Application of Grey Theory for Oil and Gas Reservoir Evaluation Program Optimization

Oil and gas reservoir evaluation is to evaluate the reserves in large scale or with special significance, and select the block for development. Oil and gas reservoir evaluation program includes a series of technical and economic indicators. Therefore the program optimization of oil and gas reservoir evaluation project is a system with multi-attribute. In order to optimize program comprehensively and systematically, it must establish a multi-level system of technical and economic indicators. Combining with the degree of gray incidence, the paper establishes a multi-level gray comprehensive evaluation model for oil and gas reservoir evaluation project, and applies the model to the practical example. The results show that the model is effective especially for the circumstance of the small sample or the limited amount of data. In addition, the model offers decision makers a new method to select favorable program.
