Conductivity derived porosity from RTBR (CDPT) |
This is the name of a log measured along a well bore (a well-log). The acronym CDPT is a unique identifier to recognize this particular log and can be encountered in your log evaluation software or your corporate datastores. Conductivity derived porosity from RTBR is the full name for this log. This log is not often acquired after (or during) drilling a well. This log helps to evaluate 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 log therefore displays units of the volume fraction. This can be explained as being 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 from this log can be used to investigate the porosity of the formation. Similar logs are listed below:
