26/4/2017, · Hydraulic ,fracturing, is the process of pumping a ,fluid, into a wellbore at an injection ,rate, that is too great for the formation to accept in a radial flow pattern. As the resistance to flow in the formation increases, the pressure in the wellbore increases to a value that exceeds the breakdown pressure of the formation open to the wellbore.

Hydraulic ,fracturing, of shale is most commonly performed through the introduction of large volumes (c. 5000–20 000 m 3) of aqueous ,fracturing fluid, at sufficient ,rate, and pressure to break the hydrocarbon-bearing formation and increase its permeability for optimal flow rates of gas and liquids into the well bore (Arthur et al., 2008; Gregory et al., 2011).

To help diagnose the impact of a frac hit on ultimate recovery, chemical tracers can be used to ,calculate, the amount of frac ,fluid, and hydrocarbon production being communicated between wells. Unique tracers tag the individual stages of a child well and identify which are communicating with the parent well.

One of the significant issues associated with fracking in shale is that massive amount ,of fracturing fluid, (~5–50%) is retained in the formation after the fracking process [10,11]. For example, Ge [9] and Penny et al. [12] reported that only around 5% of the water is recovered the ,fracturing, processes in shale while Nicot et al. [13] found less than 20%.
