    摘要： Systems and methods for reliably communicating data at high data rates between surface and downhole equipment over a power cable by multiplexing data, modulating the data onto orthogonal carrier frequencies, communicating the modulated carrier signals over the power cable, recovering of the modulated signals, and demodulating the data stream from the recovered signal. One embodiment comprises a system that includes surface equipment connected by a power cable to an ESP system that has a gauge package connected to it. The gauge package uses a high-temperature DSP to perform the data processing associated with OFDM communications.

    摘要： Embodiments of the present invention beneficially provide circuits and methods which isolate downhole electronics of a well pump assembly from a power surge. The pump assembly includes a motor and a housing, including head, base, and manifold plate. The head has a hollow interior and a shoulder. The head is mounted to the motor so that, in operation, oil from the motor fills the interior of the head. The base has an outside diameter to fit snugly inside the head. The manifold plate is located between an upper end of the base and the shoulder of the head so that the axis of the manifold plate is perpendicular to the axis of housing. A gauge circuit and an isolation circuit are mounted to the manifold plate. The isolation circuit includes active semiconductor elements to detect excessive voltage and to protect the gauge circuit from the excessive voltage.

    摘要： Seismic data is collected by using an electrical submersible pump assembly in a well that is producing well fluid. By sweeping the rotational speed of the pump assembly through a selected range at selected intervals, seismic waves of varying frequency are emitted. These seismic waves are then picked up with a seismic sensor located at the surface or located in another well. If the seismic sensors are located in another well, the signal from the sensor may be transmitted to the surface by superimposing the data onto the power cable leading to the pump located in that other well. The seismic survey may be repeated at regular intervals, and the results will reveal the changes that have taken place over time in the reservoir.
