Additives which destroy foam or prevent foam formation in water-based drilling fluids to assure an accurate specific gravity.

Drilling Systems

Improve well economics and performance with fewer products and easier wellsite transportation costs. Pexostart high performance water-based fluid system combines the key ingredients into one product, allowing for simple enhancement and improved performance.

Lost Circulation Materials

OMNOVA's lost circulation materials (LCM) are environmentally preferred and can be applied through the drill string into any fracture to create a strong bridge across the loss zone. This unique process can be applied with the rig equipment to place the slurry inside the fracture and then perform a squeeze to begin the dewatering process. Pexoplug LCM products can cure losses instantly without time or temperature dependency.

Shale Inhibitors

OMNOVA's shale inhibitors inhibit water transfer into shale formations resulting in a more stable wellbore. Our complete line of products mitigate reactive formation swelling, avoiding stuck pipe and non-productive time.


Reducing torque and drag not only accelerates rates of penetration (ROP), but also increases bit and tool life. Pexolube lubricants can be used for both water-based and emulsion fluids to enhance ROP, reduce friction, and help prevent bit "balling."
