Latest Patents

One of Liu's latest patents is titled "Method for producing heavy oil by generating solvents in situ in the reservoir." This invention involves using an electric heating device to heat crude oil in the reservoir near the wellbore to a target temperature. Chemical reaction additives are injected to facilitate high-temperature thermal cracking and aquathermolysis of crude oil, generating light hydrocarbon components and gases. These components rise to the steam chamber, where they dissolve in the crude oil, reducing its viscosity and increasing the production rate.

Another significant patent is the "Integrated method for nitrogen-assisted carbon dioxide fracturing and development of shale oil reservoirs." This method outlines a process for fracturing shale reservoirs using nitrogen-assisted carbon dioxide. It includes steps for injecting carbon dioxide gas followed by nitrogen gas to enhance oil recovery. This integrated approach maximizes recovery efficiency and streamlines field operations, making the development of shale reservoirs more economical and efficient.
