Latest Patents

Wenhua Zhao's latest patents include a method for preparing degassed oil representative of live oil with equivalent minimum miscible pressure. This innovative approach utilizes a Hydrophilic-Lipophilic Deviation theory to streamline the preparation process. By measuring the minimum miscible pressure (MMP) and equivalent alkane carbon number (EACN) for both dead and live oil, the method reduces the need for extensive trial and error experiments. The resulting degassed oil formulation can be accurately predicted, allowing for more efficient experimentation in gas flooding scenarios.

Another significant patent is a method for determining the phase-state type and saturation of fluid in tight reservoirs using NMR technology. This method involves placing a core sample in an NMR phase-state testing device and injecting a heavy water solution to reach formation pressure. The process includes scanning the core to create a two-dimensional NMR map, which helps identify the presence of gas phases. By collecting various phase volumes and performing dry distillation, the method provides accurate saturation measurements of the fluid phases within the core.
