Abstract
Summary This paper presents an aid in the effective design of a comprehensive optimum gas-well completion program involving the gravel-packing method of sand control to ensure maximum productivity for a long period. A numerical approach using PI as a measure of eventual well performance is used in analyzing the productivity of gravel-packed gas wells with a computer. An outline of the comprehensive equations needed to compute PI under steady- and semisteady-state flow conditions based on modified Darcy's law for gas flow is presented. The final analysis with the computer package centers on how best to design a gravel-packed gas-well program that will ensure maximum productivity.
