A Scale Knocker plunger removes scale from the seating nipple to improve production. If a well's production is restricted by severe scale build up in the seating nipple, we suggest our Scale Knocker Plunger. It removes scale to maintain or improve production.

A Scale Knocker Plunger is a variation of the Shock Absorber Plunger. It has an additional 'stinger' that penetrates the seating nipple on contact to remove scale before it can build up. This plunger can be run daily or as needed for scale removal. Its usage can reduce chemical treatment and wireline expenses.

Applications

• Wells with scale build-up in the seating nipple

Advantages

• Does not require bottom hole bumper spring
• Reduces costs for chemical treatments or wirelines
• Removes and prevents severe scale
