New Empirical Correlation To Predict Apparent Viscosity of Borate-Crosslinked Guar Gel In Fractures

摘要

Successful design and completion of hydraulic fracturing treat- ments depend on accurate estimation of fracturing fluid viscosity. This requires better knowledge of the fluid viscosity under in situ Conditions. The viscosity estimation is even more important for Borate-crosslinked guar gel because the gel behavior depends on Temperature, wellbore shear pre-conditioning, fracture shear rate, And fluid pH.
