Patent ID: 8738293

Claim:
An apparatus for estimating a property of an earth formation, the apparatus comprising: a carrier configured to be deployed according to a selected position relative to the formation, the carrier including at least one sensor array, the at least one sensor array including a plurality of sensors configured to estimate at least one property, each of the plurality of sensors located at a known position relative to one another; and a processor in operable communication with the plurality of sensors and configured to estimate uncertainties of the location of the plurality of sensors based on a plurality of sequential time-lapse measurements from each of the plurality of sensors, the plurality of sequential time-lapse measurements including a first measurement from at least two of the plurality of sensors at a first time at which the carrier is deployed according to the selected position and a second measurement from the at least two of the plurality of sensors at a later time at which the carrier is deployed according to the same selected position.
