| | Abstract | | Nuclear technique has been utilized for long time in logging field: it has been however mainly for measurement of the porosity of gamma-ray or neutron. Neutron induced gamma-ray analysis can be very strong tool for in-situ geophysical measurement and can be lead to identification of rock type under the environment where sample return is impossible such as sea sediment and deep well. In this presentation, we will discuss about the application of neutron gamma-ray analysis to exploration geophysics. |
