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.
