Abstract
A method and system for improving cuttings measurements in drilling operations includes rotating a helical screw in a trough at a first speed, measuring a first weight of a cuttings mixture within the trough, measuring a first torque required to maintain rotation of the helical screw at the first speed through the cuttings mixture, and calculating a difference between the first torque and a second torque required to maintain rotation of the helical screw at the first speed through a second weight of natural cuttings equal to the first weight.
