METHOD AND APPARATUS FOR RESCALING MEASUREMENTS WHILE DRILLING IN DIFFERENT ENVIRONMENTS
First Claim
1. A method of using a survey system comprising at least one sensor, the method comprising:
- operating the survey system to provide information regarding the orientation of the sensor relative to the Earth at a first resolution level while the sensor is a first distance relative to the Earth'"'"'s surface; and
operating the survey system to provide information regarding the orientation of the sensor relative to the Earth at a second resolution level while the sensor is a second distance relative to the Earth'"'"'s surface, the second distance larger than the first distance, the second resolution level higher than the first resolution level.

Abstract
A method of using a survey system comprising at least one sensor. The method comprises operating the survey system to provide information regarding the orientation of the sensor relative to the Earth at a first resolution level while the sensor is a first distance relative to the Earth'"'"'s surface and operating the survey system to provide information regarding the orientation of the sensor relative to the Earth at a second resolution level while the sensor is a second distance relative to the Earth'"'"'s surface. The second distance is larger than the first distance. The second resolution level is higher than the first resolution level.

11. A drilling system comprising:
-
a drilling tool; and
a survey system configured to be operable to provide information regarding the orientation of the drilling tool relative to the Earth at a plurality of resolution levels, the survey system comprising;
at least one sensor within the drilling system, the sensor configured to provide information regarding the orientation of the drilling tool relative to the Earth; and
a controller coupled to the sensor, the controller configured to operate to provide information regarding the orientation of the drilling tool relative to the Earth at a first resolution level when the drilling tool is in a first position or orientation relative to the Earth and to operate to provide information regarding the orientation of the drilling tool relative to the Earth at a second resolution level when the drilling tool is in a second position or direction relative to the Earth, the second resolution level greater than the first resolution level. - View Dependent Claims (12, 13, 14, 15, 16, 17)
