POROSITY AND PERMEABILITY MEASUREMENT OF UNDERGROUND FORMATIONS CONTAINING CRUDE OIL, USING EPR RESPONSE DATA

摘要

A method and apparatus (100) for detecting and measuring the amount of crude oil in underground rock formations. EPR measurements are used to calculate t he amount of crude oil, and may be calibrated to determine the particular type of crude oil. These measurements may be used in conjunction with NMR measurements, to provide accurate estimations of pore size and permeability.
