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.

hydraulic fracturing flow-back water is approximately 85%. Therefore, it only needs 15% of freshwater to continue fracturing process each day, and photo-Fenton and floatation would be an excellent method to remove solids and chemicals from flow-back water. Furthermore, the percentage of …

On the other hand, if the permeable pathway intersects the aquifer far away from the pumped wells, HF ,fluids, could ,flow back, down the permeable pathway. Since this distinction would require additional parameters to be varied, we employ TTA as a conservative metric of HF fluid reaching the aquifer and do not consider the influence of the flow within the aquifer.

The fracturing fluid that comes back from the downhole contains a mixture of chemicals, water, sand, salt, gas and oil. EPA regulations require operators to capture and monitor as much of the flow back liquids as possible to protect the environment. After the shaker process (removing as much of the solid proponent) the collectio of the liquids to ...
