This work addresses the effect of horizontal well length as well as the length and distribution of perforated intervals on horizontal well performance. A computer program based on analytical solution of the flow performance in the case of partially horizontal wells has been developed and tested against field data. After conducting an extensive number of computer runs to study the influence of the main parameters affecting the performance length fraction, the reservoir permeability and the fluid viscosity, a correlation has been developed to describe the performance of partially perforated horizontal wells by comparison to openhole wells. The results are presented in the form of a relation between the production loss due to partial perforation and friction forces and various well parameters. Another estimation is also presented to estimate the optimum horizontal well length.
