  "term": "Tracer-loss measurement",
  "field": "Oil and gas",
  "definition": "A technique used in production logging to identify zones where injected fluids are being lost from the wellbore into the formation. A chemical or radioactive tracer is added to the injection fluid, and its concentration is monitored as it flows down the well. A decrease in tracer concentration indicates fluid loss into a permeable zone, often expressed as a percentage of the injected volume.",
