Study On Technical And Economic Evaluation Method Of Natural Gas Resources

In this paper, the author points out that in order to ensure profitable and sustainable development of discovered gas fields for the sake of the development of the gas industry in a trend that the global energy consumption direction is changing and in the context that gas has an elevated position in the energy structure, we are required to study economic analysis methods of gas resource that theoretically analyze influential factors and determine major indicators so as to conquer the economic and effective development challenge of resources. For the gas industry, many researches on economic analysis methods and indicator systems of energy have been carried out in China. However, gas was usually considered as byproduct of crude oil for analysis and estimation due to its small production in the past. From the perspective of economic evaluation method, each method has its own applicable conditions and there is no technical and economic evaluation method especially designed for gas resource. Along with the development of the gas industry in China, it’s necessary to analyze economic laws. In this paper, the author compares the commonly used technical and economic evaluation methods of gas development as well as the economic evaluation methods used for different developing stages of gas fields in and outside China, carries out an economic analysis of gas productivity construction projects, and applies the economic evaluation methods to the upstream resources in reality to find distinct applicable scope of each method. By combining different methods with overall optimization and control, the author minimizes fund risks and acquires high return on investment, realizing the purpose of increased and stable gas production through economic evaluation.
