Litho density tool
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. Webcompensated formation density logs, an example of which is Schlumberger’s FDC (formation density compensated) tool. Compensated formation density tools have one focussed (collimated) radiation source, one short spacing detector at 7 inches from the source, and one long spacing detector 16 inches from the source (Fig. 13.1).

WebThe Litho-Density Tool, LDT, provides an improved measurement of the formation density and a new measurement of lithology. Field tests of LDT proved that the tool could be run alone in a wide range of formations to provide porosity values comparable to those obtained by running a density log combined with a neutron log. WebIn geology, bulk density is a function of the density of the minerals forming a rock (i.e. matrix) and the fluid enclosed in the pore spaces. This is one of three well logging tools …
WebThe litho-density tool combines a borehole- corrected bulk density measurement with a photoelectric lithology log (Pe). A radioactive source and detectors are mounted in an articulated skid maintained in contact with the borehole wall by a powered backup arm. The arm also doubles as a caliper measurement.
