- Clay inhibitor and fixative for polymer based drilling,
completion, and workover fluids
- Highly soluble in water
DESCRIPTION
Cl Free is a solution of multivalent,
non-volatile organic amine in water. Packaging is in 5 gal
plastic containers.
APPLICATION
Cl Free is an effective clay inhibitor
for water sensitive formations. Cl
Free has a small radius of hydration and is easily
substituted on the exchange sites for the sodium ion, thereby
effectively blocking the site for water hydration. Cl Free is designed to be used at pH values of
10.5, or less.
FEATURES
- Excellent biodegradability (>60% by DOC Method)
- Chloride free
- Non-oil wetting
- Non-foaming
- Essentially non-toxic (includes oral toxicity, dermal toxicity,
and aquatic toxicity)
- Small ionic radius
- Strongly cationic
- Equipment in standard mud kit can test for residual amine
concentrations
MIXING INSTRUCTIONS
Normal concentrations range from 0.3 to 3% by volume depending
upon the application.
