Methods of using a higher-quality water with an unhydrated hydratable additive allowing the use of a lower-quality water as some of the water in the forming and delivering of a treatment fluid into a wellbore

摘要

The inventions are for methods of forming and delivering a treatment fluid into a wellbore. In one aspect, methods are provided of using higher-quality water for one portion of the water for a treatment fluid and lower-quality water for another portion of the water for a treatment fluid, and merging the two portions to form the treatment fluid after pumping the fluid portions toward the wellbore. This allows the use of lower-quality water for some of the water required for making up the treatment fluid.
