G-Stop is a polymer that will expand 300 times its volume in freshwater (50 times in salt water). This remarkable property makes it an excellent medium for plugging fissures and cracks encountered in drilling operations preventing the further loss of drilling fluid.

Features & Benefits
- Stop lost circulation to formation by plugging fissures in rock
- Bond loose rock together end prevent sloughing
- Provide lubrication in loose, abrasive broken ground conditions
Mixing & Handling
Mix the G-Stop directly in the tank with 200 times its volume water. Wait 10 minutes. Inject the mixture into the drill string. Inject a volume of water to move mixture to the correct location. Wait 20 minutes. Drill. If the problem persists attempt treatment a second time.
or
Place 1 gallon of dry G-Stop in a 20-liter pail with 10 liters of water. Allow G-Stop to partially swell. Add 1 liter of partially swollen G-Stop to the rods after the core tube has been pulled. Pump down hole and replace inner tube. Repeat as necessary to stop loss.
