Abstract

Recognizing different types of risks in development of oil and gas industry can help investors and companies that wish to be active in this area. The main reason for lack of success of many investing companies in the development of oil and gas fields is lack of proper and correct understanding of risks classification and rate of their importance. Due to the wide range of input data of different risks and diversity of inputs, fuzzy logic and functions should be used in an expert system. Therefore, a comprehensive model was introduced in this study for risk assessment in health, safety, and environment (HSE) area in Pars oil and gas company through an extensive literature review and asking question from experts in this area. In this regard, after the identification of the relevant dimensions and indices, since the traditional scales cannot provide accurate and proper assessment of quality in uncertainty conditions, we made these indices fuzzy. Finally, the fuzzy expert system was designed by MATLAB software.
