Abstract:
A reservoir analysis method can include transmitting a signal from a downhole pump in a wellbore, receiving the signal at another wellbore, and determining a reservoir characteristic from the received signal. A reservoir analysis system can include a downhole pump positioned in a wellbore and a sensor positioned at another wellbore. The downhole pump selectively transmits a signal, and the sensor receives the signal. Another reservoir analysis method can include selectively changing a reciprocating displacement of a rod string connected to a downhole pump in a wellbore, transmitting a signal from the downhole pump in response to the changed reciprocating displacement, receiving the signal at another wellbore, and determining a reservoir characteristic from the received signal.
