A computer program was developed to study the effect of length and distribution of perforated intervals on horizontal wells rates. The program couples a theoretical solution of the productivity index to a multiphase flow model in the horizontal section of the well. Inflow performance curves generated with the program for horizontal wells drilled under various reservoir conditions revealed a direct dependence of well rate to perforated intervals length and distribution, with heel concentrated perforations offering the best yields compared to the toe concentrated perforation or the uniform perforation across the whole length of a well. Moreover, an optimum perforated length that yields maximum production rate was determined.
