Abstarct: The use of clean energy is one of the main topics of discussion in countries around the world, but what has doubled the attention to such energy, especially in recent years, is the rapid growth of air pollution and global warming. Energy experts recommend using more natural gas. Therefore, natural gas is one of the most important energy sources that plays a very important role in meeting energy demand; In addition to the rapid growth of air pollution and global warming, factors such as better resource dispersion, cheaper prices, and lower extraction costs have added to its importance. Gas resources are found in abundance in Iran and is the second largest in the world with its abundant gas reserves. Since Iran is the second largest holder of gas resources in the world, but it is facing a shortage for allocation to the domestic sector and exports. In this research, using the system dynamics approach, we will simulate and study the influential factors such as drilling operations, exploitation rate and seismic capability and reservoir modeling on gas production and its allocation to domestic and export sectors, and due to the increase in average growth. Gas consumption in the next 10 years, we can respond to the increase in consumption by using the above factors.
