Density Porosity from ROBB (DPHB) |
This is a well log used in the oil and gas industry. You could find this abbreviation DPHB in your log evaluation software or any (ASCII) log files provided by the logging company. The abreviatin stands for 'Density Porosity from ROBB'. Usage of this log is not high and encountering it is a rare occasion. Use this log to investigate the porosity derived from a formation density measurement. At a higher level, this can be seen as a measure of the apparent porosity. This can be explained as being the initial estimate of porosity, normally from logs, not corrected for the (often large) effects of clays, gas, etc. Such estimates should only be used for qualitative interpretation of clean, gas-free intervals. In general this is a measurement of the volume fraction. This is a measure of the ratio of the volumes occupied by two components, or by one component to the total volume of the system.This log usually has the unit 'Porosity'. This is the pore volume per unit gross volume. Porosity is determined from measurements on cores or interpreted from logs. Data for this log is produced by a tool that uses a density logging technique and can be used to investigate the porosity of the formation. Similar logs are listed below:
