  "id": "MLC-T-OAG-001616",
  "term": "Gas coning",
  "field": "Oil and gas",
  "definition": "The upward movement of free gas into a producing oil wellbore, forming a cone shape in the reservoir. This occurs when the pressure drawdown during oil production is too high, causing the gas-oil contact to rise unevenly. Gas coning reduces oil production efficiency and increases the gas-oil ratio, often necessitating production rate adjustments.",
