Publication number: 20210047918Abstract: An apparatus, method, and system for determining the propagation delay for a downhole wire and/or for monitoring the integrity of a downhole wire. The apparatus includes a first tool component and a second tool component spaced apart from the first tool component and communicatively coupled by a wire. The tool components include impedance altering devices configured to alter, for a predetermined period of time, either the source impedance at a first termination point of the wire and/or the load impedance at a second termination point of the wire sufficient to generate a characteristic signal reflection upon the transmission of a signal along a length of the wire between the first tool component and the second tool component.Type: ApplicationFiled: February 20, 2018Publication date: February 18, 2021Applicant: HALLIBURTON ENERGY SERVICES, INC.Inventors: Imran Sharif VEHRA, Christopher Allen GOLLA, Matthew Chase GRIFFING, Zinovy B.

Publication number: 20200080418Abstract: A bottom hole assembly includes a single wire bus, a legacy sensor coupled to the single wire bus, and at least one high frequency communication sensor coupled to the single wire bus. The high frequency communication sensor injects a high frequency signal alternating between high frequency synchronization pulses and high frequency data signals onto the single wire bus. A first high frequency pass filter coupled between the at least one high frequency communication sensor and the single wire bus is also included. The high frequency pass filter passes the high frequency signal to the single wire bus from the high frequency communication sensor. The bottom hole assembly includes a first high frequency blocking filter coupled between the legacy sensor and the single wire bus. The high frequency blocking filter blocks the high frequency signal from the high frequency communication sensor from disturbing a legacy signal at the legacy sensor.Type: ApplicationFiled: November 15, 2019Publication date: March 12, 2020Inventors: Imran Sharif VEHRA, Zinovy B.

Patent number: 6897651Abstract: The invention is a method of reducing the effects of non-formation signals in an NMR logging echo signal obtained within a borehole in an earth formation. The method obtains a non-formation signal by the application of at least an excitation pulse, and preferably also at least one refocusing pulse. The obtained signal is used to numerically construct a synthetic ringing signal sequence. The constructed signal can then be subtracted from an NMR echo signal to reduce the effects of ringing.Type: GrantFiled: May 15, 2003Date of Patent: May 24, 2005Assignee: Baker Hughes IncorporatedInventors: Arcady Reiderman, David R.
