Abstract
Methods and devices for sensing operating conditions associated with downhole, non-drilling operations, including, fishing and retrieval operations as well as underreaming or casing cutting operations and the like. A condition sensing device is used to measure downhole operating parameters, including, for example, torque, tension, compression, direction of rotation and rate of rotation. The operating parameter information is then used to perform the downhole operation more effectively.
