Comprehensively evaluating the petroleum exploration success based on PCA and synthetic index method
摘要
Abstract
Petroleum exploration success is commonly evaluated using each of indexes,for example reserve-discovered cost and proven geological reserves per well.Such evaluation pattern,however,is too simple,bringing about the evaluated index incapable of mirroring the internal composition in this success thoroughly and systematically,and the evaluated results failing to give objective response to practical benefits.It is hard to make measures in depth.Thus,dependent on some achievement data of recent years,the exploration success was quantitatively appraised through the created comprehensive evaluation model.Results show that(i)with the success as the soul,the preliminary index system covering four categories and nineteen sub-indexes is set up through sorting out principal indexes which may characterize the success at the whole exploration process;(ii)including four categories and thirteen sub-indexes,the core index system is also built by means of the principal component analysis(PCA)to screen indexes;(iii)the scoring coefficient is attained for each index by way of PCA.And taken the coefficient share as the weight,the comprehensive evaluation model is developed through the synthetical index method;and(iv)in accordance with the appraised success,the standard for success division is established by means of k-means cluster analysis.In conclusion,these established systems are rather reasonable and the evaluated results boast the quality of objectivity,which is conducive to the petroleum exploration success in continuous optimization.关键词
