Latest Patents

One of Haijing Wang's latest patents is a system and method for determining water-filled porosity and water salinity in well cores and logs. This innovative method involves obtaining complex dielectric permittivity of earth formations, either from dielectric measurements representative of well cores or from dielectric well logs. The process includes selecting a dielectric mixing law for the index number m, plotting a m-th root of complex dielectric permittivity at a specified frequency in the complex domain, and determining matrix permittivity, water salinity, and water-filled porosity based on the complex dielectric permittivity and the dielectric mixing law. The results are then displayed for practical application.

Another notable patent focuses on NMR measured pore fluid phase behavior measurements. This method is designed to measure the phase behavior of a fluid in a porous medium, such as tight gas shale. The process involves loading the fluid into a sample cell, setting pressure and temperature, applying an RF pulse sequence to acquire an NMR signal, and deriving an NMR parameter distribution that depends on the pressure and temperature. This innovative approach allows for the determination of fluid phase presence and provides an estimated location of the phase boundary.
