Cement Additives

Our advanced liquid and dry cementing latices enhance several key cementing properties, allowing for simpler slurry designs. These additives can be used across a wide range of design densities to extend the slurry, enhance stability, control fluid loss, and mitigate gas migration.

For Dispersants

Modifies and adjusts the rheological properties of the cement slurry to help ensure proper placement in the annulus of the wellbore. Our polycarboxylate-type dispersants are highly efficient and compatible with all common cementing additives.


For Gas Migration Control

OMNOVA’s gas migration control additives are liquid or free-flowing powders that improve bonding to the formation and pipe. These products aid in maintaining a full column of cement and offer excellent free-water control, minimizing annular gas migration.


For Mechanical Improvement

OMNOVA’s flexible expanding cements help ensure well integrity by resisting stresses encountered throughout the well lifecycle. Unlike conventional cement systems, Veriflex cement expands after setting, improving cement bonding and blocking hydrocarbon migration. Its low Young’s modulus allows it to absorb cement sheath stresses without cracking. This reduces the risk of annular pressure buildup, sustained casing pressure (SCP), mechanical well damage, cement sheath failure, collapsed casing, tensile cracks, cement debonding, and costly remedial cementing jobs.


For Retarders

Adjusting the thickening time of the cement slurry is critical to operations at elevated temperatures. Our retarders are developed to work in particular temperature ranges providing a predictable, linear response of thickening time.
