Patent number: 11613985Abstract: A technique facilitates smart alarming, event detection, and/or event mitigation. The smart alarming may be achieved by, for example, automating detection processes and using advanced signal processing techniques. In some applications, event detection is enhanced by combining different alarms to facilitate diagnosis of a condition, e.g. a pump condition. The occurrence of certain unwanted events can be mitigated by automatically adjusting operation of a well system according to suitable protocols for a given event.Type: GrantFiled: November 13, 2014Date of Patent: March 28, 2023Assignee: Sensia LLCInventors: Dudi Abdullah Rendusara, Luis Parra, Roderick Ian MacKay, Ming-Kei Keith Lo, Jeffery Anderson

Patent number: 11408270Abstract: A technique facilitates testing and monitoring of a well. An artificial lift system is operated to produce a well fluid, and data is collected as the artificial lift system is operated at different flow rates. The data collected at the different, e.g. varying, flow rates is used in estimating flow performance and to enable continued monitoring of the well. In some applications, the data may be obtained by utilizing a virtual flow metering technique.Type: GrantFiled: November 13, 2014Date of Patent: August 9, 2022Assignee: Sensia LLCInventors: Yves-Marie Clet Robert Subervie, Dudi Abdullah Rendusara, Roderick Ian MacKay

Patent number: 10938390Abstract: A system can include a housing that defines an interior space; a shaft disposed at least in part in the interior space of the housing where the shaft includes a longitudinal axis, a curved surface and an end surface; a submersible electric motor operatively coupled to the shaft where the submersible electric motor includes a cable connector; two proximity sensors where each of the proximity sensors includes a sensor aperture disposed in the interior space of the housing; and circuitry operatively coupled to the proximity sensors that determines position values of the shaft with respect to time based at least in part on output of the proximity sensors.Type: GrantFiled: June 30, 2016Date of Patent: March 2, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Alejandro Camacho Cardenas, Peter Benjamin Johnson, Leo Steenson, Dudi Abdullah Rendusara, Andrew William Meredith

Patent number: 10900489Abstract: A technique facilitates automatic commissioning operations on pumping systems, e.g. electric submersible pumping systems. The automatic commissioning technique employs closed-loop monitoring and control processes which may include monitoring of pump shaft direction and speed measurements. In many applications, the technique reduces the time and manual effort otherwise involved in commissioning pumping systems in well completions. Embodiments also may be employed in automated decision-making related to commissioning and in determining operational settings based on sensed environmental and/or well performance conditions.Type: GrantFiled: November 13, 2014Date of Patent: January 26, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Dudi Abdullah Rendusara, Roderick Ian MacKay

Patent number: 9714568Abstract: Event-based telemetry for artificial lift in wells is described. An example downhole system can sense triggering events and anomalies in a well or electrical submersible pump (ESP) string, and send information about the triggering event with priority to a monitoring and control system. A telemetry manager can select specific sensors to address the triggering event, and then determine how frequently the selected sensors acquire or sample sensor data. The telemetry manager may then assemble a data stream that prioritizes the sensor data for transmission on limited bandwidth, thereby sending the most important data about the triggering event with the highest priority, even when there is limited transmission bandwidth available.Type: GrantFiled: November 11, 2014Date of Patent: July 25, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Dudi Abdullah Rendusara, Luis Parra, Adrian Ronald Francis
