Volumetric Photoelectric Factor, Bottom (UB)
This is a well log used in the oil and gas industry. You could find this abbreviation UB in your log evaluation software or any (ASCII) log files provided by the logging company. The abreviatin stands for 'Volumetric Photoelectric Factor, Bottom'. This log is not often acquired after (or during) drilling a well. This log can be used to evaluate the lithology indicator computed from bulk density and Photoelectric Factor; often expressed in an approximation unit barns/cc.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 volumetric photoelectric factor of the formation. Similar logs are listed below:
