Porosity Logs - UiO
www.uio.no– High energy gamma rays (Compton scattering) determine bulk density and therefore porosity – Low energy gamma rays (due to photoelectric effect) are used to determine formation lithology • Low energy gamma rays are related to the lithology and show little dependence on porosity and fluid type • Symbol for density: ρ(rho) High energy
Compton Scattering - High Energy Physics
pages.hep.wisc.eduThe Compton scattering of the 662 keV gamma rays from the decay of Cs137 is measured using a Sodium Iodide detector. The scattered energy and the differential cross section are both measured as a function of scattering angle, and the results are compared to the full relativistic quantum theory of radiation.
