Method for blending of concentrations for dilution on the fly

1. A process for preparing a diluted treatment fluid for introduction to a wellbore, comprising:

(A) measuring a treatment fluid flow rate;

(B) blending the treatment fluid with a treatment substance to produce a concentrated treatment fluid;

(C) measuring a flow rate of the concentrated treatment fluid;

(D) determining a difference between the treatment fluid flow rate and the flow rate of the concentrated treatment fluid;

(E) comparing the difference to a target difference;

(F) adjusting the difference to be within a desired range of the target difference; and

(G) diluting the concentrated treatment fluid to provide the diluted treatment fluid.

2. The process of claim 1 , wherein the treatment fluid comprises water, diesel, mineral oil, gels, foam, acid, or any combinations thereof.

3. The process of claim 1 , wherein the treatment substance comprises a proppant, a polymer, a cement, or glass beads.

4. The process of claim 1 , wherein measuring the treatment fluid flow rate and the flow rate of the concentrated treatment fluid are accomplished by flow meters.

5. The process of claim 4 , wherein the flow meters are magnetic flow meters.

6. The process of claim 1 , wherein the blending is accomplished in a blender.

7. The process of claim 6 , wherein the treatment substance is a proppant, and wherein a sand screw assembly feeds the proppant to the blender.

8. The process of claim 1 , further comprising blending additives with the treatment substance and the treatment fluid.

9. The process of claim 1 , wherein adjusting the difference comprises adjusting feed of the treatment substance to the blending, adjusting the treatment fluid flow rate to the blending, or any combination thereof.

10. The process of claim 1 , wherein the desired range is about equal to the target difference.

11. The process of claim 1 , wherein the difference corresponds to a volume of the treatment substance added to the blending.

12. The process of claim 1 , wherein diluting is accomplished in a blender.

13. The process of claim 1 , wherein diluting is accomplished in a dilution mix section, wherein the dilution mix section comprises a pipe section.

14. The process of claim 1 , wherein the blending is accomplished in a concentration blender, and wherein the diluting is accomplished in a dilution blender, and further wherein the concentrated treatment fluid is fed from the concentration blender to the dilution blender.

15. The process of claim 14 , wherein the concentrated treatment fluid is fed to a storage unit from the concentration blender prior to being fed to the dilution blender.

16. The process of claim 1 , wherein the blending is accomplished in a concentration blender, and wherein the concentrated treatment fluid is fed from the concentration blender to a storage unit for storage, and further wherein the concentrated treatment fluid is fed from the storage unit to the concentration blender for dilution.

17. The process of claim 1 , wherein the concentrated treatment fluid is diluted by a dilution fluid comprising the same fluid as the treatment fluid.

18. The process of claim 1 , wherein the process is controlled by a process controller.

19. The process of claim 18 , further comprising providing a specific gravity of the treatment substance to the process controller, providing the target difference to the process controller, and providing a target concentration of the treatment substance in the diluted treatment fluid.

20. The process of claim 1 , wherein the target difference comprises the treatment fluid flow rate subtracted from the flow rate of the concentrated treatment fluid or a ratio of the treatment fluid flow rate to the flow rate of the concentrated treatment fluid.
