First Claim
Patent Images
1. A method of tracking a fluid in a wellbore comprising:
- entraining a plurality of wireless identification (WID) tags in the fluid to form a slurry, wherein the WID tags comprise a plurality of peer-to-peer long wavelength (LW) tags in a visibility network;
injecting the slurry into the wellbore, whereby the LW tags enter a zone beyond range of a reader in the wellbore andlocating the LW tags in the beyond-range zone with at least one reader via the visibility network.

Abstract
A fluid can be tracked in a wellbore utilizing at least one WID tag, such as an LW tag or an RFID tag, entrained in the fluid. A WID tag reader can be disposed and/or displaced in the wellbore, for example, on a drill string or a casing string. A reader can be utilized to locate the at least one WID tag in the wellbore. A reader can be housed in a drill string sub. A fluid entrained with at least one WID tag can be utilized as a tracer fluid. A WID tag can be entrained in cement or a drilling or fracture fluid.
