INVERT EMULSION VISCOSIFIERS

Organophilic Clays and Liquid Additives

 

AES VIS LS enhances low shear rate viscosity

Invert Emulsion Viscosifiers

Our viscosifier options provide enhanced rheological control. Whether it’s AES VIS LS to enhance low-end suspension or ENERVIS RM for a flat rheological profile, AES Drilling Fluids provides the products for superior suspension. 

Optimized Rheology

Rheological modifiers enhance fluid properties for suspension across shear rates. Additives vary by their impact on viscosity. Some will enhance low shear rate viscosity to mitigate sag while others contribute to the overall profile. Liquid additives have the ability to impart viscosity at various temperature thresholds to reduce variance in rheology across large temperature variations in the wellbore. 

Organophilic Clays

Organophilic clays are common clays, such as bentonite, that are treated to “oil-loving” materials through a chemical process. The treatment process and base clay will vary by temperature stability and performance requirements. The varieties of clays offered balance cost with performance.

AES Drilling Fluids offers two families of organophilic clays. One is designed to elevated the low shear yield point to minimize settling and sag risk. The second elevates the yield point with less impact on low shear yield point. Organophilic clays also provide supplemental filtration control and enhance emulsion stability.

Organophilic clay products are frequently used in a combination at ratios that vary by desired properties and mud weight.

Liquid Viscosifiers

Liquid additives provide viscosity by building a network around the solids present in the drilling fluid. These additives can consist of surfactants and polymers that can be used with or without organophilic clay additives. 

Liquid additives are key components of “flat” or “fragile gel” systems that change viscosity based upon the temperature.
