a system for drilling a well comprises a tubular member having a bottomhole assembly at a bottom end thereof disposed in a wellbore . a first sensor is disposed in the bottomhole assembly at a predetermined axial location for detecting bending in a first axis and generating a first bending signal in response thereto , where the first axis is substantially orthogonal to a longitudinal axis of the bottomhole assembly . a second sensor is disposed in the bottomhole assembly at the predetermined axial location for detecting bending in a second axis and generating a second bending signal in response thereto , where the second axis is substantially orthogonal to the longitudinal axis . a processor receives the first bending signal and the second bending signal and relates the first bending signal and the second bending signal to a borehole curvature according to programmed instructions .
