Abstract
A downhole measurement assembly, tool, and method is provided. The downhole measurement assembly includes at least one drill collarhaving at least one compensation portion and at least one force portion with a load paththerethrough. The compensation portion has a different dimension from the force portion. The assembly also includes a plurality of compensation sensorspositionable about the compensation portion to measure downhole tool pressures applied thereto, and a plurality of force sensorspositionable about the force portion to measure downhole forces applied thereto. The compensation sensors and the force sensors are positionable about the drill collar(s)in a strain configuration along the load pathwhereby the measured downhole tool pressure is isolatable from the measured downhole forces on the drill collar(s).
