Production Analysis on the Wells with Re-crosslinking of Fracturing Fluid Flowbacked

The viscosity of fracturing fluid should be very low for flowback, and it has been taken as a rule for several decades.It is interesting to find that, for some wells in the Zhongyuan Oilfield of SINOPEC, , the wells flowbacked with very high viscocity, or recrosslinked, have superior production response.the case stuies were analysed, and something beneath the viscosity should be researched.
