Patent number: 11957764Abstract: The disclosure relates to a protein-type nanoparticle for multi-specific antibody delivery, a preparation method, and its application. The protein-type nanoparticle includes a polyester and a protein with a hydrophobic domain, and the hydrophobic domain of the protein is bound with the polyester through hydrophobic interactions. The protein is at least one of albumin, globulin and cell wall protein. The protein-type nanoparticle of the present disclosure has excellent stability and biocompatibility. The protein-type nanoparticle is used to prepare a multi-specific antibody delivery platform (?Fc-NP) by binding anti-IgG-Fc antibody or anti-IgG-Fc antibody fragment, which can stably, quickly and easily bind to multiple specific antibodies through antigen-antibody interaction and enhance the therapeutic effect of specific antibodies.Type: GrantFiled: January 27, 2023Date of Patent: April 16, 2024Assignee: SOUTH CHINA UNIVERSITY OF TECHNOLOGYInventors: Jun Wang, Zhiting Cao, Song Shen, Qianni Ye, Xiaojiao Du, Xianzhu Yang, Youyong Yuan

Publication number: 20230323772Abstract: Embodiments for generating a reservoir performance forecast are provided. The embodiments may be executed by a computer system. In one embodiment, a method includes obtaining inflow performance relationship data generated from a physics-based subsurface-surface coupled simulation model having a surface, a subsurface, and one or more wells fluidly connecting the subsurface to the surface. The inflow performance relationship data comprises performance data for at least one phase of fluid for each well. The method also includes generating a performance forecast for the reservoir using a subsurface simulator and a surface simulator. The subsurface simulator uses the inflow performance relationship data to represent the subsurface during generation of the performance forecast, and the performance forecast satisfies constraints solved by the surface simulator. In one embodiment, a method does not utilize a surface simulator.Type: ApplicationFiled: April 12, 2022Publication date: October 12, 2023Applicant: CHEVRON U.S.A.

Publication number: 20230169237Abstract: Embodiments of conservative, sequential fully implicit compositional reservoir simulation are disclosed where 1) pressure, 2) saturation, 3) component balance, and 4) phase equilibrium are computed sequentially to solve for movement of liquid and gas phases over a series of time-steps until convergence to represent fluid flow within the subterranean reservoir. All molecular components in each of the liquid and gas phases are fixed to move with an equivalent phase velocity. Thermodynamic fluxes are accounted for when computing phase equilibrium by computing a difference between fluid volume and pore volume. A hybrid upwinding scheme can be employed to reorder cells based on upwind direction to improve the saturation convergence, especially when phase equilibrium significantly alters the cell properties.Type: ApplicationFiled: April 16, 2021Publication date: June 1, 2023Inventors: Seong Hee Lee, Matei Tene, Song Du, Xian-Huan Wen, Yalchin Efendiev
