Patent number: 10760418Abstract: Methods and systems to preserve, prepare, extract, and/or analyze hydrocarbons in the pore spaces of or adsorbed in organic-rich rock samples, such as, but not limited to, drill cuttings and drill cores, using one or more combinations of physical energy sources, including, but not limited to, thermal, vapor pressure, and mechanical stress. The collected samples are transported and prepared in low temperature conditions, with parts of subsequent processing at very low temperatures, thereby allowing a fuller measurement of geochemical fingerprints for the extracted hydrocarbons using various analysis tools. More particularly, the treatment and process allows geochemical fingerprinting to very low carbon number ranges.Type: GrantFiled: April 23, 2019Date of Patent: September 1, 2020Inventors: Yifei Liu, Jiang Wu

Publication number: 20200252908Abstract: A resource allocation method for network slicing and an orchestrator, comprising: uniformly incorporating resources originally bundled statically with the base station into a dynamic resource pool; allocating, by an orchestrator, resources from among the dynamic resource pool for the network slicing based on different network slicing requirements. A static corresponding/mapping relationship between the hardware/radio resources and the base station is broken, such that hardware/radio resources (e.g., radio access network Virtual Network Function (RAN VNF), baseband unit (BBU), RRH (Remote Radio Head) as well as antenna) that originally corresponded to different base stations will be organized as an integrated and dynamic hardware/radio resource pool and reported to the orchestrator, such that the orchestrator will centrally manage all hardware/radio resources in this pool and then sufficiently utilize and dynamically orchestrate these hardware/radio resources based different needs from the network slicing.Type: ApplicationFiled: January 17, 2018Publication date: August 6, 2020Applicant: Alcatel LucentInventors: Yifei Liu, Haobo Xing, Xiaoxing Han, Jing Xia, Xiaogen Jiang, Min Zhang

Patent number: 10584276Abstract: A CO2-sensitive fracturing and displacement fluid contains a surfactant, an auxiliary agent, water, and CO2, wherein CO2 is liquid and/or supercritical CO2. The CO2-sensitive fracturing and displacement fluid provided by the invention does not flow back after completion of fracturing construction, and the gel breaking fluid displacement is carried out after soak for a period of time to improve the tight oil recovery ratio. The CO2-sensitive fracturing and displacement fluid exerts the “one-agent multi-purpose” function of sand carrying, CO2 energization and oil displacement, surfactant imbibition and oil discharge of a fracturing-displacement system in different development and production stages, and achieves the dual goals of expanding the utilization degree of tight oil and improving the displacement efficiency of the tight oil, which can effectively reduce costs and achieve the goal of unified, highly efficient and green development of oil and gas fields.Type: GrantFiled: April 23, 2019Date of Patent: March 10, 2020Assignees: CHINA UNIVERSITY OF PETROLEUM (EAST CHINA), CHINA UNIVERSITY OF GEOSCIENCES (BEIJING), SCIENCE AND TECHNOLOGY RESEARCH INSTITUTE LTD., PETRO CHINAInventors: Caili Dai, Mingwei Gao, Mingwei Zhao, Qing You, Guang Zhao, Yining Wu, Yongpeng Sun, Lin Li, Yifei Liu, He Liu, Xin Wang, Baoshan Guan
