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: An oil well pumping system having stroke optimization is provided. The system includes a downhole pump residing within a wellbore, and a rod string extending down into the wellbore and connected to the pump. The system also includes a well head having an actuator configured to reciprocate the rod string and connected downhole pump as upstrokes and as downstrokes, and a pump stroke controller. The pump stroke controller is configured to adjust a speed of the upstroke and a speed of the downstroke in response to signals indicative of pump fillage. In one aspect, the pump stroke controller tunes the pumping speed to match an average in-flow of production fluids into the pump over a multiple hour period to provide an optimum speed. A method for optimizing pumping speed at a wellbore is also provided herein.

Abstract: A sludge flow monitoring system and method measures volume of sludge pumped by a positive displacement pump through a pipeline by determining a fill percentage during each pumping cycle. The start and end of each piston stroke are identified by hydraulic system sensors. The fill percentage is determined based upon a first summation of periodic piston speed command values from the start of a pumping stroke to the end of a pumping stroke, and a second summation of periodic piston speed command values from a poppet valve opening indicating output flow from the pump to the end of the pumping stroke.

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.

Abstract: One or more techniques and/or systems are disclosed for increasing compressed air efficiency in a pump that utilizes an air efficiency device in order to optimize the amount of a compressed air in the pump. The air efficiency device may allow for controlling the operation of the air operated diaphragm pump by reducing the flow of compressed air supplied to the pump as the pump moves between first and second diaphragm positions. A sensor may be used to monitor velocity of the diaphragm assemblies. In turn, full position feedback is possible so that the pump self-adjusts to determine the optimum, or close to optimum, turndown point of the diaphragm assemblies. As such, air savings are achieved by minimizing the amount of required compressed air.

Abstract: A linear compressor driving apparatus (101) according to the present invention is a linear compressor driving apparatus having an inverter (2) which supplies a driving current of a predetermined frequency to a linear compressor (100), and the apparatus further includes an inverter controller (6) for controlling the inverter (2) on the basis of resonance frequency information so that the frequency of an output current from the inverter becomes equal to the resonance frequency, and instantaneous values of an output current Id and an output voltage Vd from the inverter (2) are measured at a phase timing in which an amount of change in the output current Id of the inverter (2) becomes zero, and a piston stroke is calculated from these measured values. In such linear compressor driving apparatus (101), a stroke and a top clearance of the piston of the linear compressor can be accurately detected by relatively simple arithmetic processing, without using a position sensor.
