15. THE NEUTRON LOG 15.1 Introduction
homepages.see.leeds.ac.uk15. THE NEUTRON LOG 15.1 Introduction The neutron log is sensitive mainly to the amount of hydrogen atoms in a formation. Its main use is in the determination of the porosity of a formation. The tool operates by bombarding the formation with high energy neutrons. These neutrons undergo scattering in the formation, losing energy

introduction to neutron scattering - NIST
www.ncnr.nist.govChapter 6 - INTRODUCTION TO NEUTRON SCATTERING Neutron scattering is the technique of choice for condensed matter investigations in general because thermal/cold neutrons are a non-invasive probe; they do not change the investigated sample since they do not deposit energy into it. 1. CHARACTERISTICS OF NEUTRON SCATTERING A few advantages of ...

Porosity Logs - UiO
www.uio.no• Since a neutron is slightly heavier thana proton, the element which closely approximates the mass of a neutron is hydrogen. In neutron-hydrogen collisions the average energy transfers to the hydrogen nucleus is about ½ that of the energy originally contained in the neutron. Whereas, if the scattering nucleus was oxygen
