Product Description

NewPHPA™ DSL shale stabilizer and encapsulator is a versatile, extremely low molecular weight, medium charge polyacrylamide designed primarily to provide shale stability and encapsulation in water-based drilling fluids. Because of its low molecular weight, it has considerably less effect on rheology than NewPHPA™ and NewPHPA™ D polyacrylamides, thereby allowing for treatment with higher concentrations. NewPHPA DSL microbeads dissolve rapidly into the system.

Benefits Benefits

Shale Inhibitor: NewPHPA DSL additive is an efficient shale encapsulator, particularly when used in combination with the potassium ion. It coats drill cuttings, thus allowing their removal through the solids control equipment before becoming dispersed in the active system.

Flocculant: NewPHPA DSL additive can be used as a flocculant in non-dispersed systems to enhance the removal of drill solids.

Lubricant: NewPHPA DSL additive reduces torque and drag.

Application Application

NewPHPA DSL shale encapsulator can be used in freshwater, seawater and sodium or potassium chloride brines. NewPHPA DSL acts primarily as a shale inhibitor. NewPHPA DSL also works as a flocculant and lubricant, although not as effectively as other NewPHPA additives.

Treatment Recommendation Treatment Recommendation

Concentrations of 1-4 lb/bbl are recommended. The microbeads should be added directly through the hopper.
