Method of accurately determining positions of deployed seismic geophones
First Claim
1. A method of determining the location of a geophone used in a land-based seismic survey comprising:
- deploying a geophone having a unique identification code into the earth;
recording the unique identification code of the deployed geophone; and
obtaining the position at which the geophone is deployed into the earth using at least one navigational satellite receiver.

Abstract
A method is provided for accurately determining the physical location of a deployed seismic geophone used in seismic investigations by using a portable navigational satellite receiver to obtain a set of navigational satellite measurements providing the position of the deployed geophone at the time of deployment of the geophone into the earth. A method is provided for automatically and accurately identifying and determining the physical location of a deployed geophone used in seismic investigations by using one or more portable navigational satellite receivers and an automatic geophone identification and tracking system at the time of geophone deployment.
