STABILITY MECHANISMS

CATION
EXCHANGE

This exchange mechanism between an inhibitive cation and the sodium ion on reactive clay minerals prevents swelling and subsequent shale sloughing.

SHALE
ENCAPSULATION

Reactive clays and shales are coated with polymers to prevent hydration/dispersion.

PHYSICAL
PLUGGING

This specially formulated blend mixes easily into the mud system. Unlike similar products, it has a large range of particle sizes that physically plug micro-fractures and porous zones.
