Plugz-It Max is a lost circulation material designed to mix and pump with a drilling fluid into cobble, gravel, or fractured zones to restore mud circulation. It readily seals off coarse gravels, fractured formations, and other profiles where mud-loss is a problem. Plugz-It Max can be placed directly through the jets in the bit provided they are a minimum of 3 mm or 1/8” in size. Plugz-It Max is environmentally safe and non-toxic.
