Basic Info.
Product Description
(1) properties:
* copolymer of cationic monomer& acrylamide
* for carbonate reservoir( acid/rock reaction)
* viscosifying effectively to 20%hcl & 25%hcl.
* good temperature & shear resistance, can be used in acid system of 180? reservoir.
(2) characteristics:
--good rheological & thermal stability
a: 0.8%dc-4099+20%hcl gel system is for 140-160?reservoir. viscosity can reach to 40-60mpa.s under 25?/170 s-1condition, 30-35mpa.s under 90?/170 s-1,and 20-30mpa.s under 120?/170 s-1 condition.(as per chart 1)
b: 1.0%dc-4099+20%hcl gel system is for 160-180?reservoir. viscosity can reach to 50-70mpa.s under 25?/170 s-1condition, 45-50 mpa.s under 120?/170 s-1,and 20-30mpa.s under 160?/170 s-1 condition.(as per chart 2)

--good retarding performance
test showed that the retarding rate of 0.8% dc-4099+20%hcl high-temp. gel is more than 90% compared with white acid
--excellent fluid loss reducing property
dc-4099 high temperature gel is of perfect rheological function, effectively reduces the formation of fluid loss.
-- superior performance and compatibility
it can mix with inhibitor, demulsifier, iron ion stabilizer, anti-swelling agent, soluble to water or acid.
