ABSTRACT:
Methods and apparatus are provided for making improved pulsed neutron derived measurements of the carbon: oxygen ratio in subsurface earth formations. Plural radiation measurements are made as a function of time from the initiation of the neutron pulse to distinguish inelastic and thermal neutron interactions. These measurements are also within their respective time functions, energy dependent. The time and energy dependent radiation measurements are then combined in several different manners to provide an improved carbon: oxygen ratio measurement and multiple porosity and formation lithology indication measurements.
