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.

separating/re-pressurizing the flow -back CO 2. The framework is driven by physics-based process models that represent the different processes for injecting sCO 2 and water, generating/propagating fractures, extracting CH 4 and heavier hydrocarbons from the shale formation, and removing hydrocarbons and additives from the flow back sCO 2 and water.

Fracturing fluid interacts with the reservoir rock and the formation water, resulting in high contents of suspend solids and dissolved solids in the flowback fluid; this can seriously affect the gelation and cross-linking of the gel during the recycling and reusing process.

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.
