FracPoint with IN-tallic™ Frac Balls

IN-Tallic™ Disintegrating Frac Balls & Seats

• HP/HT Tripping Balls which degrades over time after the wellhas been stimulated

• Provides assurance that all restrictions are removed from theproduction string without costly interventions

• Reacts with flow back water from formation salts fordisintegrating.
