In terms of sand fracturing, we not only provide cost-effective organic boron cross-linked guar gum fracturing fluid (OPTiFrac) that is suitable for most hydraulic fracturing, but also develop and commercialize nitrogen foam fracturing fluid (E-Frac) to increase the production of low-pressure oil and gas reservoirs or water sensitive reservoirs; Our developed high-temperature organic zirconium crosslinked fracturing fluid (EZFrac) can be applied to reservoirs at 190 ° C; The surfactant fracturing fluid (SurFrac) we developed reduces the frictional resistance of the liquid and greatly reduces the damage of liquid residue to the proppant, thereby maximizing the production after fracturing.
