  "term": "Total organic carbon",
  "field": "Energy",
  "definition": "The concentration of organic material in source rocks represented as a percentage by weight of organic carbon. Approximately 0.5% total organic carbon by weight is the minimum for an effective source rock (meaning the source rock has enough organic carbon and thermal maturity to produce oil and natural gas), although 2% is the minimum for shale gas reservoirs. Values can exceed 10%.",
