  • Exploration method using electron spin resonance signals from hydrocarbon crude
    Patent number: 4607014
    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.
    Type: Grant
    Filed: June 23, 1983
    Date of Patent: August 19, 1986
    Assignee: Chevron Research Company
    Inventors: Stephen W. Nicksic, George W. Starke
  • Well logging method using electron spin resonance signals from hydrocarbon crude
    Patent number: 4560663
    Abstract: A well logging method is disclosed for identifying the presence of crude petroleum within subsurface earth formations by detecting electron spin resonance signals along a well bore and identifying crude petroleum as the source of those signals by enhancing and/or suppressing the signal by the presence of a chemical. Electron spin resonance signals from crude oil are enhanced by the presence of iodine and suppressed by the presence of ferric chloride.
