Study On The Influence Factors And Evaluation Index Set Of Oil And Gas Reserve Assets Value

Oil and gas assets value assessment is the basis of oil and gas projects for major investment decisions and foundation.Accurate assets value system assessment is becoming more and more important.Building oil and gas assets value evaluation system and method is the key to asset valuation.Based on the detailed investigation of oil and gas assets value evaluation methods both at home and abroad,this paper comprehensively analyze the oil and gas reserves and asset value connotation.By using reservoir engineering theory,seepage theory and probability and statistics methods,researches on oil and gas assets value factors and evaluation system are conducted as follows.Firstly,oil and gas assets value evaluation index and construction specifications are established from both aspects of development risk assessment and production benefits evaluation in order to the build the follow-up evaluation system.Secondly,in the light of the theory of cost differential and principal component analysis method,5 main types of cost differential have been determined and the assessment models of oil and gas reserves value has been established.Consequently,reserves development risk evaluation of oil and gas can be obtained.Thirdly,a suitable net present value method to evaluate development benefit is established and the affecting factors of oil and gas development and production earnings are analyzed systemetrically.Lastly,based on the characteristics of oil and gas development and production benefits evaluation,Monte-Carlo method is introduced to analyze probability distribution characteristics of various factors of oil and gas production.As a result,the confidence interval of oil and gas production yield is also obtained.Finally,the research result can provide the technical support for oil and gas field exploration and development decision-making.This paper has established the evaluation system reflecting the oil reserves value and development benefit.Different types of oil field development risk and production benefits evaluation index and evaluation procedures are derived.The economic uncertainty of actual oil field development plan is also analyzed.Consequently,research results will provide the technical support of oil and gas field exploration and development decision-making.
