Abstract

A well logging system and method for determining the water saturation of an earth formation and the resistivity of the water using complex dielectric constant and formation porosity measurements. Electromagnetic energy is transmitted into the earth formation from a borehole at a frequency lying within the range of frequencies from 10 MHz to 200 MHz. Electromagnetic energies are received at two locations in the borehole. A complex dielectric constant is derived from the received electromagnetic energies. The water resistivity and the water saturation of the earth formation is derived in accordance with the porosity of the earth formation and with the real and imaginary parts of the derived complex dielectric constant.
