Between 10-30 percent of this water flows back to the surface as a waste product that must be collected and disposed of properly. Much like produced water, flowback fluids are then routed to production tanks for storage prior to disposal.

proved in American research, the amount of the fluid obtained in shale gas fracturing is lower than in the case of a tight oilfield: 40-60% for a vertical well and 10-30% for a horizontal well [11, 12]. The majority of flowback water outflow takes place during the first hours to a dozen or so days. During contact with the deposit, the fracturing fluid

How much water does hydraulic fracturing use,? The average fracking job uses roughly 4 million gallons of water per well – or about as ,much, water as New York City uses every six minutes and about 1.3 percent of the water used by the country’s car washes every day.That can vary by state, because the amount of water used in each hydraulic ,fracturing, job depends on geology and a number of ...

Hydraulic Fracturing and its Impact on Water Resources

Vital to the fracking process are the millions of gallons of fracking fluid for each well, a fluid made up of over 90 percent water. While each company’s formula is a closely guarded secret, a review of the recognized 1,021 chemicals in these various proprietary mixes are known to include surfactants , biocides and even toxic substances like volatile organic compounds and carcinogens.

Fracturing fluid, migration is a multiphase flow problem in which gas or oil (the nonwetting phase) contained in the shale interacts with HF ,fluid, or brine (the wetting phase). Most shale gas plays have low brine saturation (0.1–0.5), which gives rise to a number of multiphase flow effects such as capillary imbibition and reduced relative permeability [ Byrnes , 2011 ; Engelder , 2012 ].

Fracturing-fluid flowback is simulated with the use of a developed simulator. A hydraulically fractured horizontal well with a 1200 m horizontal wellbore and 15 fracturing stages situated in the center of a shale reservoir (1500 m × 560 m × 40 m) is considered. The initial reservoir pressure is 25 MPa.
