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

Figure 7

Effect of shear thickening behavior on pressure derivative with different skin factors during falloff tests. ( is the skin factor to represent the degree of the near-wellbore damage. Pressure derivative computed by our model and the model that ignores the shear thickening behavior of the HPAM solution. 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.)
