Abstract
An apparatus is described whereby the side force on a drill bit can be measured during drilling operations and transmitted to the surface where it can be used in predicting trajectory of the hole and taking corrective action in the drilling operation. A downhole assembly using a downhole motor is modified to include means to detect the side thrust or force on a bit driven by the motor and the force on the deflection means of the downhole motor. These measured forces are transmitted to the surface of the earth during drilling operations and are used in evaluating and controlling drilling operations. Means are also provided to measure magnitude of the force on a downhole stabilizer.
