Beam Pumping Units typically deploy a downtime or dwell period methodology to reduce the average SPM (Strokes Per Minute), as opposed to changing sheaves, belts, crank pin positions, etc. While this may be acceptable for many beam unit applications (although not ideal), the downtime during a pumped off condition allows solids to settle down and on top of the bottomhole pump, potentially sticking the pump. This can lead to increased well failure frequencies and higher pulling costs, which CAN be reduced, if not avoided. Another potentially more detrimental issue (financially speaking, especially with higher oil prices), is the retardation effect to production rates. To prevent over pumping in a pumped-off (gas & fluid-pound) condition the beam unit is stopped, often for long durations to allow the formation reservoir pressure to refill the well bore anulus. The unit it then restarted and the well is then pumped off, once again. These fluid level fluctuations in the well bore drive up pressures against the reservoir, holding fluid back that could otherwise be produced.
Unlike a beam unit, the HRP unit's stroke rate can be altered remotely via an intuitive Windows based software package. By reducing the strokes per minute (SPM) under a pumped off condition, the well is kept operational thus reducing the time for solids to settle. This fine tuning of the pump rate also maintains a consistent reservoir pressure allowing for more predictable fluid flows.
For large changes in well properties, the HRP unit's motor/pump and hydraulic cylinder combinations can be changed relatively easily when compared to beam units. Once a well is designed there is rarely a need to alter the pump, motor, cylinder configuration. HRP Power Units can also be moved easily from one well to another by simply replumbing the hydraulic lines, or by moving the unit itself. Portable trailer mounted units are also available.

Fluid Level (blue) vs. SPM (green) The SPM can be fine tuned to maintain the desired Fluid Over Pump. Notice that increases in SPM result in decreased fluid level (and vice versa). |
