Abstract

Measurements made by a natural gamma ray tool are used to provide an elemental composition of an earth formation, Additional measurements made with a pulsed neutron toot with two or more gamma ray detectors are used to provide a mineralogical and/or elemental image of the formation. This may be used in reservoir navigation and in furthering the widerstanding of the geology of the prospect.
