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 pump apparatus has a downhole pump disposed in a wellbore and has a motor at the surface, and a rod string operatively moved by the motor reciprocates the downhole pump in the wellbore. Downhole data indicative of load and position of the downhole pump is generated using surface measurements and a wave equation model having an upstroke damping factor and a downstroke damping factor. Actual fluid load lines are determined from the downhole data for upstrokes and downstrokes of the downhole pump, and calculated fluid load lines for from the strokes are determined from the distribution of the load values in the downhole data. The actual fluid load lines are compared to the calculated fluid load lines to determine if the downhole card is over or under-damped. Then, at least one of the upstroke or downstroke damping factors of the wave equation model is adjusted so that new downhole data can be generated with appropriate damping.

Abstract: A pump apparatus has a downhole pump disposed in a wellbore and has motor at a surface of the wellbore, and the downhole pump is reciprocated in the wellbore by a rod string operatively moved by the motor. A card indicative of load and position of the downhole pump is generated using surface measurements and a wave equation model having a damping factor or two damping factors. Actual fluid load lines are determined from the downhole card for upstroke and downstroke of the downhole pump, and calculated fluid load lines from the load distribution of the downhole data. The actual fluid load lines are compared to the calculated fluid load lines so that at least one parameter of the pump apparatus can be modified based on the comparison. For example, the damping of the wave equation model can be adjusted so that another downhole card can be generated.

Abstract: A pumping control unit is disclosed herein. The pumping control unit includes a processor coupled to a memory and a communication interface. The memory is configured to store an invariant matrix. The communication interface is configured to receive a plurality of measurements of a time-varying parameter for a rod pumping unit. The plurality of measurements is taken at a surface of a pumping site over a pump cycle for a sucker rod string. The processor is configured to gain access to the invariant matrix in the memory and the plurality of measurements from the communication interface. The processor is further configured to compute a Fourier coefficient array based on the invariant matrix and the plurality of measurements. The processor is further configured to compute a time-varying downhole parameter based on the Fourier coefficient array and a sucker rod string model.

Abstract: It is an object of the invention to provide a pump jack pump-off control method and a pump jack control apparatus in which, even when the speed of a pump jack is reduced due to generation of a pump-off condition, the pump jack is not caused to stop due to the motor overload abnormality or the coagulated crude oil and, even when the pump-off condition is generated, the reduction of the production capacity of the pump jack can be prevented as much as possible. On detecting the pump-off condition, while the pump jack is in operation with the speed thereof being reduced, or while the pump jack is in operation at the lowest speed, according to the overload warning signal of an ac electric motor, the pump jack is switched over to its intermittent operation. Also, the pump jack can be operated in such a manner that the stroke speed of the pump jack in the up stroke operation can be switched from a sinusoidal wave form over to a rectangular wave form, or, in the operation of the pump jack by an inverter, the pump jack can be operated such that it can carry out its up stroke operation with a limit imposed on torque.
