Latest Patents

Yunke Liu holds a patent for a method of determining solid and liquid components in sedimentary rocks using NMR relaxation. This method separates liquid-like and solid-like NMR transverse relaxation times in porous media. It employs novel pulse sequences along with an NMR spectrometer optimized for geological core samples. The technique is applied to obtain one-dimensional T distributions and two-dimensional T-T maps in organic-rich chalks. This allows for the quantification of liquid-like signals, such as micropore fluids and clay-bound water, as well as solid-like signals, including kerogen and bitumen.
