Deflocculant (Modified Chrome Tannin) Supplier and Manufacturer

DEFLOCCULANT (MODIFIED CHROME TANNIN)

Deflocculant is a proprietary tannin-based product used for rheology control in water-based muds. It is readily soluble over a wide range of temperatures and is effective in low concentrations without requiring the use of caustic soda.

CHARACTERISTICS AND PROPERTY

 
Application    Required Materials
Low pH Deflocculant system    1 to 4 ppb 
(3 to 11 kg/m3) 
depending on MBT & mud weight
Defoamer in salt muds    .1 to.25 ppb
(.3 to.79 kg/m3)
Top hole and low solids, semi-dispersed muds    .1 to .5 ppb Deflocculant (.3 to 2 kg/m3)
Supplement lignosulfonate, lignite muds    Ratio of 4 lignosulfonate or lignite to 1 Deflocculant
Deep, hot drilling where lignosulfonates degrade    Ratio of 4 lignite to 1 Deflocculant
Saturated salt, inhibited or contaminated muds    .25 to 3 ppb (.7 to 9 kg/m3)
Conditioning drilling mud for packer mud (any density)    .5 to 3 ppb (2 to 9 kg/m3) for shear strength control
Cement preflush    2 to 3 ppb (6 to 9 kg/m3)

MUD TYPES


Most water-based mud formulations

MIXING REQUIREMENTS


Mix through hopper 

ADVANTAGES


Maximum deflocculation and shear strength reduction at low concentrations
4 to 8 times more effective than lignosulfonates, depending on conditions
Soluble in systems of high salinity, high hardness and at any pH
Scavenges oxygen and inhibits corrosion
High-temperature rheology control; proven effective in excess of 4000F (2040C)
Solution pH is 8.5± - no caustic needed to activate
Reduces the effects of cement contamination
