WebThe accuracy of the density measurement of the litho-density tool is approximately 0.01 to 0.02 g/cm3, whereas that of the formation density tool is approximately 0.02 to 0.03 g/cm3. The density measurement has a vertical bed resolution of 50 to 60 cm, which is slightly better than the formation density tool. http://geologging.ir/borehole-probe/litho-density/#:~:text=The%20litho-density%20tool%20combines%20a%20borehole-%20corrected%20bulk,The%20arm%20also%20doubles%20as%20a%20caliper%20measurement.

Web9 jul. 2024 · A new tool, the litho-density tool (LDT), has been used along with conventional logging tools in a mid-Jurassic sand/shale sequence. The LDT simultaneously measures P e (effective photoelectric cross-section) and ρ a (apparent bulk density). P e is a function of atomic number which in turn reflects lithology or mineral composition.
