Product Description
Fluid and petro-physical heterogeneities are encountered in most sandstone and carbonated formations. Chemical diverter technology is one of the methodologies to be used in stimulation treatment to divert treatment fluids from high water cut layers to low water cut layers, and/or from high permeability zones to low permeability zones. JKN-VES-MT is a non-damaging chemical diverter used in stimulation fluid systems to improve treatment of fluid distributions across formation matrixes to increase stimulation efficiency.
Technical & Engineering Information
JKN-VES-MT is a surfactant based chemical diverter which is very effective in distributing treatment fluid homogeneously across treatment zones in stimulation treatment at various well conditions. JKN-VES-MT forms viscous micelle structure when its concentration reaches a certain level in water or brines. Viscosity breaks dramatically when it contacts hydrocarbon or crude oils. The in-situ viscous behavior of JKN-VES-MT in aqueous solution will divert treatment fluids from high water-cut to low water-cut, from high permeability to low permeability zones of the rock matrix. The matrix is therefore stimulated homogeneously.
JKN-VES-MT is compatible with most additives in stimulation fluid systems. Some additives such as corrosion inhibitor or solvent may have adverse effect on JKN-VES-MT rheological properties. Compatibility testing is generally required when JKN-VES-MT is used in stimulation treatment.
Technical Indicators
Technical Indicators of JKN-VES-HT
Item | Indicator |
Appearance | Liquid |
Colour | Light Yellow to Light Brown |
Specific Gravity | 0.95-1.10 |

Recommended Treatment
JKN-VES-MT should be made directly into the suction tank with the agitators switched on to ensure thorough dispersion in the completion brine before displacement downhole. Treatments should be made using a chemical barrel pump to avoid splashes.
Recommended working temperature < 120˚C
Viscosity after 170S-1 sheering, cps ＞80
Packing and Storage
JKN-VES-MT is supplied in 53gallon(200L) high density polyethylene (HDPE) drums or 265gallon(1000L) IBC. Keep it away from extreme conditions such as places near flames or direct sunlight.
Shelf life: 2 years.
