Patent number: 11970931Abstract: A method and system for identifying bonding between a material and tubing. The method may include disposing an acoustic logging tool in a wellbore, wherein the acoustic logging tool comprises a transmitter, a receiver, or a transceiver, broadcasting a shaped signal with the transmitter such that the shaped signal interacts with a boundary of a casing and a material and recording a result signal from the boundary with the receiver. The method may further comprise identifying a cut-off time to be applied to the result signal, transforming the result signal from a time domain to a frequency domain, selecting one or more modes sensitive to a bonding at the boundary between the casing and the material, computing a decay rate of the one or more modes that were selected based at least one or more decay curves, and converting the decay rate to a bonding log.Type: GrantFiled: June 1, 2021Date of Patent: April 30, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Yao Ge, Ho Yin Ma, Ruijia Wang, Jing Jin, Brenno Caetano Troca Cabella, Xiang Wu

Patent number: 4794217Abstract: A semiconductor wafer is transported by a mechanical system into or out of a quartz housing filled with a protection gas. The wafer is placed between and spaced apart from two graphite plates. A RF induction coil surrounding the quartz housing is used to heat the graphite plates. Radiation from the heated graphite plates heats the wafer from room temperature to an elevated desired temperature. During the time period when a wafer absorbs radiation primarily through electron-to-electron transition, heat convection and conduction by the protection gas conveys heat from the graphite plates to the wafer to accelerate the heating of the wafer and reduces temperature nonuniformity of the wafer.Type: GrantFiled: April 15, 1987Date of Patent: December 27, 1988Assignee: Qing Hua UniversityInventors: Pei Xin Quan, Dong Yan Hou, Bi-Xian Chen, Teng Ge Ma, Hui Wang Lin, Zhi Jian Li
