Title: Liyong Li: Innovator in Subsurface Reservoir Characterization
Introduction
Liyong Li is a prominent inventor based in Livermore, CA (US). He has made significant contributions to the field of subsurface reservoir characterization, holding 2 patents that enhance the understanding and simulation of fluid flow in fractured reservoirs.
Latest Patents
Liyong Li's latest patents include a "System and method for characterizing fractures in a subsurface reservoir." This invention describes methods, systems, and software designed to optimize fracture characteristics and simulate fluid flow rates in a well model. The well model incorporates static and dynamic data, allowing for the simulation of fluid flow between fractures and the well. The properties of fractures, such as length, height, and aperture, are updated based on measured and simulated fluid flow rates. This iterative process continues until the simulated fluid flow rates align with the measured rates. Additionally, pressure data is utilized to determine gridblock permeability, enhancing the reliability of the fracture properties.
Another notable patent is the "Method, system and apparatus for simulating fluid flow in a fractured reservoir utilizing a combination of discrete fracture networks and homogenization of small fractures." This invention creates a three-dimensional hybrid reservoir model that accurately represents a fractured subterranean reservoir for fluid flow simulation. The model includes porous matrix blocks and a network of long fractures, which are fluidly connected to the matrix blocks. The effective fluid flow transmissibilities are determined, allowing for simultaneous solving of matrix and fracture flow equations. This approach provides a more realistic modeling of fracture characteristics compared to previous reservoir models.
