    Abstract: A method for calculating a downhole card for an oil and gas well includes setting a damping factor to an initial value, calculating a downhole card using the initial load value, and determining whether the difference between a true load value and an effective load value is within a desired error tolerance. If not, the method can also include setting a new damping factor to a value equal at a mid-point between the initial damping factor and a damping factor bound, recalculating the downhole card using the new damping factor, and determining whether the difference between a new true load value and a new effective load value is within a desired error tolerance. If not, the method can also include setting the new damping factor to a value equal at a mid-point between the previous damping factor and a damping factor bound.

    Abstract: An oil well pumping unit. The pumping unit has a vertical support column residing adjacent a horizontal support base at a generally transverse orientation. The pumping unit has a standing sheave fixed proximate an upper end of the vertical support column, a carrier bar attached to a polished rod along the front face of the vertical support column, and a traveling sheave configured to move up and down along the vertical support column. A near-vertical actuator resides along the horizontal support base, and is connected to the traveling sheave. Cyclical movement of the linear actuator causes the traveling sheave to reciprocate up and down such that upward movement of the traveling sheave produces a downstroke of the polished rod, while downward movement of the traveling sheave produces an upstroke of the polished rod. The linear actuator remains in tension at all times during movement of the polished rod.

    Abstract: 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.

    Abstract: A rod-pump control device is disclosed. The rod-pump control device uses AMP (current) measurements for electric units, fuel or air usage for gas units, and can use pressure for either unit. The AMP/fuel/air sensors work as the primary trigger to indicate a pump-off condition on an oil and gas well. These sensors can be used as stand-alone triggers or in conjunction with other sensors to more accurately monitor pump efficiency. When the pump-controller starts to indicate an inefficient pump condition, it will turn the pump off by removing power from the electric motor. For gas powered units, the controller will remove power to disengage an electric clutch or send a signal to an engine controller to stop. An adjustable algorithm will use percentage change of off time, dependent on actual run time compared to a user definable target time to keep the pump operating at peak efficiency.

    Abstract: Systems and methods for providing power to devices at a well site employ a linear alternator to generate power at a well site. The linear alternator is mounted on a pump at the well site and uses the up-and-down motion of the pump to generate power. The pump may be a nodding donkey head pump or other sucker rod pump mechanisms that operate based on linear vertical motion. The linear vertical motion drives a linear rotor back and forth through a linear stator to induce current in the linear alternator. This allows the linear alternator to convert a portion of the mechanical work performed by the pump into electrical energy that can be supplied to the devices. In some embodiments, the pump-mounted linear alternator can be equipped with a position sensor to directly measure a vertical position of the pump as the alternator travels up and down with the pump.
