Pulsed neutron well logging system
Description
The invention relates to pulsed neutron well logging for the direct location and distinction of oil sands from water sands, whereby capture gamma rays from the element hydrogen are detected along with the activation capture gamma rays from the element oxygen. As the hydrogen to oxygen ratio is substantially different for hydrocarbons than for water, a well log which is indicative of hydrocarbons in the pore spaces of earth formations surrounding the well borehole may be obtained
