Patent number: 9970273Abstract: A ground fault immune power and data delivery system for downhole sensors is connected to a downhole motor via a three-phase power cable. An AC power supply and sensor data module are connected to only two of the three phases to provide power and data signals to the sensors. During normal operation, power and data signals are transmitted over only one of the two connected phases. If a ground fault is detected on the third unconnected phase, power and data signals continue to transmit over the connected phase. If a ground fault is detected on one of the two connected phases, an isolation module isolates the grounded phase and switches to the ungrounded connected phase to continue transmitting power and data signals. If two of the phases are grounded, the motor shuts off; however, power and data signals may continue to transmit over an ungrounded connected phase.Type: GrantFiled: April 29, 2014Date of Patent: May 15, 2018Assignee: Halliburton Energy Services, Inc.Inventors: Sudhir Kumar Gupta, Patrick Phang

Patent number: 9935453Abstract: A ground fault immune power and data delivery system for downhole sensors is connected to a downhole motor via a three-phase power cable. An AC power supply and sensor data module are electrically connected to one of two conductors (phases) at a time selected from the three conductors (phases) to provide power and data signals to the downhole sensors. If a ground fault is detected on one of the two connected phases, an isolation module isolates the grounded phase and switches to the ungrounded connected phase to continue transmitting power and data signals. A frequency of AC power supply, data communication frequencies and a switching frequency of a drive controlling the downhole motor are orthogonal to each other in order to mitigate interference. Surface-to-downhole communication can occur by adjusting voltage, frequency and/or phase of AC power supply controlled by a processor.Type: GrantFiled: July 17, 2015Date of Patent: April 3, 2018Assignee: Halliburton Energy Services, Inc.Inventors: Yusef Alaas, Sudhir Kumar Gupta, Aram Shihab Khaleel Almuhana

Patent number: 9828850Abstract: An electrically powered artificial lift system includes a tubular for conveying a wellbore fluid upward and a downhole pump that urges the wellbore fluid into the tubular. A power cable conveys a three-phase power signal to the pump motor on three conductors. One of the three conductors is coupled to an internal node of a high-to-low voltage (HLV) source coupler via a low frequency blocking filter that shields the internal node from the motor power signal while conveying a sensor power signal from the internal node to the selected conductor and conveying a telemetry signal from the selected conductor and to the internal node. A similar downhole coupler couples a wye point of the motor to a downhole sensor assembly to supply the sensor power signal and to receive the telemetry signal.Type: GrantFiled: April 28, 2015Date of Patent: November 28, 2017Assignee: Halliburton Energy Services, Inc.Inventors: Srilatha Boyanapally, Aram Shihab Khaleel Almuhana, Sudhir Kumar Gupta

Patent number: 9738159Abstract: A system includes a grid coupled to an electrical bus; an electrical power modulation device coupled to the electrical bus that can output modified electrical power received from the electrical bus; a blower motor coupled to the electrical power modulation device that can receive the modified electrical power output and can provide a stream of air to affect a temperature of the grid, and a controller. A speed of the blower motor may be based at least in part on an amount of the modified electrical power. The controller can receive an operating parameter, and is responsive to that parameter by causing the electrical power modulation device to vary the amount of the modified electrical power. A blower motor speed may be controlled based at least in part on the operating parameter.Type: GrantFiled: May 17, 2016Date of Patent: August 22, 2017Assignee: General Electric CompanyInventors: Emil Nikolov, Ajith Kuttainnair Kumar, Theodore Clark Brown, Bret Dwayne Worden, Sudhir Kumar Gupta
