Further research disclosed that ,pumping, out ,sand, opened "wormholes" in the ,sand, formation which allowed more oil to reach the wellbore. The advantage of this method is better ,production, rates and recovery (around 10% versus 5–6% with ,sand, filters in place) and the disadvantage that disposing of the produced ,sand, is a problem.

Fracking Sand: What Is It? - The Balance

Fracking ,sand, is a proppant—a material used to prop open the underground cracks from which the oil and natural gas can then be harvested during the fracturing ,process,. These rocky areas don't have enough pore space to allow fluids to flow to a wellhead and be brought to the surface.

If the ,pumping process, shears gel with a reduction in viscosity. then ,sand,-carrying capacity is lowered. Lower get capacity could cause ,sand, fallout during ,pumping, and placement, resulting in premature sandouts in the pump, deviated sections of the drillpipe (tubing), the crossover tool, or the fracture.

Sulphuric acid is the most commonly used acid in industry. It is used in the ,production, of fertilizers and as an electrolyte in car batteries. Sulphuric acid in contact with skin will cause severe burns; therefore, it is important to set up the ,production process, in such a way that the risk of leakage when ,pumping, chemicals is eliminated.
