Hydraulic ,fracturing, is a controlled, high-pressure injection of ,fluid, and proppant into a well to generate fractures in the rock formation containing the ,oil, or ,gas,. After the hydraulic fracture procedure is completed, the injected ,fluid, is allowed to ,flow back, into the well, leaving the proppant in the newly created fractures.

Hydraulic fracturingis a well stimulationtechnology used to maximize the extraction of underground resources; including oil, natural gas, geothermal energy, and even water by fracturing the formation to create enhanced pathways for the fluids to flow into gathering wells.

The fracking process occurs after a well has been drilled and steel pipe (casing) has been inserted in the well bore. The casing is perforated (has holes or slots) within the target zones that contain oil or gas, so that when the fracturing fluid is injected into the well it flows through the perforations into the target zones.

This water comprises both ‘,flow-back,’, i.e., returned drilling and hydraulic ,fluids,, in addition to ‘produced’ water, consisting of formation brines from the hydrocarbon reservoir and extracted along with the ,oil, and ,gas,. The proportion of ,flow-back, and produced water from a given well changes over time with the latter making a greater contribution (>90%) as the asset ages (e.g., ).

After the shale has been fractured, the fracturing fluids flow back up the well to the surface along with the gas and highly saline brines from the shale formation. The process is contained but some people fear that toxic fracturing fluid chemicals in this flowback could contaminate nearby water supplies if they're accidentally spilled or insufficiently treated before being disposed of.

26/3/2015, · Hydraulic ,fracturing, techniques are particularly effective in enhancing ,oil, and ,gas, production from shale ,gas, or ,oil, formations. Until quite recently, shale formations rarely produced ,oil, or ,gas, in commercial quantities because shale does not generally allow the flow of hydrocarbons to wellbores unless Start Printed Page 16131 physical changes to the properties of the rock can be induced.

The difference between flowback water and produced water is the time spent in the well; flowback water usually refers to the return of injected fluids following hydraulic fracturing, while produced water is formation water that is high in gas and oil or water produced due to the pumped abstraction of water directly from coal beds.
