10 Questions
What does the formation density log measure?
The bulk density of the formation
What are the operational principles of formation density tools?
They bombard the formation with radiation and measure how much radiation returns to a sensor
What type of tools are formation density tools?
Induced radiation tools
What do gamma rays do when they enter the formation?
Undergo Compton scattering by interaction with the electrons in the atoms composing the formation
What is one of the learning outcomes related to density tools?
$LO1$: Understand the physical principles behind the operation of density tools.
What is the main use of Neutron Log in formation evaluation?
Determining the porosity of a formation
What happens to the emitted neutrons in Neutron Log when they hit the formation?
They undergo scattering, producing high energy gamma rays
What parameter does the neutron log sensor have high sensitivity to?
Hydrogen atoms
In neutron logging, what makes scattering more efficient when neutrons hit the formation?
Presence of hydrogen atoms
What are the three processes of interest in neutron logging?
