Manufactured with a PAO synthetic hydrocarbon base, C-Mul is formulated to improve the rate of penetration (ROP), hole/shale stability and inhibition. The use of PAOs in drilling fluid additives earned patents as an innovation for synthetics in the petroleum industry.  C-Mul is designed to be added directly to water-based fluids with a minimal amount of mixing and agitation. C-Mul is compatible with fresh and saltwater systems and has no adverse effect on the LC₅₀ value of the system. C-Mul coats the formation and metal parts with a hydrophobic barrier layer of PAO minimizing balling and wear.

C-Mul with its unique rheological profile has remarkably improved lubricity in several types of drilling fluid systems including deepwater applications. The product reduces torque and drag, effectively improving drilling rates, while not adversely affecting the rheological properties of the drilling fluid system.
