... devices that produce high energy neutrons without the use of traditional chemical sources. Measurements available for the first time from a commercial PNG-based LWD service include neutron-gamma density (NGD) for bulk density and density porosity. Extensive testing for neutron-gamma density was conducted...

.... Deploying logging tools with chemical sources poses Health, Safety and Environment (HS&E) risks requiring specific procedures throughout the entire process of planning, logistics and execution of well construction. Obtaining similar, identically equal or better formation bulk density and neutron...
