In one embodiment, the cross-linking agent is an organic zirconate, such as bis(hydroxyethyl)glycine zirconate. The organic zirconate is effective to cross-link the polymer when the composition is at a temperature of at least about 105° F., and a pH of about 10 or higher, preferably a pH in the range of about 10.5-12.

16/4/2020, · Water-based fracturing fluids - uncrosslinked polymers and "slickwater". A common practice in the hydraulic fracturing of gas-producing reservoirs is the use of nonviscous "slickwater" fluids pumped at high rates (,> 60bpm), to generate narrow fractures with low concentrations of proppant.

1/10/2020, · ,High-temperature, shear test was carried out on the concentration of 0.3 wt%, 0.4 wt% and 0.5 wt% guar, fracturing fluid., The test results are shown in Fig. 1 (A). When the temperature reaches 155 °C, the viscosity of 0.5 wt% guar, fracturing fluid, is still greater than 150 mPa s, and the performance of the, fracturing fluid, at that concentration meets the requirements of, high temperature fracturing.
