Publication number: 20220082009Abstract: A technique is provided to facilitate monitoring of contaminants which can potentially enter an electric submersible pumping system. A sensor system is used in conjunction with the electric submersible pumping system to detect the presence of specific contaminants which can affect future operation of the electric submersible pumping system. Depending on the embodiment, the sensor system may comprise a sensor or sensors disposed within the electric submersible pumping system and/or in or along components associated with the electric submersible pumping system. Each sensor is used to monitor for the contaminant and to provide data to a control system so as to facilitate decision-making regarding future operation of the electric submersible pumping system.Type: ApplicationFiled: December 19, 2019Publication date: March 17, 2022Inventors: Peter Hondred, Jason Holzmueller, Alejandro Camacho Cardenas, Johan Lindal Haug, Geir Kroslid, Jinglei Xiang, Gregory Howard Manke

Publication number: 20200194143Abstract: A technique facilitates construction and use of a power cable in a variety of environments, e.g. downhole environments. The power cable comprises a conductor, e.g. a plurality of conductors. Each conductor is surrounded by an insulation layer which is coated with a graphene-based ink. The graphene-based ink comprises graphene nanostructures and provides a flexible primary barrier coating for the power cable. The flexible primary barrier coating substantially increases fluid resistance of the insulation layer and also reduces transmission of downhole gases into the power cable insulation.Type: ApplicationFiled: December 12, 2019Publication date: June 18, 2020Inventor: Jinglei Xiang

Publication number: 20170162296Abstract: High reliability power cables for subsea application are provided. Example power cables provide enhanced resistance to partial discharge dielectric breakdown as well as resistance to explosive gas decompression, by eliminating micro-defects and voids at the interface between the insulation layer and the barrier layer during the cable manufacturing process. Lead metal, which is conventionally extruded as a primary barrier layer, is replaced in the example power cables by a gas-and-fluid-resistant thermoplastic that is co-extruded or tandem extruded with surface-modified insulation to promote bonding between the two layers. Elimination of lead metal in the example power cables also significantly reduces their overall weight. The improved resistance to partial discharge and resistance to rapid gas decompression translates to lower workover and lower cost of ownership.Type: ApplicationFiled: June 19, 2015Publication date: June 8, 2017Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Jinglei Xiang, Jason Holzmueller
