DRILFREE lubricant reduces torque, drag and the potential for differential sticking by reducing the coefficient of friction of water‐base muds. DRILFREE lubricant reduces the risk of differential sticking by lowering the filtercake thickness, reducing the coefficient of friction (COF) of the filtercake, and minimizing the yield strength of the cake. It can also provide additional wellbore stability and inhibition, reduce bit balling, and improve high‐temperature filtration control.
