8.2 Logging with Pulsed Neutron Beam
413
accumulated conrms that well logging systems based on electronically con-
trolled neutron generators and neutron measurement has huge potential for
the future development. e accumulated experience should be transformed
into new ideas in the future generation of the tool design. In general it can be
said that the future tool design should tend to two dierent directions:
1. To build simple, reliable, and, for the independent service companies,
aordable tool for saturation measurement in general and in low
salinity and low porosity environment in particular
2. To build complex tool that will utilize energy spectrum analysis of
natural gamma ray, inelastic gamma ray, gamma ray as result of ther-
