A quantitative oil and gas reservoir evaluation system for development

Abstract Accurately measuring and understanding reservoirs is critical for ensuring successful reservoir development, but there is a lack of quantitative and comprehensive evaluation systems available for assessing reservoirs for development purposes. This study developed a quantitative evaluation system to measure oil and gas reservoir readiness for development, considering the reservoir and input data quality. The reservoir quality index is determined using five major elements with the input data quality determined by the quality of six data sources. The weight of each element was determined using the principal component analysis method. The newly developed evaluation system was used to assess the development readiness of 20 reservoirs; the results of the reservoir application were analyzed in terms of the reservoir quality index and data quality index. Recommendations for dealing with reservoir developments with different evaluation results were also proposed. The evaluation system developed proved to be an effective method for evaluating reservoir development readiness based on the results of applications and feedback.
