Abstract:
The present disclosure relates to systems and methods for treating subterranean formations. An embodiment of the present disclosure is a method comprising: introducing a fluid comprising an aqueous base fluid and a friction reducer into a wellbore penetrating at least a portion of a subterranean formation at a pressure sufficient to create or enhance one or more fractures within the subterranean formation; recovering at least a portion of the fluid from the wellbore; adding a reactive agent to a sample of the portion of the fluid that has been recovered from the wellbore, wherein the reactive agent reacts with the friction reducer to form a photo-detectable compound in the sample; measuring a light absorbance of the sample of the fluid that has been recovered from the wellbore at a selected wavelength of light; and using the measured absorbance and a calibration curve for the selected wavelength of light to determine the concentration of the friction reducer in the fluid that has been recovered from the wellbore.

Claim (Index 16):
A method comprising:\n introducing a fluid comprising an aqueous base fluid and a friction reducer comprising polyacrylamide into a wellbore penetrating at least a portion of a subterranean formation at a pressure sufficient to create or enhance one or more fractures within the subterranean formation; recovering at least a portion of the fluid from the wellbore; adding a reactive agent comprising diisobutylphenoxyethoxyethyl dimethylbenzylammonium chloride solution to a sample of the portion of the fluid that has been recovered from the wellbore, wherein the reactive agent reacts with the friction reducer to form a photo-detectable compound in the sample; measuring a light absorbance of the sample of the fluid that has been recovered from the wellbore at a selected wavelength of light; and using the measured absorbance and the calibration curve for the selected wavelength of light to determine the concentration of the friction reducer in the fluid that has been recovered from the wellbore.
