Impact of Perforating on Well Performance and Cumulative Production

摘要: 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 fully well penetrating formation with only unit thickness. Then, perforation is superimposed on two-dimensional open completed model. Using new model, sensitivity carried out identify parameters controlling flow rate total recovery. includes impact shot density, size length, phasing angle, length/formation thickness ratio, degree damage around wellbore perforations.
