..., then, in the presence of a very strong magnetic field, they will resonate at a specific microwave frequency. By exposing the well fluid to exactly that combination of magnetic and RF fields, the amplitude of the resonance is proportional to the number of asphaltene molecules. Unlike some optical and infra-red...
