A downhole reciprocating pump configured for deployment within a tubing string. The reciprocating pump includes a pump barrel, a plunger inside the pump barrel, a lower seating nipple connected within a lower portion of the tubing string and a lower hold-down connected to the pump barrel. The lower hold-down is configured for a mechanical latching engagement with the lower seating nipple. The reciprocating pump also includes an upper seating nipple connected within the tubing string above the lower seating nipple. The upper seating nipple is longer than the lower seating nipple. The reciprocating pump further includes an upper hold-down that has one or more seals that contact an interior surface of the upper seating nipple.

A long-stroke pumping unit includes a tower; a counterweight assembly movable along the tower; a crown mounted atop the tower; a sprocket supported by the crown and rotatable relative thereto; and a belt. The unit further includes a motor having a stator mounted to the crown and a rotor torsionally connected to the sprocket; and a sensor for detecting position of the counterweight assembly. The pumping unit may include a dynamic control system for controlling a speed of a motor.

A mechanical rod rotator assembly comprising a mechanical rod rotator and an actuating mechanism for a mechanical pumping rod rotator, wherein the mechanism comprises a connecting arm and a guide member that slidably embraces the pumping rod, in order to allow a pivoting lever that is in connection with said connecting arm, to interact with the internal mechanism of the rod rotator to gradually rotate the pumping rod and thus avoid impartial wear caused by the constant up and down reciprocating movement of the same within the well, being in turn that the mechanism of the invention does not require special tools for its assembly and installation.

A polished rod elevator has a top lift platform defining a polished rod passage and a mouth to laterally receive a polished rod into the polished rod passage; a plurality of linear actuators depending below the top lift platform and radially spaced from an axis of the polished rod passage to define a production tree receiving gap; and a plurality of arcuate wellhead flange mounting base plates connected to base ends of the plurality of linear actuators. Related methods of use and kits are discussed.

An improved system and method for managing and distributing electrical power is provided. In various embodiments, systems and methods comprise at least one powered device that receives electrical power from at least one source. Structure and devices are provided within the system to monitor, regulate, and transmit power from a source to a powered or driven device in an efficient and reliable manner based on availability, cost, and environmental factors.

A methodology for integrated pump and well data for managing pump-lifted wells in hydrocarbon fields is provided. Rod pumps are widely applied to various types of wells to provide uplift and may play a dominant role in the flow of hydrocarbon from reservoir to surface. Assess the state of each well and its components (including the associated rod pump) is important for optimal well and reservoir management for fields with artificially lifted wells. As such, a methodology is disclosed that performs machine learning in order to generate a machine-learned model using pump card data and at least one of well data, reservoir data, flowline data, user input data, or data generated from analysis of one or more of the well data, the reservoir data, the flowline data, or the user input data.

Embodiments of the present disclosure generally relate to a pumping unit base and methods for operating with the pumping unit base. The pumping unit base may include a plurality of driven piles installed in the ground, and a metal platform fixedly attached to the plurality of driven piles, wherein the metal platform is positioned above the ground. The metal platform may be removed from the driven piles and reinstalled to the driven piles.

A powered well string positioner capable of actuation during the vertical reciprocal movement of a well string will increase or decrease the length of the downhole well string length below the wellhead seal upon detection of a string positioning condition within the tubular by a controller. The vertical reciprocal stroke of the power unit of the well is not changed as the downhole length of the well string is varied, and the well string can be adjusted during operation of the well without the need to disassemble the well string.

Sensor systems for sucker rod pump systems and gear rod rotator systems may include one or more sensor modules comprising a sensor including at least one of a position sensor, a temperature sensor, a pressure sensor, or a vibration sensor for detecting a characteristic related to at least one component of the sucker rod pump systems or the gear rod rotator system.

A computer-implemented method for determining an operating property of a pumpjack, wherein the pump has a pump head, which is connected to a kinematic converter via a rod system, and the kinematic converter is driven by a motor during operation and a load-travel graph containing curve points is determined for the delivery pump by an analysis device using recording and is provided as an operating load-travel graph containing operating curve points.
