In a conventional, well, completion, the, flowback, period (also known as well cleanup) may involve flaring or venting of produced gas to the atmosphere via an open pit or tank collecting the, fluids. Well, completions that involve hydraulic, fracturing, result in a higher rate of, flowback, than most conventional, well, completions, due to the large quantities of water and proppant (mainly sand) used to fracture …

Once the pumping is halted, the, pressures, inside a fracture subside as the fluids either flow back into the well or leak away into the reservoir rock. This drop in pressure allows the fracture to close again. To ensure that fractures stay open, engineers inject additional materials, depending on lithology.
