... locally charges the rock porosities and "pops" the rock chunks loose. The second process basically involves a brute force approach, which uses a hard material (sand, proppant, garnet, etc.) to impact and abrade the rock surface. The abrupt turn of the jet's stream causes the abrasive to contact...
