RI 5608 Computer Programs For Tarner Calculations Of Gas-Drive Oil Recovery By Analytical Or Iterative Method ? Summary And Introduction

In a recent report3/ the authors presented a rapid method of calculating, by means of a desk calculator, the future performance of oil reservoirs in which the motivating agent was gas. The accuracy of the method was tested by data obtained from an electronic computer. Because of the accuracy obtained for the limited number of calculations performed, considerable interest has been expressed in the electronic computer program used to obtain the comparative data by an analytical solution. Accordingly, the computer procedures for the analytical solution are presented in this report. In an earlier report, 4/ a reservoir appraisal procedure was published in which an iterative method was used. Many requests were received for the computer program used to obtain the values given in that paper. That program, with some modifications, also is presented in this report. The modifications are given because of the progress that his been made in computers, and because much of the program for the analytical solution is usable for the iterative procedure.
