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.

Web24 jun. 2015 · A density-logging tool sends gamma rays into a formation and detects those that are scattered back. Typical logging sondes use a Cesium-137 source, which emits gamma rays of 0.66MeV. At this high energy level, Compton scattering dominates. WebEUV lithography systems. Using EUV light, our NXE systems deliver high-resolution lithography and make mass production of the world’s most advanced microchips possible. Using a wavelength of just 13.5 nm (almost x-ray range), ASML’s extreme ultraviolet (EUV) lithography technology can do big things on a tiny scale.

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).
