DD XPAND (fine and coarse)




DD XPAND is an environmentally safe, loss circulation, and plug material which can be used in the diamond, rotary, and seismic drilling industries. DD XPAND allows drilling through highly fissured and fractured formations and can effectively shut off water flows.




DD XPAND should be mixed in the form of a slug at approximately 2 to 4 pounds per 100 gallons of fresh water (2.5-5.0 kg/1000 liters). Let stand for 15 minutes, then inject mixture into the rod string, moving the slug to the problem area. Wait 20-30 minutes, then drill. This procedure may have to be repeated if fissures are large. The slug, once at the problem area, will further expand, using up the water in the fissures or cracks, sealing off either lost circulation or incoming water.




2-4 pounds of DD XPAND per 100 gallons (2.5-5.0 kg/1000 liters) of water.




No special precautions are necessary.
