Abstract: A system for monitoring performance of a pumping unit of an oil well includes a first sensor for measuring the inclination angle of a beam forming part of the pumping unit, a second sensor for measuring the load on the beam, and a third sensor for measuring the load on an electrical motor used in conjunction with the pumping unit. The first sensor includes a cantilevered pendulum member which moves in response to changes in the beam inclination angle and strain gauges affixed to the pendulum member for generating an electrical signal indicative of the instantaneous inclination angle. The second sensor includes a deformable sensor plate mounted to the beam and piezoresistive gauges attached to the plate for providing a signal indicative of the load on the beam. The third sensor includes a sensor head attached to a cable for supplying electrical power to the motor. The sensor head includes a sensor coil spaced from the cable so that the magnetic field surrounding the cable induces a current flow in the sensor coil. By measuring the voltage across the ends of the sensor coil, a signal indicative of the load on the motor is generated.

Abstract: A control circuit for turning off the electrical power to the drive motor, which reciprocates a polished rod of a pump, when the pump has exhausted the supply of liquid in the well. Simultaneously measuring the polished rod load and rod position and turning off the power when the load is greater than or equal to a preset load and the position is equal to a preset position on the downstroke of the well. A first comparator measures the polished rod load relative to a preset load, and a second comparator measures the polished rod position relative to a preset point so that the power is shut off when the load is greater than or equal to the preset load and the position is equal to the preset point on the downstroke. A set of digital latches act to insure that the load is greater than the preset load for two consecutive strokes before the power is shut off. Measuring when the polished rod load is less than a preset load and the polished rod position is equal to a preset point on the upstroke and turning off power to the well and signalling that an abnormal condition exists at the well. Connections are provided for an external plotter so that a plot of load versus position can be plotted to give a visual representation of the well activity.

Abstract: Methods and systems are provided to adaptively control a hydraulic fluid supply to supply a driving fluid for applying a driving force on a piston in a gas compressor, the driving force being cyclically reversed between a first direction and a second direction to cause the piston to reciprocate in strokes. During a first stroke of the piston, a speed of the piston, a temperature of the driving fluid, and a load pressure applied to the piston is monitored. Reversal of the driving force after the first stroke is controlled based on the speed, load pressure, and temperature.

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.
