APC OFS’s Litho Density Tool is part of the Gallop Suite and provides accurate bulk density (RHOB) and photoelectric effect (PE) measurements for formation porosity evaluation, and lithology identification.

Lithology tools are extremely important as they provide a clear picture of the feasibility of a well, which allows the user to adjust and maximize production accordingly. Dual detectors allow mud cake corrections to be applied, and a caliper measurement is also provided.
