Organophilic clay for oil drilling purposes CP-250A
CP-250A is an easy dispersing and self-activating organoclay (organic modified bentonite), designed especially for use in oil drilling mud. It can be used in different base oil for drilling fuild. Especially,it is suitable for diesel oil, low aromatic mineral oil, synthetic oil and white oil.
It is valuable in low-shear mud plant operations and during completion fluid manufacture at the well site. CP-250A also possesses good low temperature incorporation properties.
Properties
Composition Organic derivative of a montmorillonite clay
Appearance Off white powder
Density 1.4kg/l
Viscosity(3% in diesel oil,600rpm) ≥50cp
Fineness (200 mesh) ≥95%
Moisture content ≤3.5%
Advantages
Suitable Solvent
Using
In oil drilling mud, it can be added directly in powder and mixed with oil. Addition level should be confirmed by testing but normally 20%-25% less than conventional organoclay. In fully oil muds, small dosage of water (0.1%-0.2%) is helpful for gelling and achieving better performance.
