Shale Inhibitor HP**0

Product Description

LIQUID PHPA HP**0 is a water soluble emulsion by copolymerization for drilling fluids . Main materials are acrylamide, acrylates and its derivatives, auxiliary materials are mineral oil and surfactant. Its viscosity-average molecular weight is up to 6 million and it is mainly used to inhibit clay from hydration swelling.

Advantages

* Provides shale inhibition and limits cutting dispersion, is beneficial to prevent bit balling

* Reduces fluid loss

* High viscosity effects, maintains polymer drilling mud’s rheology

* Resistance to contamination of salt and calcium-magnesium, can be used in brine and saturate brine drilling fluid systems

* Readily dispersible, quickly soluble and does not form “fish eyes”

* Stabilizes borehole, reduces torque, improves quality of mud cake

* Passes solid equipment smoothly, high efficiency, economical

* Easy to use, convenient to add, no powder contamination

Application Range and Method

HP**0 not only has an effect on inhibiting shale from hydration, dispersion and encapsulating cuttings, but also inhibiting water sensitive formation from water swelling. It’s suitable for mud-making and water sensitive formations. Recommend to use in polymer drilling fluid systems.

HP**0 can be formulated into aqueous solution for use or mixed in drilling fluid directly. Suggest mixing uniformly and slowly or intermittently. Be careful not to add too fast, otherwise it will form a plug flow.

It should be added timely to maintain the inhibition capacity of drilling fluids. Recommend dosage is 0.4% to 0.8%.
