Thermal Neutron Porosity, Enhanced Vertical Resolution (NTNP)

This is the name of a log measured along a well bore (a well-log). The acronym NTNP is a unique identifier to recognize this particular log and can be encountered in your log evaluation software or your corporate datastores. The abreviatin stands for 'Thermal Neutron Porosity, Enhanced Vertical Resolution'. This log is often used in the industry.

This log can be used to evaluate the porosity as measured with a thermal neutron logging device.

Simply said, this is a log that describes the porosity as measured with an neutron logging device. In general this log therefore displays units 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 neutron logging technique and can be used to investigate the porosity of the formation. Similar logs are listed below:
