Abstract
Wellbore tracking by developing a wellbore deviation survey, including collecting wellbore deformation data using a caliper at each of a plurality of depths within the wellbore, collecting wellbore deviation data using a tiltmeter at ones of the plurality of depths, determining simulated wellbore deformation and deviation data using the oriented wellbore deformation data, and developing a wellbore deviation survey by calibrating the wellbore deviation data based on the oriented wellbore deviation data.
