Progressive cavity pump system having reverse mode

A progressive cavity pump (PCP) system includes a PCP with a rotor rotatably disposed in a stator, a permanent magnet motor, sucker rod(s), and a control system. The rotor is coupled to one of the sucker rods via a high-torque connection that allows for counter clockwise rotation without loosening the connection between the rotor and sucker rod. The control system operates the system in a production mode by rotating the rotor clockwise. Upon manual input by a user, or automatic triggering when protections settings of the control system call for a shutdown or cleanout or when the control system senses an imminent pump shutdown, the control system operates the system in a reverse mode by rotating the rotor counterclockwise. The reverse mode pumps fluids and suspended solid particles down into the well prior to pump shutdown to inhibit the solids from clogging the pump or preventing the pump from restarting.

OIL WELL DOWNHOLE LIQUID INJECTION ASSEMBLY

... "OIL WELL DOWNHOLE LIQUID INJECTION ASSEMBLY" ABSTRACT OF THE DISCLOSURE A downhole pump is actuated by a reciprocating unit comprising a tubular rod string, a valve assembly, and a tubular plunger rod. A flow passage extends through the reciprocating unit when the valve assembly is in an "open" position, whereby liquid may be injected into the pump barrel chamber to ensure the presence of incompressible fluid in the chamber from the beginning of the up stroke, to thereby reduce or eliminate gas locking of the pump. The valve assembly, which moves together with the reciprocating unit of which it is part, is adapted to interact with a stop member on the stationary pump barrel, to initiate opening of the valve as the rod string approaches the bottom of its stroke. The valve assembly is further adapted to automatically close when lifted away from the stop shortly after the beginning of the up stroke. The valve thus remains open only during the bottoming out phase of the stroke, when only limited ...

ULTRASENSITIVE APPARATUS AND METHOD FOR DETECTING CHANGE IN FLUID FLOW CONDITIONS IN A FLOWLINE OF A PRODUCING OIL WELL, OR THE LIKE

ULTRASENSITIVE APPARATUS AND METHOD FOR DETECTING CHANGE IN FLUID FLOW CONDITIONS IN A FLOWLINE OF A PRODUCING OIL WELL, OR THE LIKE Transient change in heat flux due to ultrasmall variation in flow conditions, say from flow-to-no flow within a flowline of a wellhead connected to an oil well penetrating an earth formation, is surprisingly useful in pinpointing the occurrence of adverse "pump pounding" during the production cycle of the well. In one respect, the change in flux is monitored within each flowline using a heat flux transducer/ meter in series with a pump controller. Cascading the signal output, i.e. serially combining the outputs of N thermocouples the transducer/meter, enhances sensitivity. In a preferred case, N is about 80 but can be as high as 320, if desired.

OIL WELL PUMPOFF CONTROL SYSTEM UTILIZING INTEGRATION TIMER

OIL WELL PUMPOFF CONTROL SYSTEM UTILIZING INTEGRATION TIMER. A valve in the production flow line of an oil well closes a reed switch indicative of fluid being pumped through the line. The switch closure activates a first oscillator whose count is compared with a variable frequency oscillator having a frequency of approximately one-half that of the first oscillator. The comparison is made over a given period of time to ascertain the percentage of time the valve has been open and passing fluid. Theoretically, the valve should be open approximately fifty percent of the time because almost that much time is taken on the downstroke of the pumping assembly when no production is occurring. The integrated timer is adjusted to shut down the system when the percentage of time the valve is open drops to the preselected amount, usually equal to or less than around fifty percent. In response to the integration timer producing a signal, a shutdown timer is turned on which restarts the cycle after a preselected ...
