ABSTRACT:
A method for generating corrected geologic depth information is disclosed. The method includes: estimating a depth of each of a plurality of different locations along a length of a drillstring disposed in a borehole; measuring at least one environmental factor at each of the plurality of different locations and determining a deformation of the drillstring at each of the plurality of different locations from the measured environmental factor; and generating a non-linear model of the deformation along the length relative to a reference point. A system and computer program product for generating corrected geologic depth information is also disclosed.
