Abstract
A method and system is disclosed for automatically correcting for depth errors in measurements taken from a drillstring during the drilling phase of the construction of a hydrocarbon wellbore. The correction is based on a stress profile which in turn is based on the states of the drilling rig, drill string description length spec, borehole description trajectory, friction factor and weight on bit.
