Comprehensive Decision-Making Criteria for Determination of Optimal Gas Monetization Strategy Using Fuzzy Delphi Method

The development and exploitation of the countrychr('39')s gas fields requires huge investments that will require appropriate monetization strategies to offset these costs and generate revenue for the government. This study describes the most important gas monetization strategies, including pipeline, LNG, GTL, petrochemical, CNG, GTW and GTS, and emphasizes the need for utilize the appropriate strategies for each field. What is important in comparing and selecting these strategies for Iranchr('39')s gas fields is to adopt a large-scale, multi-dimensional approach and multi-criteria decision-making approaches that require the identification of criteria that are important to experts and decision-makers. Therefore, 19 criteria including multiple components in technical, economic and commercial, environmental, political and market areas were extracted through literature review and have been basis for questionnaire preparation. Then, using the single-stage fuzzy Delphi method, participantschr('39') opinions about the importance of these criteria were obtained and with the help of screening threshold, four criteria were removed and 15 criteria were identified. Criterion products market earned the highest score and criterion alignment with government policies earned the lowest score.
