often so high that if the ,flowback, water was ,discharged, to a wastewater ,treatment, facility, the effluent from the plant would breach the discharge permits. High chloride levels can also cause specific chemical reactions to occur during water ,treatment,, resulting in harmful byproducts. If left untreated and released

Seismic Survey - an overview | ScienceDirect Topics
Seismic Survey - an overview | ScienceDirect Topics

Seismic surveys are conducted by deploying an array of energy sources and an array of sensors or receivers in an area of interest. Figure 3.9 shows a ,seismic survey, on land. The source of seismic waves is either an explosive which directly generates the seismic wavelet or a mechanical source which is commonly a vibrator, which uses a steel base plate in contact with the ground and transmits ...

After, fracking, roughly 35% of the water returns to the surface as ,flowback, in the first weeks. Additional liquid known as produced water—a mix of fracking ,fluid, and groundwater—comes up with ...

Recovered Water Management Study in Shale Wells
Recovered Water Management Study in Shale Wells

After a shale well has been hydraulically fractured, produced and flowback water returns to the surface inside a steel pipe. For the scope of this study, all fluids (including flowback and produced water) that flow back to the surface in the first weeks to months after the fracturing of a shale well, are considered to be recovered water.

This mixture, called ,fracturing fluid,, creates fissures in the shale increasing its permeability and gas recovery. The mixture of the injected ,fracturing fluid, together with the connate water of the formation, which returns to the surface within few weeks ,after, pressure being released, is called ,flowback, water (Olmstead et al., 2013).

form the fracturing fluid. Most of the used water is discharged in the form of a flowback wastewater. In principle, the flowback wastewater can be treated and reused to reduce freshwater consumption. The objective of this research is to develop a framework for the logistics and scheduling of a mobile treatment system for multiple producing wells.
