Hydraulic fracturing in the United States, began in 1949. According to the Department of Energy (DOE), by 2013 at least two million oil and gas wells in the US had been hydraulically fractured, and that of new wells being drilled, up to 95% are hydraulically fractured.The output from these wells makes up 43% of the oil production and 67% of the natural gas production in the United States.

16/4/2020, · The ,fluid, density affects the surface injection pressure and the ability of the ,fluid, to ,flow back, after the treatment. Water-based fluids generally have densities near 8.4 ppg. Oil-base ,fluid, densities will be 70 to 80% of the densities of water-based fluids. Foam-,fluid, densities can be substantially less than those of water-based fluids.

Hydraulic ,fracturing, for natural gas extn. from shale produces waste brine known as ,flowback, that is impounded at the surface prior to reuse and/or disposal. During impoundment, microbial activity can alter the fate of metals including radionuclides, give rise to odorous compds., and result in biocorrosion that complicates water and waste management and increases prodn. costs.

Seawater is often used as a base ,fluid, to make hydraulic ,fracturing, fluids in offshore HF operations, whereas freshwater is most commonly used in terrestrial HF wells. The injected chemical additives (e.g., stabilizers) therefore also differ due to the use of seawater-based hydraulic ,fracturing, fluids as well as other constraints specific to offshore platforms.

The hydraulic ,fracturing fluid, usually carries proppant (typically sand) into the newly-created fractures to keep the fractures “propped” open. After hydraulic ,fracturing,, oil, gas, and other fluids flow through the fractures and up the produc tion well to the surface, where they are collected and managed. ­
