Wells sometimes are kept with the injection. Therefore the evaluation of injection indices depended on material injection, seems to be necessary. This study is going to determine the drive indices for a reservoir by making a model using Eclipse. The model consists a gas cap and aquifer, in which there is an injection well used to show water drive index. The summation of reservoir drive indices is equal to one and changing in one drive index can cause changes in the other drive indices. The relation between the all exciting drives and their effects on each other were shown by changing the production conditions in the model. A second model was simulated to know the effects of gas injection process, which is used to keep pressure and production from the reservoir. The role of effective parameters, including gas oil ratio and water cut in 3000 days, were evaluated in the second model. The optimum gas injection rate and influence of drive indices in the simulated field were obtained from the results of this work.  UR - https://jchpe.ut.ac.ir/article_9958.html L1 - https://jchpe.ut.ac.ir/article_9958_31bcf745847e1390374ecc514e672fbf.pdf ER -
