Gas-to-liquids technology, as one of the methods for natural gas processing, while facilitating the transport of natural gas to remote locations, has attracted the attention of gas-resource-owning countries by creating added value and environmental advantages, as well as recovering associated gases and converting them into valuable products. In this article, while providing a brief introduction to the GTL process, the economic feasibility of constructing a hypothetical GTL unit under two patterns—'with' and 'without' expansion and exploitation of the gas reservoir—is evaluated. Based on the results obtained, the construction of GTL units is completely economically feasible; such that the added value of GTL products compared to natural gas is high, and their export is much more valuable in terms of national interests than selling natural gas through pipelines or LNG. Furthermore, considering the high cost of producing high-quality petroleum products from an environmental perspective in oil refineries, GTL products will be fully capable of competing in price with such products. Finally, by studying common investment methods in downstream gas industries, optimal strategies for providing financial resources and attracting technical knowledge for the project are introduced and examined.

If we consider the price of each cubic meter (rich gas) equal to 5/3 cents based on the average global natural gas price, the project's natural gas cost in each year (the year when the project has reached full capacity operation) is estimated to be around 202/7 million dollars.
gor Considering the average crude oil price in the past 7 years, which is calculated to be approximately 40 dollars based on the calculations in Table 8, and taking into account 3/5 dollars as the price difference between crude oil and GTL products and 2 dollars as the quality premium for GTL products, the price of products of this technology per barrel is estimated to be equivalent to 45/53 dollars.
D. Calculation of revenues: The revenue of the studied project, with a production capacity of 35,000 barrels per day and considering the selling prices of main and by-products under conditions of full operation of the plant's nominal capacity, is estimated at approximately 782/8 million dollars per year.
6. Independent Establishment of the GTL Product Manufacturing Unit In the project defined in the previous section, in order to separate condensates and natural gas liquids and to treat and refine them, a refinery is considered alongside the GTL plant.
Results of the economic evaluation of the project to establish a GTL product manufacturing unit along with gas reservoir development (Refer to the page image) Source: Based on the assumptions of previous tables Table 12.
Results of the economic evaluation of the project to establish a GTL product manufacturing unit independently (Refer to the page image) Source: Calculation results based on the assumptions of tables 1 to 11 7.
