    Abstract: An artificial lifting system is disclosed. The artificial lifting system comprises an elongated cylinder fixed to a base or ground. The elongated cylinder receives a piston rod axially movable therein. The piston rod engages a downhole rod pump for driving the rod pump reciprocating uphole and downhole to pump downhole fluid to the surface. A control unit controls the axial movement of the piston rod, and automatically adjust the system operation to adapt to drift of the top and bottom stop positions of the piston rod. In an alternative embodiment, the system further comprises a dump valve controlled by the control unit to prevent over-stroke. In another embodiment, the system further comprises a chemical injection unit for injecting treatment fluid to a wellbore under the control of the control unit.

    Abstract: A method and system for pumping unit with an elastic rod system is applied to maximize fluid production. The maximum stroke of the pump and the shortest cycle time are calculated based on all static and dynamic properties of downhole and surface components without a limitation to angular speed of the prime mover. Limitations of structural and fatigue strength are incorporated into the optimization calculation to ensure safe operation while maximizing pumped volume and minimizing energy consumption. Calculated optimal prime mover speed is applied to the sucker rod pump by means of beam pumping, long stroke or hydraulic pumping unit by controlling velocity, acceleration and torque of the electric prime mover or by controlling pressure and flow rate in hydraulically actuated sucker rod pumping system.

The pump control apparatus includes a first sensor for measuring strain on a structure of the well pumping system and a second sensor for measuring a position of the structure. The apparatus also has a controller configured to control the well unit by receiving output signals from the first and second sensors and generating control signals according to a motor control sequence. This controller may be mounted to the structure of the pumping system to measure the strain experienced by the structure. The control signals may be transmitted to a motor control panel using a cable-less communications system. Preferably, the first sensor, the second sensor, and the controller are integrated into a single unit. In another embodiment, the pump control apparatus may be self-powered.

    Abstract: A method is provided to monitor operation of a sucker rod pump, the sucker rod pump having a strain gauge mounted on a walking beam for determination of load. This method compensates for gradual changes in load due to temperature drift when gradual changes in surface card area are occurring and the surface card area or the measured average loads are within a range of a predetermined base surface card area or base average load. When the surface card area or the measured average load is not within this predetermined range, a correction is made to adjust a smoothed minimum load to an adjusted buoyant weight of the sucker rod string. This adjusted buoyant weight is the value that the smoothed minimum load would be expected to be. This algorithm therefore compensates differently for changes in load when the surface card area (or alternatively, the average load) are not within a predetermined value because these changes are generally not due to temperature changes, but due to changes in the operation for which the sucker rod pump monitoring and control system should respond. An alternative correction to the measured load is also provided for time periods when the sucker rod pump is idle.
