Product Description

Product Description

EZTHIN^® is an environmental acceptable high performance thinner used in water-based drilling fluids up to 400°F. It is modified tannin compound that replaces chrome lignosulfonates. EZTHIN^® is 4-8 times more effective than chrome lignosulfonates. It requires no caustic to activate as solution pH is approximately 8.5. EZTHIN^® can provide maximum deflocculation and shear strength reduction at low concentrations. EZTHIN^® is widely used in high salinity, high hardness, gypsum, any pH and recognized as the most cost-effective thinners for WBM.

Applications/Functions

 

• Reduces gel strength and rheology properties in both dispersed and non-dispersed WBM while maintaining hole cleaning capabilities
• Functions in fresh water, sea water, salt water and divalent brine systems
• Can effectively treat contamination from salt, cement, anhydrite, drilled solids

Advantages

 

• Temperatures stable up to 400°F
• Excellent performance at low concentrations 
• Tolerant to high salinity, high hardness, gypsum and any pH
• Contains no chrome
• Extremely cost-effective product

Typical Properties

 

• Appearance: Reddish brown powder
• Specific gravity: 0.47
• pH: 6

Recommended Treatment

 

• A typical range is 1- 4 ppb, but specific drilling conditions will dictate a suitable concentration

Package

 

• 25 KG SACK
