Density logging is used to quantify the bulk density of the rock formations to calculate a matrix corrected total porosity (PHIt). PHIt is defined as the fraction of bulk rock volume that is not occupied by solid matter and which includes the clay bound water, free water and hydrocarbon volume occupying the pore space. To record this data in either open-hole or through-casing, a unique geometry is utilized that increases the depth of investigation of the density tool and improves the backscatter statistics. In a through-casing environment, this increase in backscatter statistics allows for the use of spectral deconvolution to correct for cased well borehole effects and calculate the formation bulk density. In open-hole, the tool is able to overcome the negative effects of thick mud cakes beyond ¾”. A PEF measurement is acquired in open-hole while a synthetic PE Matrix Component is calculated in cased-hole applications to determine lithology.
