PRODUCTS TECHNICAL DATA
PRODUCT NAME :Zirconium crosslinking agent,ME-XICR
COMPOSITION / INFORMATION ON INGREDIENTS AND APPLICATIONS
Zirconium crosslinking agent,ME-XICR is compatible with CO2 when used with selected buffering agents. Carbon dioxide may be added to provide compatibility with formation fluids and to help recover fracturing fluids following the treatment.
Zirconium crosslinking agent,ME-XICR is a colorless to yellow uniform liquid with the property of delaying crosslinking. It is a delayed-crosslinked gelled fracturing fluid for use in wells with bottomhole temperatures between 80°F and 275°F. The fluid incorporates a low-residue CMHPG gelling agent.
It can crosslink with various plant gum thickeners, such as guar gum, hydroxypropyl guar gum, field gum, fenugreen gum, etc., to form a gel with good viscoelasticity.
The gel has the characteristics of temperature resistance, shear resistance and small filtration loss, which can meet the needs of fracturing operation in low permeability formation above 140 ℃.
The composition can be used for cross-linking organic polymers over a wide range of pH. By varying the composition and optionally adding a delay agent, the composition provides flexibility in rate of cross-linking. Further disclosed are methods to use the composition in oil field applications for hydraulic fracturing and plugging of permeable zones and leaks in subterranean formations.
Appearance: Colorless viscous liquid.
Recommended dosage: 0.7%
