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. Oil ...

These tests provide a superior method of measuring fracture closure pressure in low permeability formations, especially when mud is used as the injection ,fluid,. In a pump-in and ,flow-back, test, wellbore pressure and ,flow-back, time/volume are recorded.

completed, fracturing fluid flows back to the surface along with gas and oil. The flowback and produced waters are collectively called “HF water”. This flowback fluid and water that remains underground is a great threat to the environment and is estimated that only 5-60% of the fracturing fluid flows

Figure 5 shows the profiles of temperature along the fracture wall during the periods ,of fracturing,, shut-in, and ,flowback,. During the ,fracturing, period, the results show a cool-down process, which is described by a decreasing fracture temperature. The maximum temperature drop is about 50 °C in the fractures.

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 ].

Case Study: Frac Water Reuse Technologies

Generally, 20-40% of the fracturing fluid volume is recovered as flowback. Produced water is the water which naturally exists within shale formation and is recovered concurrently with oil and gas. After the initial flowback period, produced water resembles the characteristics of the formation brine.

The blue arrow in Fig. 8 demonstrates the mixing trend from slickwater‐dominated ,flowback, samples (,fracturing fluid,) toward increased contributions of primary formation water. The presence of a complex fracture system is suggested by the irregular ,flowback of fracturing, fluids, as evidenced by a peak volume of recovered KCl brine on January 5, 2013, and January 29, 2013 (Birkle 2016 ).
