The influence of ionic hydration inhibitors on dual inhibitor system mud properties – clay rock swelling

Abstract

Various organic and inorganic compounds can be used as the hydration inhibitors. The main purpose of this paper is the examination of five different ionic hydration inhibitors: $KCl$, $K_{2}CO_{3}$, $HCOOK$, $NH_{4}Cl$, $CaCl_{2}$. The paper contains survey findings of the influence of the abovementioned inhibitors different concentrations on technological parameters of drilling muds with dual inhibitor system and swelling of clays.
