The Effect of Rheology of Viscoelastic Polymer on Pressure Transient Response in Near-Wellbore Regions

Figure 9

Effect of shear thickening behavior on pressure derivative with different injection rates during falloff tests. The solid line is the pressure derivative computed by our model. The dash line is the pressure derivative computed by the model that ignores the shear thickening behavior of the HPAM solution.
