Latest Patents

One of Jianfen Du's latest patents is a method of preparing degassed oil representative of live oil with equivalent minimum miscible pressure. This innovative approach utilizes a Hydrophilic-Lipophilic Deviation theory-based method to prepare representative degassed oil. The method reduces the number of trial and error experiments during the preparation process by measuring the minimum miscible pressure (MMP) and equivalent alkane carbon number (EACN) for both dead and live oil. The formulation of the representative degassed oil can be easily predicted after determining the required MMP and EACN values. This prepared oil accurately reflects the key mechanisms of multiple contact miscibility during gas flooding, allowing for experiments that are inconvenient to conduct with live oil.

Another significant patent by Du is a method for evaluating the difference in gas injection effect of gas injection wells in carbonate reservoirs. This invention addresses the challenge of systematically evaluating the varying effects of gas injection wells, which has been a limitation in prior art. By employing this method, the reasons for low gas injection efficiency corresponding to different geological classifications can be identified. The systematic classification and induction of the differences in gas injection effects provide a solid foundation for designing effective gas injection schemes, ultimately guiding the later stages of gas injection and production increase in carbonate reservoirs.
