High performance water-based lubricant and anti-sticking additive
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 filter cake thickness, reducing the coefficient of friction (COF) of the filter cake, 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.
DRILFREE lubricant is recommended for situations where torque, drag, and the tendency for differential sticking are present, such as highly deviated holes or high‐differential‐pressure wells. It is resistant to contamination and is compatible with all water‐base systems except lime muds.
