  "term": "Grain density",
  "field": "Oil and gas",
  "definition": "The density of the solid mineral material that makes up a rock, excluding any pore space. It is a fundamental property used in petrophysical calculations, particularly for determining porosity from bulk density measurements. For sandstone, the grain density is typically around 2.65 g/cm3, while for limestone it is about 2.71 g/cm3.",
