2 3/4" In-Line Neutron Tool

Product Reference: 050-NU275-00BL



The In-line Neutron Tool is used to determine the hydrogen index of the formation which is related to formation porosity and fluid content.

This cased-hole tool uses a single, high temperature, ruggedized 1-inch x 8-inch He3 thermal neutron detector to measure the neutron cloud from a chemical neutron source. The source detector spacing is variable from 11-inch to 17-inch and can be optimized for well conditions and neutron source types. Detector spacing is easily changeable in the field.

The tool uses a bottom load 3 or 5 Ci AmBe neutron source. When combined with a Gamma Ray and Dual Receiver Cement Bond Log (CBL), the data is multiplexed with the Gamma Ray, Casing Collar Locator (CCL), and CBL data in a single pass in the well.

Data transmission to surface is achieved via multiple line driver, or by digital telemetry.
