The ,fracturing fluid, carries the proppant into the fractures and releases the proppant, thus propping open the fractures and allowing oil or gas to flow through the fractures and into the well. Slickwater ,fracturing, is not universally applicable—in some formations, gel treatments or “acidization” to weaken the rock are more effective techniques.
