Long Stroke Pumping Units

Forland Services has developed a new generation of long stroke pumping units that include a bi-directional motor and integrated control system. The units also feature a planetary gear box and open-looped chain/travelling sprocket transmission system, inner-tower counterweight system and a flexible load belt. The control cabinet includes an integrated power supply, VFD, PLC unit, human machine interface (HMI) module, physical indicators/buttons, and an optional remote access module.

The Forland long-stroke pumping unit  can achieve independent upward and downward stroke speeds. This is beneficial especially for heavy oil wells, horizontal wells and wells that are prone to gas lock. Additionally, stroke lengths are automatically adjusted and the working region of the stroke can be customized with no sacrifice to production capacity.

Besides slower operating speeds, which lead to fewer pump cycles and increased pump life, the unique selectable stroke section and independent controllable upward/downward speed makes the Forland unit highly efficient. It is able to solve complicated issues in high deviation, high fluid volume, high water-cut, and heavy oil conditions where other forms of lift tend to cause excessive down time.

In many applications, these units can eliminate the use of initial mid-sized ESPs and/or assist in transitioning from ESPs or from gas lift to rod lift sooner. For vertical wells where initial production is in the 700 to 900 bpd range, the Forland long-stroke unit is also efficient and can be installed during the first stage of lift, enabling consistent downhole equipment through the life of the well.
