Well Logging: Gamma Ray Log 2: The Gamma Ray Spectral Log measures the concentration of the three radioactive elements, potassium, thorium, and uranium that make up nearly the total gamma radiation encountered in rock formations. In the right hand tracks, the thorium and uranium concentrations are presented in packs per minute and the potassium concentration in percent. In the left hand track, the total gamma ray activity is displayed scaled in API units.
Ratios of the three elemental concentrations can be used as an indicator of formation properties. The thorium uranium ratio for example, varies with the environment of deposition. It is highest for sediments deposited in continental oxidizing environments and lowest for marine reducing environments. High uranium potassium ratios and shale indicate potential source rock.
The thorium potassium ratio has proved useful in typing clays. The ratio increases from glauconite then to illite to mixed layer clays to kaolinite chloride. The poster, Emmanuel Kofi Sakyiamah, is an experienced Petroleum Industry (Oil & Gas Crane Lifter/Rigger, HSSEQ, Materials Coordinator Professional, etc ) who has worked on several oil and gas exploration and production projects in Africa with GNPC, LUKOIL, NARANS ENERGY, ENI, SPRINGFIELD E&P, etc. You can reach E. Kofi Sakyiamah on +233 245 170 917 or +233 050 200 80 89 to engage him for his professional services with integrit; E. Kofi Sakyiamah is very prepared to work anywhere in the world.
