METHOD FOR DETERMINATION OF REMAINDER OIL SATURATION OF BEDS Russian patent published in 2005 - IPC

Abstract RU 2248444 C2

FIELD: geophysics.

SUBSTANCE: method includes feeding 5 portions of radon indicator in volume, exceeding volume of porous space of examined beds for depth of research zone in 40-80 times. Feeding of radon indicator is performed until receiving non-changing indications of intensiveness of gamma-radiation in all beds, i.e. until occurrence of balanced state of radon concentration in bed fluids. Value of remainder oil saturation coefficient of beds is determined from given mathematical expression.

EFFECT: lower costs, simplified operations, higher sensitivity, higher trustworthiness.
