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.

Defoamers

Our anti-foam additives decrease foaming during the mixing process, improving the accuracy of slurry measurements. Veri-Cem defoamer additives can be used in a broad range of slurry designs and densities and do not affect thickening time.


Fluid Loss Control

Our additives are powder or liquid cement fluid loss agents that provide outstanding performance with repeatable results. These water soluble polymers minimize formation damage in sensitive zones and help mitigate lost circulation issues while cementing.


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.


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.


Retarders

Improving predictability of thickening time is critical to a successful cement job. Our retarders demonstrate a predictable linear response of thickening time. These additives disperse easily and do not adversely affect fluid loss.
