Pulsed Neutron Logging Tool

PNNL

The tool has the following modifications by max operating temperature T max and upper value of borehole hydrostatic pressure Pmax :
  by temperature: 120°C,
  by pressure: 80 MPa.

Designed for measurements using pulsed neutron logging (2INNK or 2INGK) by thermal neutrons time spectra recording (2INNK) or gamma ray recording (2INGK) by two sondes with simultaneous recording of gamma-ray logs (GR) in 2INNK modification and casing collar locator (CCL), temperature inside the tool, tool head voltage.
