ABSTRACT:
An exploration method is disclosed for mapping subsurface migration of crude petroleum by measuring electron spin resonance signals from materials within samples of the subsurface formations and identifying the samples that contain petroleum crude by detecting enhancement and/or suppression of the electron resonance signals due to the addition of a chemical material. Electron spin resonance signals from crude oil are enhanced by the presence of iodine and suppressed by the presence of ferric chloride.
