Molecular tracers and modified proppants for monitoring underground fluid flows

Patent ·
OSTI ID:1771744
The present invention relates to modified proppants and methods of using the modified proppants that use metal ligand tracers to characterize subterranean fluid flow. The metal and ligands are best chosen to be a strongly-coordinating, chelating ligand with a functional group for the chosen flow environment.
