Situ treatment analysis mixing system

A method for controlled delivery of a fluid for well bore operations comprising:

• a) providing a plurality of pressurized sources of a base fluid having respective flow rates, and providing at least one target predetermined characteristic value;
• b) blending at least two of the pressurized sources of base fluid creating a blended pressurized source of base fluid at an overall target blended flow rate;
• c) testing the blended pressurized source of base fluid to determine the blended source's at least one characteristic value;
• d) comparing the tested at least one characteristic data of the blended pressurized source of base fluid of step “b” to the target at least one target predetermined characteristic value to identify if they match;
• e) based on the comparison made in step “d” altering the flow rates of at least two of the plurality of pressurized sources of base fluid of step “a” while maintaining substantially the same target overall blended flow rate;
• and
• f) repeating steps “c” through “e” until the blended pressurized source of base fluid matches the at least one target predetermined characteristic value.
