Sulfonated Styrene-Maleic Anhydride Copolymer Drilling Fluids

Product Description

Product Description

AQUATHIN^® is a sulfonated styrene-maleic anhydride copolymer based (SSMA for short), low molecular weight, high-performance thinner used in most water-based drilling fluids at extreme temperature conditions. AQUATHIN^® is actually enhanced by the unusually high temperature encountered when drilling deep wells, and has been used successfully at BHT in excess of 500°F. AQUATHIN^® is effective over a broad pH range and in the presence of contaminants such as carbon dioxide, cement, lime or salt.

Applications/Functions

• Deflocculates water-based systems at extreme downhole temperatures
• Helps minimize thermal flocculation
• Stabilizes the rheological and filtration properties of WBM at extreme temperature conditions

Advantages

• Stable at temperature above 500°F
• Compatible with other drilling additives
• Effective over a broad pH range
• Effectively treat contaminants from carbon dioxide, cement, lime or salt
• Environmentally acceptable

Typical Properties

• Appearance: Amber Liquid
• Density: 1.15-1.30 sg
• pH: 4.0-5.5 

Recommended Treatment

• The addition of 1- 6 ppb of AQUATHIN^® will normally stabilize the rheological characteristic of fluids exposed to extreme downhole temperatures

Package

• 1150KG/tote tank, IBC tank
