摘要： An apparatus, method and computer-readable medium for estimating a bulk shale volume of an earth formation. In one aspect, measurements are obtained at a plurality of depths in a wellbore penetrating the earth formation and a first distribution is produced of the obtained measurements. A measurement is obtained at a selected depth in the wellbore and a second distribution is produced using the measurement at the selected depth and the measurements obtained at the plurality of depths. A cumulative distribution is produced cumulative of the first distribution and the second distribution. The bulk shale volume is estimated at the selected depth by comparing the cumulative distribution and the second distribution.
