TRANSPORT STORAGE AND DISPOSAL OF FRACKING WASTE

Because federal regulations prohibit the discharge of shale gas wastewater ,directly, from a production site into surface waters, fracking well operators in the northeast generally have three options for managing their contaminated fracking wastewater: (1) having the water treated to remove the contaminants then ,discharged, into surface water; (2) recycling the water within their fracking …

Polymers in the ,flowback fluid can, be in different states of solution and have significantly different molecular weights from the polymers that were pumped downhole. In many cases, a breaking agent is used to reduce polymer viscosity, which promotes HF ,fluid, flow from the fracture and helps the proppant stay in place during ,flowback,.
