Optimum Solid Fraction Based on Mud Weight

The optimum solid fraction refers to the ideal concentration of solids (including chemical additives, weighting agents, and drilling cuttings) in the mud.

The optimum Low Gravity Solids (LGS) concentration is determined based on the mud weight. It ensures wellbore stability and safe drilling deviation trajectories by considering geomechanical parameters such as Poisson’s ratio, Young’s modulus, and unconfined compressive strength.
