Overview

  • Variable stroke up to 9.3 meters
  • Lifting capacity up to 80,000 Ibs.
  • Variable lift capability from 35,000 to 80,000 Ibs.
  • Variable speed up to 4.5 SPM
  • Highly efficient
  • Independent speed for up and down strokes
  • Automatic speed adjustment for up and down strokes based on well situation
  • Integrated control system
  • Inherent braking system
  • Small footprint

Features and Benefits

  • Lighter weight
  • Counterbalance adjustment without shutdown
  • Easy control for stroke speed, stroke length and stroke position
  • Long stroke based on lower speed
  • Slower down stroke to reduce the buckling
  • No crane required for work-over
  • Optimize well production without shutdown
  • Automatic / Independent variable speed for up or down strokes
  • Fewer cycles to reduce failures and repairs

Safety

  • Less injury pinch-points compared to Belt-Driven unit
  • No manpower required for counterbalance adjustment compared with Belt-Driven unit

Economical Advantages

  • Installation and commissioning cost saving
  • Minimize well interventions
  • Operating expense cost saving
  • Transportation cost saving
  • Production cost saving
  • Power supply cost saving
  • Fewer cycles to increase downhole pump, tubing and rod string shelf life

Applications

  • Hight-Volume, depth and highly challenged wells
  • High asphalt & sandy wells
  • Directional and horizontal wells
  • High gas content (GOA) and heavy oil wells
