Methods for estimating wellbore gauge and dogleg severity

A method for estimating wellbore dogleg severity in a downhole tool, the method comprising:

• (a) deploying a downhole tool in a subterranean wellbore, the downhole tool including first and second tool body sections coupled to one another via a universal joint that enables relative tilting of the tool body sections, the downhole tool further including first and second axially spaced stabilizers deployed on at the corresponding first and second tool body sections;
• (b) tilting the universal joint in a first cross-axial direction such that the second tool body section is tilted in a direction of wellbore curvature and measuring a magnitude of a first tilt angle of the universal joint;
• (c) tilting the universal joint in a second cross-axial direction such that the second tool body section is tilted away from the wellbore curvature and measuring a magnitude of a second tilt angle of the universal joint;
• and
• (d) processing the magnitude of the first tilt angle measured in (b) and the magnitude of the second tilt angle measured in (c) to estimate the dogleg severity.
