Certain wellbore fluid stimulation treatments may be monitored by a system including instrumented manifolds which may be connected between a base fluid source and a blending unit and between the blending unit and fluid injection pumps, respectively for measuring flow rates of the base fluid, the fluid additives and the fluid composition formed by the base fluid and the fluid additives. Instruments are also provided for measuring fluid temperature, pH, viscosity and flow behavior indexes (n′, K′) and fluid density. Quality control and determination of pressure losses in the wellbore together with modeling of stimulation treatments may be carried out by the continuous monitoring of parameters with the base fluid manifold and the mixed composition manifold.

A method for monitoring the quality of a fluid composition for injection into a wellbore for performing a formation treatment process, said method comprising the steps of: providing at least a first instrument manifold adapted to be interposed between a source of fluid and pump means for pumping said fluid to a wellbore, said first manifold including first and second manifold members interconnected by flow conduit means, said manifold members each including respective fluid inlet and outlet conduit connectors for connecting said first manifold to a source of fluid and to conduit means for conducting fluid from said first manifold, and a sample flow conduit connected to said first manifold for receiving a sample of fluid flow through said first manifold, said sample flow conduit including viscometer means interposed therein; conducting liquid through said sample flow conduit at selected flow rates; measuring at least the apparent viscosity of said fluid at respective selected shear rates of said fluid; and determining at least one of the consistency index (K\) and the Power Law Index (n\) of said fluid prior to injection of said fluid into a wellbore.
