Stage 5 lasts for 980 years (i.e., to 1000 years from the injection of fracturing fluid). The well is shut‐in so no fluid leaves or enters the domain via the well nodes, and the fracturing fluid plume is allowed to migrate. The five stages of simulation are summarized in Table 3.

TRANSPORT STORAGE AND DISPOSAL OF FRACKING WASTE

Hydraulic fracturing is a technique designed to improve oil and gas production. It involves injecting large volumes of fluids and proppants (small spheroids of solid material) at high pressure into a well to create fractures in the source rock formation and carry the proppants into the fractures to hold them open when production begins.

The reuse and recycling of ,flowback fluid, is a newer and more expensive method, yet is gaining in popularity and use among the fracking industry. To be reused or recycled, the wastewater must be treated initially and then combined with ,water, to balance out the high salt concentrations (Easton 2015).
