Abstract

The invention is for a method of forming and delivering a treatment fluid into a wellbore. In one aspect, a method is provided for pumping a first fluid having a relatively high concentration of a particulate suspended therein and pumping a second fluid having either none of the particulate or a relatively low concentration of the particulate suspended therein, and then merging at least the first and second fluids to form a treatment fluid having a merged concentration of the particulate. According to this aspect, the first fluid has a relatively high concentration of a hydratable additive and the second fluid has either none or a relatively low concentration of the hydratable additive.
