Patent number: 11815352Abstract: A downhole borehole imaging tool and methods for determining a borehole size includes a magnetoresistive system and a hub moveably coupled to a fixed tool string. The hub includes a magnet. The magnetoresistive system includes magnetoresistive sensors disposed within the fixed tool string and segregated from the magnet. During operation, a routine scan of all sensors measures, for example, the output voltage V, angle ? of magnetic field, and temperature. Measurements from each sensor may then be characterized to account for temperature and input voltages variation of the sensors. The most accurate measurement can be used to derive the position of the hub 44 using the previous baseline parameters stored in the tool.Type: GrantFiled: March 30, 2021Date of Patent: November 14, 2023Assignee: Schlumberger Technology CorporationInventors: Julien Toniolo, Alan J.

Patent number: 9182747Abstract: The present disclosure relates to a method to determine the phase of a signal when transmitter and receiver circuits use separate clocks. A discrepancy between the separate clocks is determined, as is a correction factor between the separate clocks. The phase is determined using a measured time of arrival of the signal, the determined discrepancy, and the determined correction factor. A drift factor and an expected start time of a pulse sequence may be used to determine the discrepancy. A start time of a pulse within the pulse sequence is determined and used to determine the correction factor. The method works by either absolute synchronization of the separate clocks, or by making the measurements independent of clock synchronization.Type: GrantFiled: June 15, 2012Date of Patent: November 10, 2015Assignee: Schlumberger Technology CorporationInventors: Jean Seydoux, Libo Yang, Mark Kuchenbecker, Reza Taherian, Emmanuel Legendre, Jian Yang, Mark A.
