Abstract
The article analyzes the effect of the limiting shear gradient of viscoplastic oil on the results of interpretation of well testing by the pressure recovery curve (PRC) method following the methods of stimulation by hydraulic fracturing. The lack of mobile water in the collector was analyzed. An analysis of the effect of the limiting shear gradient on the pressure build-up curve and interpretation results was conducted. According to the results of interpretation by the pressure recovery curve method in the presence of a limiting shear gradient in oil, curves were constructed for various dependences and deviations were revealed.
