"Enhanced oil recovery (EOR) processes are regarded as important methods to recovery remaining oil after primary and secondary recovery. It is significant to select the most appropriate EOR process among the possible techniques for a candidate reservoir. EOR screening criteria has been created using available EOR datasets and served as the first step to compare the suitability of each EOR method for a particular reservoir. Most of these datasets are collected from EOR surveys published by Oil & Gas Journal. This study proposes a comprehensive study of a dataset including 55 pilot and field polymer flooding applications in China. Statistical …

"Field experience has shown that CO2 miscible flooding is an effective method to improve oil recovery, but only with proper reservoir candidate selection and optimal project design. This paper discusses both CO2 miscible and immiscible flooding mechanisms and offers some guidelines for flooding operations. New developments in MMP determination are also introduced.
This research is based on a summary of field data from 134 CO2 projects in the U.S. Several numerical methods have been applied for data cleaning. After cleaning, data from 128 projects have been analyzed and correlated. Carbonate reservoirs and sandstone reservoirs are the two …
