The development of dry gas field has an objection to maximize the financial profit, although it has to keep the plateau rate constant for certain plateau time. That is not an easy task to achieve because the production system contains many variables that have great impact for each other. The changing of one variable can affect another variable. The amount of gas flow from the reservoir to the bottom hole depends on piping system, and on the other hand, pressure changing on pipe also affected by gas flows. So, the integrated production system development for dry gas field is required to obtain maximum profit. Besides developing the integration to production system, the optimization for production variable also needed. The optimization model that will be used in this research is Genetic Algorithm, which has been used many times at oil and gas industry. The objective function defined for the model is maximizing Net Present Value (NPV) as an economic indicator by optimizing the tubing diameter, flowline diameter, and separator pressure. This research also will present the comparison of NPV value for different plateau rate. The NPV changing affected by plateau rate will be analyzed.
