摘要： A hydraulic pumping system can include a hydraulic actuator with a magnet that displaces with a piston, and a sensor that continuously detects a position of the magnet. A ferromagnetic wall of the hydraulic actuator is positioned between the magnet and the sensor. A hydraulic pumping method can include incrementally lowering a lower stroke extent of a rod string reciprocation over multiple reciprocation cycles of the rod string, and automatically varying the lower stroke extent or an upper stroke extent of the rod string reciprocation, in response to a measured vibration. Another hydraulic pumping method can include solving a wave equation in the rod string, and automatically varying a reciprocation speed of the rod string in response to a change in work performed during reciprocation cycles of the hydraulic actuator or a change in detected force versus displacement in different reciprocation cycles of the hydraulic actuator.

摘要： A well pumping system can include an actuator that reciprocates a rod string, and a rod rotator including at least one helical profile and at least one engagement device. The rod string may rotate in response to longitudinal displacement of the rod string while the engagement device is engaged with the helical profile. A method of rotating a rod string in a well can include rotating a rod in a rotary direction, in response to displacement of the rod in a longitudinal direction, and preventing rotation of the rod in an opposite rotary direction, in response to displacement of the rod in an opposite longitudinal direction.

摘要： A well pumping system can include an actuator that reciprocably displaces a rod string, a flowmeter that measures flow of a fluid between a power source and the actuator, and a control system that modifies reciprocal displacement of the rod string by the actuator, in response to an output of the flowmeter. A well pumping method can include reciprocably displacing a rod string, continuously determining a velocity profile of the rod string, and modifying the velocity profile while the rod string reciprocably displaces, in response to an output of a flowmeter. Another well pumping method can include reciprocably displacing a rod string with an actuator, continuously determining displacement in response to an output of a flowmeter, and modifying reciprocating displacement of the rod string by the actuator, in response to the output of the flowmeter.

摘要： 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.
