Details:
Carboxymethyl hydroxypropyl guar Gum (CMHPG) is double chemical modified guar gum by carboxymethyl hydroxypropyl ether which is specially designed for oilfield industry as additives for water and methanol-based fracturing fluids. Three types of CMHPG guar gum are manufactured and used in oilfield industry: CMHPG I and II, fast hydration CMHPG.
Aqueous fluids system contained CMHPG I is used in hydraulic fracturing process for drilling of deeper wells and high temperature oil and gas wells. These applications are mainly due to the CMHPG's excellent capabilities of increasing viscosity, reducing fluid loss and decreasing fluid friction. In these systems, crosslinking procedure can be delayed until the fracturing fluid enter into oil and gas reservoir which significantly reduce the required pumping pressure. Carboxymethyl hydroxypropyl guar also produces less “residue after break” during the hydraulic fracturing process.
CMHPG II is a new-type product which can crosslink with metal ion and get more stable gel resistant to high temperature and shear. Under the same formation conditions, CMHPG II requires lower concentration of dosing and its water insoluble is accordingly less. CMHPG guar damage to the fracture conductivity and the metrical permeability is also smaller. At the same time, the fracturing fluid has strong carrying capacity, good viscoelasticity, low friction and low concentrations for gel breaking and it is easy for flowback. These features make CMHPG II play a very important role in the fracking high-temperature wells and unconventional reservoirs which meet the exploitation needs of current unconventional oil and gas.
Fast hydration CMHPG (FH-HPG) can achieve high viscosity without any buffer systems and can release its 90% viscosity immediately within 3 minutes. FH-HPG has excellent capabilities of hydrating faster, reducing insoluble material, improving temperature stability, widening chemical compatibility and gel breaking. Bichain is one of reliable guar gum suppliers and manufacturers in CMHPG, Carboxymethyl hydroxypropyl guar gum for fracking oil & shale gas wells at competitive CMHPG guar gum powder prices.
Technical Data:
CMHPG guar spec
Package:
25 kg net weight with trinity paper-plastic compound bag or 900 kg, 1000 kg jumbo bag.
Shelf life: 12 months
Usage Method:
Put CMHPG I into stirring water, and add acid to adjust PH to 5-7, sequentially with agitation, viscosity will be released quickly.
Put CMHPG II, FH-HPG into water with rapid agitation, adding at the point of fastest agitation, viscosity will be released quickly without adjusting Ph value.
