HRDD Standard Resolution Formation Photoelectric Factor (PEFZ)
This is a well log used in the oil and gas industry. You could find this abbreviation PEFZ in your log evaluation software or any (ASCII) log files provided by the logging company. The code stands for 'HRDD Standard Resolution Formation Photoelectric Factor'. The usage of this log is well established. The values of this log represent the photoelectric Factor of the filter cake (mudcake); often expressed in an approximation unit barns/electron.
Concluding, this is a measure of the probability that scattering due the Photoelectric Effect will occur; often expressed in an approximation unit barns/electron.This log in unitless. Either the log measurements can not be expressed with a unit (eg. a ratio) or the unit is unknown to us.
Data from this log can be used to investigate the photoelectric factor of the filter cake.
