Gravity-stable displacement

  "id": "MLC-T-OAG-001744",
  "term": "Gravity-stable displacement",
  "field": "Oil and gas",
  "definition": "A fluid displacement process in a reservoir where the injected fluid is denser than the displaced fluid, or vice versa, leading to a stable front that minimizes fingering and maximizes sweep efficiency. This condition is achieved when a denser fluid displaces a lighter fluid downwards, or a lighter fluid displaces a denser fluid upwards. It is a desirable condition for enhanced oil recovery projects.",
