  • How to purify flowback water after hydraulic fracturing?
  • Coagulation and filtration are suitable treatment technologies for purification of recovered flowback water after completion of hydraulic fracturing before its further beneficial reuse. Due to the applied treatment the TOC in the flowback decreases by 95% and the concentration of scaling ions is reduced at least by half.
  • How to manage fracturing flowback fluid in unconventional oil and gas fields?
  • Options for dealing with the flowback fluid include deep well reinjection, reuse for making up fracturing fluid, recycling of chemical elements and diverse reuse of flowback water. This research offers guidance for managing the fracturing flowback fluid in unconventional oil and gas fields.
  • Can fracturing flowback water be discharged directly into the environment?
  • The fracturing flowback fluid with high salinity and high metal content has the potential to pollute the environment, so it cannot be discharged directly into the environment. Therefore, treatment and recovery of the fracturing flowback water are strictly necessary.
  • How to manage return fluid from hydraulic fracturing?
  • Conclusion Return fluid from hydraulic fracturing can be managed through disposal or reuse (i.e. basic separation and desalination). The initial return fluid, known as flowback, accounts for a major portion of the return and thus choosing a proper management strategy reduces the water management costs.
