Zusammenfassung:	Methods of treating flowback water from a subterranean formation penetrated by a well bore are provided, comprising: (a) providing remediated flowback water having a ferrous iron (Fe+2) ion concentration of less than about 100 milligrams of ferrous iron ion per liter of flowback water, a barium ion (Ba+2) concentration of less than about 500 milligrams of barium ion per liter of flowback water, and a calcium ion (Ca+) concentration of at least about 1,000 milligrams of calcium ion per liter of remediated flowback water; and (b) treating the flowback water with: (i) at least one friction reducing agent; and (ii) at least one scale formation inhibiting agent and/or at least one iron precipitation control agent to provide treated flowback water which can be reused as fracturing fluid in a well drilling operation.
