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

www.utoledo.eduIncoherent (Compton) scattering • It involves an interaction between a photon and an electron • It is almost independent of Z; decreases with increase in E • In each collision some energy is scattered and some transferred to an electron, the amount depending on the angle of emission of the scattered photon and the energy of the photon.

iitk.ac.in• the scattering factor f j quantifies the efficiency of X-ray scattering at any angle by the group of electrons in each atom – The scattering factor is equal to the number of electrons around the atom at 0° θ, the drops off as θ increases • N j is the fraction of every equivalent position that is occupied by atom j
