Patent number: 11953639Abstract: Some aspects relate to techniques for calibrating a logging tool. In some implementations, the logging tool may estimate certain unknown properties of a signal based on distances between transmitters and receivers of the logging tool and based on frequencies used by the transmitters and receivers. The logging tool may estimate the unknown properties by interpolating values into a mathematical function related to the above-noted distances and frequencies. After estimating the unknown properties, the logging tool may be deployed into the wellbore, where it may use the estimated properties to process signals received through a subsurface formation.Type: GrantFiled: March 17, 2022Date of Patent: April 9, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Yijing Fan, Hsu-Hsiang Wu, Jin Ma, Li Pan

Publication number: 20240102374Abstract: Aspects of the subject technology relate to systems, methods, and computer-readable media for identifying a borehole correction factor for determining a true resistivity by selecting a model to apply in identifying the borehole correction factor and applying the model to an apparent resistivity to identify the borehole correction factor. To perform borehole correction, a multiplicative coefficient is needed to apply to the apparent resistivity. A database of this multiplicative coefficient, called the borehole correction factor, is generated based on the borehole correction model. The technology described herein allows operators to avoid time-consuming variable borehole diameter sweeps and complex borehole diameter inversion current used in resistivity logging software.Type: ApplicationFiled: September 26, 2022Publication date: March 28, 2024Applicant: Halliburton Energy Services, Inc.Inventors: Xiang WU, Yi Jing Fan, Jing Jin

Publication number: 20200149185Abstract: The present application provides a reflective screen of a monocrystal growth furnace and the monocrystal growth furnace. The reflective screen comprises an inner cylinder, an outer cylinder, a thermal insulating material sandwiched between the inner and the outer cylinders, and a thermal insulating pad disposed at the joint of the inner and the outer cylinders. The reflective screen and the monocrystal growth furnace are able to decrease the thermal transmittance from the outer cylinder to the inner cylinder, increase the vertical temperature gradient of the ingot, and prevent or decrease the silicon oxides evaporated from the molten silicon to condensate on the outer cylinder of the reflective screen. Thereby, polycrystalline caused by the oxides falling into the molten silicon can be reduced. Moreover, the thermal power required during the growth of monocrystalline silicon can be reduced because of the reduction of unnecessary thermal transmittance.Type: ApplicationFiled: November 6, 2019Publication date: May 14, 2020Inventors: WEIMIN SHEN, JIN FAN, GANG WANG, WEE TECK TAN
