During the hydraulic ,fracturing, process, the ,fracturing fluid, may cause water retention, if the nearby secondary fractures subsequently close and get disconnected due to changes in effective stress distribution during ,flowback, and prodn. The circumstances and detailed mechanisms assocd. with this phenomenon are still poorly understood.

Hydraulic fracturing - Wikipedia

Hydraulic fracturing,, also called fracking, fracing, hydrofracking, fraccing, frac'ing, and hydrofracturing, is a well stimulation technique involving the ,fracturing, of bedrock formations by a pressurized liquid. The process involves the high-pressure injection of "fracking ,fluid," (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore ...

During oil and natural ,gas production,, so-called “produced ,water,” comprises the largest byproduct stream. In addition, many oil and gas operations are augmented via injection of hydraulic ,fracturing, (HF) fluids into the formation. Both produced ,water, and HF fluids may contain hundreds of individual chemicals, some known to be detrimental to public health and the environment.

Environmental impact of hydraulic fracturing - Wikipedia

The environmental impact of hydraulic ,fracturing, is related to land use and water consumption, air emissions, including methane emissions, brine and ,fracturing fluid, leakage, water contamination, noise pollution, and health.Water and air pollution are the biggest risks to human health from hydraulic ,fracturing,. Research has determined that human health is affected.
