Hydraulic fracturing - Wikipedia

The fracturing fluid varies depending on fracturing type desired, and the conditions of specific wells being fractured, and water characteristics. The fluid can be gel, foam, or slickwater-based. Fluid choices are tradeoffs: more viscous fluids, such as gels, are better at keeping proppant in suspension; while less-viscous and lower-friction fluids, such as slickwater, allow fluid to be pumped at higher rates, to create …

“Flowback fluid” is the waste that returns up the well bore during the initial stages of fracturing and production. The volume of flowback fluid is high in the first few weeks and months of operation, when as much as 40% of the initial fracture fluid volume can make its way back up the well bore. “Produced fluid” is the wastewater generated once the well begins producing hydrocarbons in volume.
