Primary Focus
• What if you could help eliminate rod parts and tubing
leaks?
• What if you could lower your chemical cost and
downtime?
• No more batch treatments and shutting wells in.
• Reducing failure rates and improving well profits!!!

multiple turns to set
• Cannot get capillary
through it
• Everything below it
exposed to well
conditions
