  "term": "Zonal",
  "field": "Oil and gas",
  "definition": "Relating to or arranged in zones or layers with distinct characteristics. In reservoir characterization, zonal analysis involves dividing a formation into horizontal layers, each with its own average properties like porosity, water saturation, and permeability. Petrophysicists calculate these properties from well log data for each zone to build a layered reservoir model for simulation.",
