Porosity and permeability measurement of underground formations containing crude oil, using epr response data

Abstract

Method and detector (100) for quantitatively measuring and measuring the amount of crude oil in underground rock formations. Parametric Electron Resonance (EPR) measurements - used to find the amount of crude oil, and the measurements can be calibrated to determine the amount of a particular type of such crude oil. The measurements can be used in conjunction with more conventional nuclear magnetic resonance (NMR) measurements to obtain accurate estimates of the formation's pore size and permeability.
