INTERPRETATION OF WIDE-BAND RESISTIVITY DATA Russian patent published in 2012 - IPC G01V3/30

Abstract RU 2452982 C2

FIELD: physics.

SUBSTANCE: claim describes resistivity measurements taken at multiple frequencies. An asymptotic high-frequency limit is determined and electrical efficiency is calculated in form of a ratio of the high-frequency limit of resistivity and low-frequency resistivity. Based on the electrical efficiency, petrophysical parameters of the rock, such as porosity and water saturation, can be calculated.

EFFECT: high accuracy of the obtained probing data.
