High Resolution Porosity from Enhanced Density (HPHN) |
This is an acronym for a well log used in the oil and gas industry. The acronym HPHN is a unique identifier to recognize this particular log and can be encountered in your log evaluation software or your corporate datastores. The full name for this log used in the industry is 'High Resolution Porosity from Enhanced Density'. The usage of this log is well established. The values of this log represent the porosity derived from a formation density measurement. Furthermore, this can be explained by looking at the apparent porosity. This is a measure of 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. At a more general level these values are measures of the volume fraction. Better said, 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:
