The PEM water-base polymer mud system was developed to provide an environmentally acceptable drilling fluid that approaches the inhibitive performance of an invert oil emulsion fluid.

PEM is engineered with a specially formulated PF-JLX additive for maximum shale inhibition and designed to drill high-angle wells in reactive formations, normally reserved for an oil-base mud. The primary functions of the PF-JLX in the system are to improve shale stability and the lubricity of the fluid.
