  "id": "MLC-T-OAG-000427",
  "term": "Bouguer anomaly",
  "field": "Oil and gas",
  "definition": "The difference between the observed gravity value at a station and the theoretical gravity value, after corrections for elevation, topography, and the gravitational effect of the rock mass between the station and a reference datum. This anomaly reflects lateral density variations in the subsurface, which can indicate geological structures like salt domes or sedimentary basins. It is expressed in milligals (mGal).",
