Paper Title:
Design of Gas Injection Unit in an Iranian Onshore Oil Field Development Project
  Abstract

In an Iranian oilfield development which is under construction nowadays, it is decided to inject the separated gas in the reservoir Instead of flaring it. For this reason the injection pressure is calculated about 520 bars. The maximum rate of injection will be 280 millions cubic feet per day (330 363.215 cubic meter/hour). This gas should be injected in the reservoir to increase its pressure but the most important thing here is the injection compressor configuration. 3 units has been considered to compress the gas and each unit had 100 MMSCFD capacity. For increasing the gas pressure two compression units are foreseen: flash unit and injection unit. In flash gas unit the pressure will increase from 6 bars to 75 bars and in injection unit from 75 bars to 525 bars. But the gas which is upgraded in the flash unit should be dehydrated in dehydration package before entering to the injection unit. Due to the high flow rate of injection and other reasons which are discussed in this paper, the compressors are selected from centrifugal types. It is shown that in both flash and injection units, the compressors should be considered multistage. By the injection of associated gas instead of flaring it, the environment can be prevented from pollution and the reservoir pressure always will be maintained in a desired level. (Abstract)
