Economic Evaluation Methods Research On Investing In The Development Of Gas Fields

With the world's oil and natural gas energy prices rising steadily, reducing investment and development costs has become a top priority, and the level of its economic evaluation of the accuracy has put forward higher requirements. Throughout the academic literature at home and abroad, the exploration and development of oil and gas resources in the part of the evaluation are involved mainly, while some issues, there are still a number of differences, methods and systems are getting more mature, however, almost no natural gas exploration and development evaluation of specific methods are listed separately. In this paper, the purpose of the study is to do more in-depth study on the economic evaluation of oil and gas according to resources the situation of China's existing resources, do analysis to different types of gas field development phase of the different characteristics, evaluation of investment-benefit, for the purpose to find out more applicable gas investment evaluation methods.This paper cited the used methods of the development of oil and gas resources in the economic evaluation firstly, and then do a comprehensive analysis to the basis of lots of documents and scientific research, compared the similarities and differences of evaluation methods in oil field investment and gas field investment, then enter the main part of the article focused on the economic evaluation of investment in gas method. The specific methods are cited in the part, then on the basis of the data of the specific gas project development and investment, implicating and improving the methods involved, made a number of improved economic evaluation of the accuracy of views to explore,finally concluded.In this paper, the objection of study is based on the economic Evaluation Methods Research of Investing in the development of gas fields, according to the traditional methods of economic evaluation, using the theory of technical and economic evaluation and typical mathematical model, on the basis of the data of the development of gas fields, the evaluation methods To invest in the development of project are more specific in-depth study. Come to the conclusion in the following areas: the similarities and differences of evaluation methods between traditional oil field investment and gas field investment; the target of the evaluation must be defined first in the process of economic evaluation for investing in the development of gas fields; For each type of gas separation various stages of development and thereby identify different stages of the production effects of the basis of indicators; for the absolute quantity of benefit assessment of a certain year in a gas field project, taken by the internal and external efficiency-benefit analysis of the evaluation methods; on the gas field projects in different years between the various indicators of vertical comparison, this paper is based on Grey Correlation Analysis.
