A method for conducting density measurements in downhole environments corrects for high standoff, by adding a second correction term to the spine and rib method. This second term is a correction based on an apparent standoff estimated using the photo electric effect of the mud. This correction is term depends on the mud properties, both in terms of apparent standoff and correction and therefore requires property calibration for each well. The calibration can be done using the azimuthal information available with LWD tool when the tool is turning. At each depth in homogeneous formation, there can be a succession of density measurements with various tool standoff when the tool is not centered in the borehole. All this information is used to build up a standoff correction fitting perfectly the mud properties.
