Abstract
This study presents a simplified method to predict inflow performance of and cumulative production from selectively perforated wells in bounded reservoirs. The model first calculates the pseudo-skin for a fully perforated well penetrating a formation with only unit thickness. Then, perforation pseudo-skin is superimposed on a two-dimensional selectively open completed well model. Using the new model, a sensitivity study is carried out to identify the parameters controlling the well flow rate and total recovery. The sensitivity study includes the impact of shot density, perforation size and length, phasing angle, perforated length/formation thickness ratio, and the degree of formation damage around the wellbore and perforations.
