Numerical investigation of two-phase fluid flow in a perforation tunnel

The reservoir productivity index depends on the performance of fluid flow through the perforation tunnels. Experimentally, it is observed that higher fluid flow rate occurs in perforation by drilling (PD) technique than the traditional shooting technique. This behavior is favorable for the increased hydrocarbon production from a formation. The better understanding of formation damage mechanisms for various reservoir conditions can be optimized for the economic benefits and managerial decision. The perforation by drilling technique is proposed as an alternative perforation technique since this technique induces less formation damage. Experimental and numerical investigations are ongoing research in this regards. The primary results of the two-phase fluid flow through a perforation tunnel of porous media are modeled using ANSYS CFX-15.07 platform. The numerical data are validated with the experimental data. The effects of different petro-physical properties such as permeability, porosity, fluid viscosity, flow rates, and injection pressure are analyzed in the simulations.
