Relative dielectric constant

  "id": "MLC-T-OAG-003093",
  "term": "Relative dielectric constant",
  "field": "Oil and gas",
  "definition": "A dimensionless quantity that describes the ability of a material to store electrical energy in an electric field, relative to the permittivity of a vacuum. In formation evaluation, it reflects the water saturation and porosity of reservoir rocks, as water has a significantly higher dielectric constant than oil or gas. This property is measured by dielectric logging tools operating at microwave frequencies.",
