Patent number: 10830038Abstract: Communication methods and systems for communicating from a surface location to a downhole component in a borehole in an earth formation are described. The methods and systems include modulating, by a first device at the surface location, a fluid flow through a mud motor according to a predetermined pattern, the mud motor disposed in the borehole, the modulated fluid flow generating a mechanical movement variation pattern of at least a part of the mud motor, detecting, by a second device in the downhole component, the mechanical movement variation pattern, and demodulating the mechanical movement variation pattern to receive a signal that is related to the predetermined pattern.Type: GrantFiled: May 21, 2019Date of Patent: November 10, 2020Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Andreas Hohl, Wojciech Emmerich

Publication number: 20160245078Abstract: A method for transmitting data from a downhole location to a location at the surface of the earth includes: receiving data using a modulator disposed at the downhole location on a drill tubular in a borehole penetrating the earth and modulating the data using offset quadrature phase shift keying (OQPSK) and smooth transitions between phase shifts to produce a series of two-bit symbols having smooth transitions in transition intervals between phase shifts of both in-phase and quadrature-phase components of the OQPSK modulated data. The method further includes transmitting the series of two-bit symbols as an acoustic signal in drilling fluid disposed in the borehole using a mud-pulser, receiving the acoustic signal using a receiver disposed uphole from the downhole location; and demodulating the acoustic signal using a demodulator coupled to the receiver to provide demodulated data.Type: ApplicationFiled: February 19, 2015Publication date: August 25, 2016Applicant: BAKER HUGHES INCORPORATEDInventors: Sameh Amr Hassanein Mahmoud, Jens Uwe Bruns, Wojciech Emmerich, Matthias Gatzen
