Shale stability is primarily aected by the swelling of clay minerals in the wellbore, and it is one of the main issues in drilling operations. The stability of clay-rich shales is aected by their complex physical and chemical interactions with drilling uids. It is known that shale – uid interactions can be manipulated to enhance cuttings and wellbore stabilization as well as improving hole-making ability in shale formations.

CS OILFIELD made an extensive work for years to evaluate and nd solutions to mitigate and control the interaction of drilling uids and clay-rich formations while protecting the environment. Our clay control solutions have signicant advances and show excellent results in problematic shale formations around the world. We oer specialty products to provide the most ecient clay control solutions.

POLYAMINE

POLYAMINE shale inhibitor reduce the interlayer space of hydrated clay to prevent swelling and hydrations. Their chemical structure reduces hydration repulsion, which lowers clays hydration tendency as per the clay structure.

DRILL CAP X

Acrylamide copolymer with relatively lower molecular weight. Specially designed to provide high encapsulation to eliminate shale dispersion without causing excessive rheology.

Q-DRILL

Special blend of surface-active agents formulated to increase the Rate of Penetration (ROP) by reducing the accretion on the bit.
