Abstract

1519978 Borehole logging EXXON PRODUCTION RESEARCH CO 16 Oct 1975 [3 March 1975] 36558/77 Divided out of 1519977 Heading G1N The partial water saturation Sw of a formation in a borehole is determined from the dielectric constant of the formation. The formula C t = F*-1 (CwSw + BQuS<SP>P</SP>w) is employed to calculate the water saturation Sw where C t is specific conductivity of the shaly sand formation being tested, F* is formation resistivity factor for shaly sand, Cw is specific conductivity of the aqueous saturant, p is shaliness exponent, n is desaturation exponent, B is equivalent conductance of clay exchange cations as a function of Cw at 25‹C and Qv is cation exchange capacity per unit pore volume. The values of C t , F* and Cw are obtained from routine well logging methods. The dielectric constant of the formation is measured by "deep" dielectric measurements using a logging tool including a pair of vertically spaced bow electrodes and the circuit described in Specification 1519977. The value of the conductivity parameter BQ V S<SP>p</SP>w is then obtained by comparing the measured dielectric with a correlation relating dielectric to the conductivity parameter. Methods of obtaining the correlation are described.
