Product Description

Product Description

POLYCAP^® HP shale stabilizer is a high-molecular-weight PHPA copolymer used to encapsulate cuttings and performs as shale stability enhancer, viscosifier, flocculant, bit balling reducer and fluid loss control agent. POLYCAP^® HP rapidly adsorbs on water-wet solids to form a protective and lubricating film. This absorbed layer of polymer also contributes to filtration control. It is applicable with soft dispersive shales as well as areas with hard brittle shales. POLYCAP^® HP can be used in freshwater, seawater and monovalent brines systems. pH value of drilling fluids should be maintained in the range of 8.5-10.5 when use POLYCAP^® HP to achieve optimum results.

Applications/Functions

• Stabilizes water-sensitive formations and prevent bit balling
• Used as effective sweep for periodic hole cleaning
• Increases the yield of bentonite in low solids drilling system
• Flocculants drill solids at low concentrations

Advantages

• Stable at temperature up to 300°F
• Excellent cuttings encapsulation to prevent cuttings dispersion
• Improves the lubricity of most mud systems, particularly non-dispersed muds
• Non-fermenting and no biocide required
• Effective at low concentrations

Typical Properties

• Appearance: White powder; Specific gravity: 1.25-1.35

Recommended Treatment

• A typical range is 0.25-2 ppb. It must be added slowly through the hopper to avoid "fish eyes" generated

Package

• 25 KG SACK
