Glycol Concentration Test In Drilling Mud
Glycol is generally used in KCl-Polymer fluid systems when enhanced Shale Inhibition is required. Glycol will be lost through adsorption on exposed shale formations in the wellbore and on the cuttings, and the glycol depletion rate will be a function of drilling Penetration Rate (ROP) and Cuttings size. The glycol concentration test in drilling mud therefore needs to be monitored to ensure that levels are maintained for effective shale inhibition.
