Abstract
Exploitation centers have a vital role not only in the oil and gas industry but also in many other industries, and are considered one of the most important export factors in the country's income generation. However, heavy crude oil exploitation and refining operations have seen significant transformations due to product changes to meet market demand and environmental regulations. In this study, a fuzzy network model has been designed to evaluate the efficiency of the country's oil and gas exploitation centers based on undesirable outputs in the oil exploitation centers of Khuzestan province. In this research, to evaluate the effectiveness of the studied centers, the network data coverage analysis was used, and toxic gases such as CO2 and SO2 were determined as the undesirable outputs of each stage. The results of the data analysis of 9 centers showed that none of the units had an efficiency of 1. Among them, the highest efficiency related to unit 1 was 0.8244; the lowest efficiency was related to unit 2 with an efficiency number of 0.6868; and unit 3 with an efficiency number of 0.6701. and unit 7 with an efficiency number of 0.6265. One of the most important reasons for the inefficiency of the mentioned units is related to sanctions for the purchase of machinery and equipment associated with the exploitation of crude oil and the production of pure oil and gas from materials extracted from underground.
