gas or fluid flows due to blowouts or spills, leaking fracturing fluid, and uncontrolled waste water discharge. High water consumption: 15,000 m³ per well (Barnett Shale, USA), increasing regional water consumption by one third. Fracturing fluids contain hazardous substances, and flow-back in addition contains heavy metals and

“In the ,field,, such surfactants penetrate the formation and displace the ,oil, from the surface so it can flow into the fracture network. Because that fracture network is water-wet, it acts as a slick, ,oil,-repelling highway that encourages the ,oil, to move into the wellbore, increasing production and …

Fracking - Beachapedia

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 …

Hydraulic fracturing fluid migration in the subsurface: A ...

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 ].

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.

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., ).
