ABSTRACT:
The flow path of petroleum in underground reservoirs is monitored by injecting a stable free radical, or spin label, into the reservoir as a tracer which becomes detectable in a sample taken from a producing well. Detection of the spin label is by electron spin resonance (ESR) spectroscopy. Spin label tracers are, on the average, detectable at dilutions 1 million times lower than is possible with standard chemical tracing methods.
