Nuclear well logging with neutron source and separate spaced radiation detectors to determine silicon/oxygen ratio

Creators

Description

Earth formations surrounding a well borehole are bombarded with high energy neutrons which react with chemical elements in the formation components, giving rise to gamma radiation. The gamma radiation is detected by two separate, spaced detectors from which well logs are obtained indicating a ratio of the relative presence of silicon to oxygen in the formations
