Patent ID: 7784544

Claim:
A method for treating a subterranean formation penetrated by a wellbore, the method comprising: a. predicting a plurality of formation treatment scenarios for a treatment fluid comprising a polymer and a crosslinker using a fluid rheology model comprising: i. inputting a concentration of polymer and a concentration of crosslinker, ii. inputting temperature, formation pressure, and shear rate profiles over the course of the treatment, iii. determining a concentration of crosslinks over the course of the treatment based upon the input values from i. and ii, and iv. determining the fluid rheology over the course of the treatment based on the concentration of crosslinks over the course of the treatment; b. selecting a treatment scenario from the plurality of formation treatment scenarios which provides fluid rheology properties during the course of treatment; c. preparing and injecting the treatment fluid into the wellbore; and, d. treating the subterranean formation.
