Introduction

THERMOTHIN® is a sulfonated styrene-maleic anhydride copolymer based (SSMA for short), low molecular weight, top-level thinner used in most water-based drilling fluids at extreme temperature conditions. THERMOTHIN® 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. THERMOTHIN® is effective over a broad pH range and in the presence of contaminants such as carbon dioxide, cement, lime or salt.

Applications/Functions

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

Advantages

• Temperatures stable up to 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
• Specific Gravity: 1.00
• pH: 12

Recommended Treatment

• The addition of 1- 3 ppb of THERMOTHIN® will normally stabilize the rheological characteristic of fluids exposed to extreme downhole temperatures

Package

• 55 GAL DRUM/CUSTOMIZED
