Simulation of the Effect of Viscoelastic Diverting Acid (VDA) byUsing STIMPRO Software

Matrix acidizing operation is the simplest and main method of stimulating the well, by which thepermeability of the damaged opening of the well is improved. When acid is injected into the well, itpreferentially penetrates areas of higher permeability or undamaged areas due to lower resistance. Acidinjection, self-diverting VDA, for uniform stimulation is an effective method to divert acid to lowpermeability areas. In this article, using Stim -Pro (۲۰۱۹) software, we have compared the time withand without the use of self-diverting acid on increasing the efficiency of acidizing. In addition, thecomparison of parameters such as invasion depth, skin factor and changes in the bottomhole pressurein time with and without the use of self-diverting acid has also been done.
