Density Porosity, Sandstone (DPHS) |
This is a well log used in the oil and gas industry. The acronym DPHS is a unique identifier to recognize this particular log and can be encountered in your log evaluation software or your corporate datastores. The official name for this log is 'Density Porosity, Sandstone'. The business value of this log is often deamed high. Use this log to investigate the porosity derived from a formation density measurement, assuming that the rock matrix material is quartz. At a higher level, this can be seen as a measure of the apparent porosity. Better said, 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. 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:
