    Abstract: The invention discloses method of treatment and reuse of oilfield produced water. The method comprises: providing an aqueous medium comprised at least in part of oilfield produced water; contacting the aqueous medium with a zirconium compound; whereby the fluid viscosity and/or fluid drag reduction ability of the combination of the aqueous medium and zirconium compound is improved compared to the aqueous medium alone; introducing the combination in to the well; and allowing the combination to contact the formation. In another embodiment, the aqueous medium is further contacted by a friction-reduction additive. Still in another embodiment, the aqueous medium is further contacted by a gelling additive. Still in another embodiment, the fluid is energized with a gas.
