A pump jack includes a number of standard components that have been sized and configured according to unique relative dimensions to produce a pump jack that reduces structural stress, increases bearing life and permits a lower cost of manufacture. These geometric ratios can be used to express the relative size and spacing of the crankshaft, crank arms, center bearing, equalizer bearing, walking beam and pitman arms. Pump jacks incorporating one or more of these geometric ratios can be sized and scaled for a variety of pumping applications.

A computer-implemented method may comprise attaching a plurality of wireless sensors to a pump jack; receiving time-stamped data from at least some of the plurality of wireless sensors attached to the pump jack, at least one of the plurality of wireless sensors comprising an accelerometer and a gyroscope and being attached to a crank arm of the pump jack; synchronizing the received time-stamped data; from the synchronized time-stamped data, calculating and generating information related to: a downhole load versus polished rod position of the pump jack; a relative balance of a counterweight of the pump jack relative to a horse head of the pump jack; deviations from a nominal acceleration profile of a bridle of the pump jack; and an angle of inclination of the bridle of the pump jack; and selectively generating, on a computing device, visualizations of the generated information.

There are several methods to propel moving force points on a pumping unit. One of the embodiments is propulsion utilizing permanent magnets. This invention can aid the several methods and provides the push start that allows initiating permanent magnet propulsion. This invention relates to an end return device for assisting positioning drives to actuate the continuous movement by mechanical means of moving force points to a desired advantageous position at a desired advantageous moment to achieve reduced net torque when lifting or lowering an unbalanced load with a beam with a fulcrum and connected to a load and an effort. In one embodiment, a walking beam well pumping unit, the lifting and lowering of the well load can be caused by the reciprocating motion of a beam tipping on a fulcrum and with moving effort force point, moving crank shaft force point, and moving beam weight force point.

A pump jack includes a base, a pedestal supported by the base and a Samson post that supports a walking beam. The Samson post includes a front leg that is supported by the base and a connection bracket affixed to the front leg. The Samson post further includes an adjustable rear leg that is connected between the connection bracket and the pedestal. The rear leg can be rotated and shifted up and down within the connection bracket to ensure that the opposite end of the rear leg is properly located on the pedestal.

Embodiments of the present disclosure generally relate to apparatus and methods for counterbalancing a pumping unit. One embodiment of the present disclosure provides a method for operation a pumping unit. The method includes measuring an orientation of a component and one or more parameters of the pumping unit while running the pumping unit, and determining an imbalance of the pumping unit according to the measured orientation and one or more parameters.

A computer-implemented method may comprise attaching a plurality of wireless sensors to a pump jack; receiving time-stamped data from at least some of the plurality of wireless sensors attached to the pump jack, at least one of the plurality of wireless sensors comprising an accelerometer and a gyroscope and being attached to a crank arm of the pump jack; synchronizing the received time-stamped data; from the synchronized time-stamped data, calculating and generating information related to: a downhole load versus polished rod position of the pump jack; a relative balance of a counterweight of the pump jack relative to a horse head of the pump jack; deviations from a nominal acceleration profile of a bridle of the pump jack; and an angle of inclination of the bridle of the pump jack; and selectively generating, on a computing device, visualizations of the generated information.

A downhole pump barrel is nickel plated to a predefined thickness followed by Boronizing a portion of nickel matrix to create Nickel Boride layer and leaving a layer of nickel between the newly formed Nickel Boride and the barrel metal surface. The top layer of Nickel Boride provides a hard surface like chrome plating which increases the wear/abrasion resistance during the sucker rod pump production. The nickel matrix disposed beneath the Nickel Boride acts as a barrier from any corrosion attacks reaching the barrel metal surface.

A horsehead is used on a walking beam of a reciprocating pump unit. The horsehead includes side plates, a face, tabs, and brace plates. The side plates are spaced apart, and the face affixed to front, arced edges of the side plates. The face defines a split therein extending from a bottom end toward a top end, and the tabs are affixed to the face across the split. The face thereby defines two runner surfaces. A fixture at the top end of the face can be used for connection to a bridle of the pump unit. The brace plates are connected in the space between the side plates and are arranged in a lattice structure. Preferably, the brace plates include cutouts to reduce weight.

An assembly is used to connect an equalizer bar to a walking beam of a reciprocating pump unit. The walking beam has a bearing shaft having cylindrical ends. Brackets attached to the equalizer bar define slots, each having a hooked section and having a base section. The hooked sections are configured to rest against the cylindrical ends of the bearing shaft. The base sections of the slots oppose the hooked sections at a gap from the cylindrical ends of the bearing shaft. Wedges are configured to position in the slots between the bases and the cylindrical ends of the bearing shaft.

A system and method controls a plurality of artificial lift units at a plurality of wellsites. Processing equipment installs at a plurality of the wellsites. Operating parameters of each of the artificial lift units are obtained with sensing equipment at the wellsites and are communicated in real-time from the wellsites to the installed processing equipment at the plurality of the wellsites. A modelling function of the processing equipment analyzes a trend of the operating parameters of the artificial lift units, and automated machine learning of the processing equipment predicts a condition of at least one of the artificial lift units based on the analyzed trend. The processing equipment determines at least one automated control for the determined condition of the at least one artificial lift unit and counters the determined condition by implementing the at least one automated control at the at least one artificial lift unit.
