Abstract:
The present disclosure describes methods and systems for detecting a tracer in a hydrocarbon reservoir. One method includes injecting a tracer at a first location in a reservoir, wherein the tracer mixes with subsurface fluid in the reservoir; collecting fluid samples at a second location in the reservoir; mixing a magnetic surface-enhanced Raman scattering (SERS) particle with the fluid samples; applying a magnetic field to the mixed fluid samples; and analyzing the fluid samples to detect a presence of the tracer in the fluid samples.

Claim (Index 16):
A magnetic surface-enhanced Raman scattering (SERS) particle, comprising:\n a non-magnetic particle shell that is decorated with metallic particles, wherein the metallic particles comprise at least one of an Ag or Au particle; and a magnetic core particle that is incorporated into the non-magnetic particle shell, wherein the magnetic core particle comprises at least one of an Fe 3 O 4 , \u03b3-Fe 2 O 3 , MnFe 2 O 4 , or CoFe 2 O 4  particle.
