Latest Patents
David Funkhouser holds a patent for a "Ground fault tolerant data communication system for a downhole instrument." This invention relates to a data communication system and method designed for use in downhole applications. It involves supplying electrical energy over a multiple-conductor power cable to a motor assembly of a downhole tool, such as an electric submersible pump. The system features a power leg coupling that interfaces a surface controller with the conductors of the tool's power cable. Uplink communication of telemetry data is achieved through current modulation generated by the downhole instrument and interpreted by a surface controller. Additionally, downlink communication of instrument data occurs over a different communication scheme supported by both the downhole and surface controllers. This downlink communication scheme not only provides power to the downhole instrument but also ensures the protection of downhole electronics and continuity of communication in the event of a ground fault on the power cable. The communication frequencies for both uplink and downlink are adaptive based on the frequencies and voltages present on the power cable.
