METHODS OF DETERMINING CEMENTATION EXPONENT AND SATURATION EXPONENT IN POROUS MEDIA FROM DIELECTRIC DISPERSION DATA

摘要

Methods are provided for determining values of a pore cementation exponent m and/or a saturation exponent n for locations in a formation having similar petrophysical properties. Formation porosity, formation water saturation, and an apparent cementation exponent m_n are obtained for the locations and their values are utilized to find the exponents. In one embodiment, the apparent cementation exponent and the formation water saturation are obtained from a dielectric logging tool.
