Abstract:
A method of fracturing multiple productive zones of a subterranean formation penetrated by a wellbore is disclosed. The method comprises injecting a fracturing fluid into each of the multiple production zones at a pressure sufficient to enlarge or create fractures in the multiple productive zones, wherein the fracturing fluid comprises an upconverting nanoparticle that has a host material, a dopant, and a surface modification such that the upconverting nanoparticle is soluble or dispersible in water, a hydrocarbon oil, or a combination thereof; recovering a fluid from one or more of the multiple production zones; detecting the upconverting nanoparticle in the recovered fluid by exposing the recovered fluid to an excitation radiation having a monochromatic wavelength; and identifying the zone that produces the recovered fluid or monitoring an amount of water or oil in the produced fluid by measuring an optical property of the upconverting nanoparticle in the recovered fluid.

Claim (Index 12):
A method of determining water breakthrough in a production well associated with one or more injection wells, the method comprising:\n introducing into each of the one or more injection wells an aqueous fluid comprising an upconverting nanoparticle having a host material, a dopant, and a surface modification such that the upconverting nanoparticle is water soluble or water dispersible, the upconverting nanoparticle injected into each of the one or more injection wells emitting a different color of light when exposed to an excitation radiation having a monochromatic wavelength; flowing at least a portion of the fluid comprising the upconverting nanoparticle from the injection well into the production well; producing a production fluid from the production well; detecting the upconverting nanoparticle in the production fluid by exposing the production fluid to the excitation radiation having the monochromatic wavelength; and determining water breakthrough in the production well by qualitatively determining the presence or quantitatively measuring the amount of the upconverting nanoparticle in the production fluid, wherein the host material of the upconverting nanoparticle comprises NaYF 4 , NaGdF 4 , LiYF 4 , YF 3 , CaF 2 , Gd 2 O 3 , LaF 3 , Y 2 O 3 , ZrO 2 , Y 2 O 2 S, La 2 O 2 S, Y 2 BaZnO 5  or Gd 2 BaZnO 5 ; and the dopant comprises about 5 mol % to about 30 mol % of Yb 3+  and about 1 mol % to about 3 mol % of one or more of the following: Tm 3+ , Ho 3+ , or Er 3+ , each based on the total mole of the upconverting nanoparticle.
