Estimation of the maximum efficiency of injection wells for gas re-injection using the example of a field of the Gazprom neft companу group

Abstract

Introduction. The development of oil fields located in remote, hard-to-reach areas with a lack of developed infrastructure for external transportation of oil and gas is complicated by the problem of associated petroleum gas utilization. Optimizing this process requires selecting the number of injection wells and estimating the maximum injection well efficiency.
Aim. Estimation of the maximum efficiency of injection wells for the reverse injection of produced associated petroleum gas.
Materials and methods. Analysis of geological and geophysical information on the field and application of existing international experience in determining the efficiency of gas injection wells.
Results. Using the example of an oil and gas field, the approach is described, and examples of calculations for determining the maximum intake capacity of gas injection wells are given.
Conclusion. The maximum efficiency and required number of gas injection wells for utilization of the produced associated petroleum gas into the reservoir have been determined.
