Tungsten Radiation Shielding in Logging-While-Drilling

The logging-while-drilling tool provides real-time apparent neutron porosity, formation bulk density and photoelectric factor data to characterize formation porosity and lithology while drilling. Due to its high density, excellent absorption behaviour against radiation and environmental friendly characteristics, tungsten alloy can be widely used to produce tungsten radiation shield in density detector of logging-while-drilling.

The radioactive sources are safely contained in the drill collar and are connected to each other by a tungsten radiation shielding that allows fishing by wire line through the drill pipe.These nuclear measurements are borehole compensated for improved accuracy. 360-degree images of density and porosity result from the rotation of the tungsten density detector.
