Differential pressure sticking

  "id": "MLC-T-OAG-001071",
  "term": "Differential pressure sticking",
  "field": "Oil and gas",
  "definition": "A condition where the drill string becomes stuck against the wellbore wall due to a pressure imbalance. This occurs when the hydrostatic pressure of the drilling fluid in the wellbore exceeds the formation pore pressure, pressing a section of the drill pipe against a permeable formation. The pressure differential creates a force that holds the pipe against the filter cake, preventing its movement.",
