Neutronenlogs
Neutronenlogs, also known as neutron logs, are a type of well logging technique used in the oil and gas industry to measure the neutron flux in a borehole. This measurement is crucial for determining the porosity of the rock formations surrounding the well. Neutron logs work on the principle that neutrons emitted from a radioactive source will slow down and lose energy as they collide with hydrogen atoms in the rock. The slower neutrons are then detected by a neutron detector, and the count rate is used to calculate the porosity of the formation.
There are two main types of neutron logs: the thermal neutron log and the fast neutron log.
Neutron logs are particularly useful in formations with high clay content, where other logging techniques like
The data from neutron logs are typically presented as a track on a well log plot, showing
