Abstract: A data communications system and method for transmitting data over a string between a surface location and a sub-surface location in a well bore in which a load varying device at the sub-surface varies the mechanical load on the string to be indicative of the data and a load measuring apparatus at surface monitors the mechanical load on the string and decodes the data. Data transmission is described from a pump assembly through a sucker rod string. Embodiments of load varying devices using electrical generators, friction rollers and hydraulic and pneumatic brakes are also described.

Abstract: Diagnosing a pump apparatus having a downhole pump disposed in a deviated wellbore characterizes axial and transverse displacement of a rod string with two coupled non-linear differential equations of fourth order, which include axial and transverse equations of motion. To solve the equations, derivatives are replaced with finite difference analogs. Initial axial displacement of the rod string is calculated by assuming there is no transverse displacement and solving the axial equation. Initial axial force is calculated using the initial axial displacement and assuming there is no transverse displacement. Initial transverse displacement is calculated using the initial axial force and the initial axial displacement. Axial force and friction force are calculated using the initial displacements, and the axial displacement at the downhole pump is calculated by solving the axial equation with the axial force and the friction force. Load at the downhole pump is calculated so a downhole card can be generated.

Abstract: An instrumentation system for assessing operation of a reciprocating pump system which produces hydrocarbons from a non- vertical or a vertical wellbore. The instrumentation system periodically produces a downhole pump card as a function of a directly or indirectly measured surface card and a friction law function from a wave equation which describes the linear vibrations in a long slender rod. A control signal or command signal is generated based on characteristics of the downhole pump card for controlling the pumping system. It also generates a pump and well analysis report that is useful for a pump operation and determination of its condition.

Abstract: A method and apparatus for vertically adjusting the stroke of the polished rod (2) of a pumpjack during its operation in a producing well, while detecting abnormal conditions such as gas-off, pump seizure, sucker and separation, gas-lock pounding or fluid pounding. The method and apparatus involves a hydraulic or pneumatic cylinder (17) interposed between the polished rod clamp (1) and the carrier bar (19) of the pumpjack. Abnormal conditions are detected by an electronic device incorporating a pressure transducer which senses fluid pressure changes in the hydraulic or pneumatic cylinder (17), converts the pressure changes into electrical voltages, and then determines if an abnormal condition is present. If an abnormal condition is sensed, the pumpjack can be stopped, and restarted automatically after a momentary interval in the event of gas-lock or fluid pounding, or manually after inspection by an operator in the event of a more serious condition.

Abstract: Apparatus and methods are disclosed for controlling the operation of a rod-pumped oil well using calculated downhole performance of the subterranean pump (6). The surface load and position are measured at equal increments of time. The measured load and position values, in combination with physical parameters of the pumping system, including the size, weight, elastic properties, and length of the rod string (4), are used by one of three preferred mathematical-analysis techniques (figs 9-11) to construct a downhole dynagraph plot of load versus position over time as it exists at the subterranean pump (e.g., 110 or 111). The characteristics of the downhole dynagraph are then analyzed by one of a plurality of algorithms (figs 7 or 8) to detect pump-off or other pump problems.

Abstract: A system for controlling production in an oil well comprises a controller (36) for activating the means for causing reciprocation (37) of the sucker-rods (21); a sensing means (30) secured to the outer surface of the production tubing (14) near the lower end thereof comprising a radioactive source (28) spaced from a radioactivity detector (45) such that oil at that level will fill the said space, means associated with said radioactivity detector for counting (50) the output of the detector and establishing an "off signal" when the frequency of the output is indicative of no oil in the said space; means for converting the "off signal" into an acoustical signal (46) directed up the borehole; and receiving means (35) at the top of the borehole for detecting the acoustical representation of the "off signal" and transmitting it as an electric signal to said controller (36).

Abstract: A well pump includes a Sampson post (2) supporting a walking beam (1) which oscillates to cause a horsehead (3) to operate one or more sucker rods in a well bore. The invention avoids need for a flywheel, gearbox or other mechanical means connected to the base to cause or control oscillating motion of the walking beam. A carriage (5) movably supports a balance mass (4) on the walking beam and is positioned by a hydraulic cylinder (6) or other positioning means to change the relative position of the balance mass, thus causing oscillation of the walking beam. A moving mass control system (11-21) regulates the positioner means and the stroke timing thereof so that a wide range of variable operating conditions can be instituted. One embodiment includes a walking beam (1') adapted for connection at its ends with sucker rods (53a, 53b) in different well bores.
