Product Description

Product Description

SHARKSTAR^® N additive is non-ionic starch derivative used to reduce fluid loss specially designed for reservoir drilling up to 250°F.  It is commonly used conjunction with sized calcium carbonate forming a thin, easily removed filter cake, facilitating cleanup during completion, thus with minimal damage to reservoir. It is effective in both monovalent and divalent brines. Compared to PAC and other drilling starch additives, SHARKSTAR^® N can increase Low-Shearing Rate viscosity (LSRV) generating a more perfect rheology.

Applications/Functions

• Used in drill-in fluid for reservoir section
• Provides a thin, easily removed filter cake, facilitating cleanup during completion
• Increases Low-Shearing Rate viscosity (LSRV)

Advantages

• Stable at temperature up to 250°F
• Minimal damage to reservoir
• Suitable in most brines including KCl, NaCl, NaBr, CaBr₂ and CaCl₂ brine

Typical Properties

• Appearance: White fine powder
• Specific gravity: 1.5
• Solubility in water: 100%

Recommended Treatment

• A typical treatment range is 4-10 ppb 

Package

• 25 KG SACK
