Abstract
A method for estimating dogleg severity includes rotating the downhole tool in a wellbore. The downhole tool includes a roll stabilized sensor housing deployed in a rotating collar. The collar includes at least first and second magnets deployed thereon. Cross-axial magnetic field measurements are made using a magnetic field sensor deployed in the sensor housing while the collar rotates. A distortion is identified in the magnetic field measurements. The dogleg severity is estimated from the distortion.
