Tight gas is one of the non-conventional hydrocarbons that are now begin to be developed in several countries. In general, tight gas reservoir has a large amount of reserves that can be produced in a long period of time, but this reservoir has a relatively low permeability of less than 0.1 mD and low production capacity. In an effort to increase the rate of gas production from this reservoir, there are several techniques, some of them are using horizontal wells. In the optimization studies of tight gas production, will be studied model of heterogeneous two-phase fluid reservoir that takes from Gulfaks Field reservoir model framework by providing the permeability rates of 0.01 - 0.0675 mD and Initial Gas In Place of 142 BSCF. This reservoir is produced using horizontal wells without hydraulic fracturing with a certain plateau rate. The model is optimized with several gas production field development scenarios and conducted sensitivity for length of lateral horizontal wells, contract time, and economic. In the economic analysis, carried out the sensitivity of the MARR, the price of gas purchased by PLN, the price of electricity purchased by PLN, and the selling price of electricity to the public. In the end, the resulting scenarios will provide the optimum gas production and provide a high enough profit for the contractors and PLN as well as meet the electricity needs of the community for a long time.
