However, in most cases, only 20-40% of the ,carrying fluid, flows back to the surface and the rest remains deep in the ground. Initially, the technology used 20,000 to 80,000 gallons of water per well, but today’s advanced fracturing techniques can use up to 8 million gallons of water and 75,000 to 320,000 pounds of ,sand, (proppant) per well.

All of the systems basically were slurries of gravel and liquid plastic in a viscous ,carrying fluid, such as a refined neutral oil. Other systems placed the gravel and plastic with diesel oil by ,pumping, at relatively high rates until the pack was complete, then a catalyst solution was injected to harden the plastic after any excess gravel had been removed from the wellbore.

carrying fluid, in very heavy slurry is just a necessary evil in helping to transport the desired material. The medium (Class 2) and heavy slurry (Class 3) fall somewhere in between. The optimum slurry pump material will often vary even across a single processing plant that is transferring the same solids (but having different sizes).
