INVESTIGATE TECHNO-ECONOMICAL ASPECTS OF PRESSURE BOOSTING STATIONS TO ENHANCE OIL EXTRACTION IN GACHSARAN

Abstract

The purpose of this study is to consider strategies and options for improving the efficiency of the pressure boosting station No. 4 in Gachsaran oil reserve (which is located in south-western of Iran). In order to achieve these objectives, the four rational options from technical and operational views were proposed and then these options went through an economic assessment. Next, by onsidering the other important criteria based on technical conditions (due to the necessity of evaluating other criteria beside economic criterion), decisionmaking techniques were employed. The results of economic evaluation show that the present value of the costs of option 1 is lower than other options and option 2 provides poorer economic status and is ranked last among the recommended options. Therefore, option 1 is 30.5 percent better than option 2. In addition, employing MCDM Technique allocated maximum weight (0.320) to economic evaluation criterion and again option 1 -with the highest weight (0.354)- was the best possible option. Regards to purpose of this study, using techno-economical approach leads practitioners to decide based on technical and economic facts simultaneously.
