Down Hole Equipment

• Flexible steel band up to 1500 m of length
• Steel band surface sealing
• Plunger for working straight into the tubing

Surface Unit

• Large diameter traction wheel for 1500 m steel band.
• High torque motor and variable pump hydrostatic transmission.
• Electric motor or diesel engine prime mover.
• Control and supervision from onshore control central via modem, either by wire, satellite or radio.
• Operators terminal for selection of plunger's depth, stroke length, velocity up/down, etc.
• Bar graph indicates plunger's travelling position.
• Alarm system supervises the operation and continuously indicates the current status.

Highlights

• 1500 m plunger depth and 200 m active stroke length.
• Flexible steel band permits 30 degree elevation of tubings.
• Soft change of direction, smooth acceleration and deceleration of the traction wheel.
• Disc brake stops the traction unit immediately if plunger meets an obstruction.
• Detection and early warning alarm, should paraffin or asphalt being built up.
• Long stroke eliminates spring effect.
• Swabbing effect due to continious pump flow.
• Reduced influence of gas break outs.
• Longer life time due to reduced cycle periods and load variations.
• Light workover and plunger repair by spooling the entire steelband and the plunger up to surface.
