Abstract
To determine a position of a survey receiver used to measure a response of a subterranean structure to a survey signal, positions of the survey receiver as the survey receiver descends in a body of water to a surface are received from an acoustic ranging system. Measurement information associated with movement of the survey receiver is received from at least one sensor. Based on the measurement information from the acoustic ranging system and the at least one sensor, the position of the survey receiver at the surface once the survey receiver has reached the surface is computed.
Claims21
A method of determining a position of a survey receiver used to measure a response of a subterranean structure to a survey signal, comprising:
- receiving, from an acoustic ranging system, positions of the survey receiver as the survey receiver descends in a body of water to a surface;
- receiving, from at least one sensor, measurement information associated with movement of the survey receiver;
- and
- computing, based on measurement information from the acoustic ranging system and the at least one sensor, the position of the survey receiver at the surface once the survey receiver has reached the surface.
A system comprising:
- a plurality of different types of measurement devices to measure a position of a survey receiver in a body of water, wherein the survey receiver is used to measure a response of a subterranean structure to a survey signal;
- and
- a processor to:
- combine the measurement information from the plurality of different types of measurement devices to determine a position of the survey receiver once the survey receiver reaches a water bottom surface.
An article comprising at least one computer-readable storage medium containing instructions that when executed cause a processor to:
- receive, from an acoustic ranging system, positions of the survey receiver as the survey receiver descends in a body of water to a surface;
- receive, from at least one sensor, measurement information associated with movement of the survey receiver;
- and
- compute, based on measurement information from the acoustic ranging system and the at least one sensor, the position of the survey receiver at the surface once the survey receiver has reached the surface.
