Method for determining the presence of platinum in earth formations

Creators

Description

A spectral natural gamma radiation logging tool is calibrated with a material of known potassium content so that the natural gamma radiation measured by such logging tool is related to potassium concentration. The earth formations surrounding a borehole are logged with such logging tool to identify the presence of potassium. A specified concentration of potassium correlates inversely with a magnetic mineral content in the earth formation. The amount of magnetic mineral content is a measure of the presence of the non-magnetic mineral platinum in the earth formation
