Grain density measurement
WebJun 24, 2015 · A density-logging tool sends gamma rays into a formation and detects those that are scattered back. Typical logging sondes use a Cesium-137 source, which emits gamma rays of 0.66MeV. At this high energy level, Compton scattering dominates. The average electron density in the volume of formation probed by the tool controls the … Webparameters include porosity (Φ), grain density (p s; or grain specific gravity, which is defined as the ratio of the mass of the mineral grains to the mass of an equal volume of fresh water; in the cgs system, it is numerically equal to grain density), water content (we = % dry weight; w c * = % wet weight), wet-bulk density (çQ, and density of
