The restrictions on oil reserves and environmental hazards have led resource-rich countries to focus their attention on gas energy. In this regard, the importance of gas as an appropriate energy source will become even more significant in the coming years. The establishment of a cartel consisting of natural gas producers and exporters in order to achieve strategies for managing and controlling the gas market demonstrates this importance. This paper examines the confrontation or interaction between oil OPEC and the Gas Exporting Countries Forum (gas GECF); using the time series data for OPEC and GECF gas and oil demand in the period from 1970-1 to 2016-4. Regarding the coefficients obtained from the estimation of OPEC and OPEC gas and solving their equations simultaneously in the MATLAB 2014 software, the following results have been obtained; based on the cumulative response function in the case of the formation of a gas cartel, these two cartels will choose collusion strategies. The reason for this can be searched in some common members of the two cartels. Also, based on the impulse response function, oil demand is evaluated more than gas demand. It can be due to the multiple uses of oil over gas which increase the intensive substitution between these two products..

The study has calculated the price path, extraction path and discounted profit for GECF and fringe group with use of genetic algorithm on the basis of Price leadership and collusion models. In this regard, members of "Gas Exporting Countries Forum" have been considered as a pricing cartel and other producers as the fringe group. For this purpose, annual data (1980-2010) is used for forecasting of studied trends up to year 2070.the result from price leadership model show that world gas demand Increases linearly over the time and it Increases exponentially. On this basis the supply of fringe group also grows increasingly, and the cartels supply (that is the margin between world demand and fringe supply) grows decreasingly. The results from collusion solution indicates that extraction trend is slower in compared with the price leadership solution and the price and profit in collusion solution is more than price leadership solution.
