Method for modifying electron spin resonance signals from hydrocarbon crude |
| abstract |
Method for enhancing electron spin resonance signals from crude petroleum by contacting the crude petroleum with a chemical which effects the population of free radical asphaltenes in the crude petroleum. The enhancement is in a positive sense when the chemical is a halogen and particularly iodine. The enhancement is in a negative sense (suppression) when the chemical is ferric chloride. |
