6. Hydraulic Fracturing Process
Planning Phase: A team of engineers design a plan by incorporating all the aspects of the plant(infrastructure,well pad sites and wells)
Execution Phase: To construct all the components(well pad sites,wells,etc),while keeping safety in mind. Then create an environmentally friendly space for water storage.
Performance Phase: The hydraulic fracturing process is started to release the natural gas from the shale by using multiple water resources.
Operational Phase: To extract the natural gas from the well and transporting it. Produced water used for fracking is disposed and treated in a nearby site.
