Patent number: 10450854Abstract: The present disclosure describes measuring bending moments within a drillstring or tool string to identify deflections (or “dog-legs”) within the string. In some systems, the bending moments a plurality of strain gauges. In some such systems the strain gauges will be arranged in a selected spacing around the circumference of the tool string, in many examples, at a common plane extending generally perpendicular to the longitudinal axis of the string proximate the strain gauges.
