the autonomous underwater vehicle further comprising at least one detector to collect data related to sound velocity;
- and
- a processing system selectively placed in communication with the autonomous underwater vehicle to collect the data, wherein the processing system uses the data to create a map of sound velocity in a marine survey area.
A method, comprising:
- obtaining data related to characteristics of a water column in a seismic survey area with an autonomous underwater vehicle;
- and
- performing a seismic survey throughout the seismic survey area.
