  "id": "MLC-T-OAG-001513",
  "term": "Fluid-loss control",
  "field": "Oil and gas",
  "definition": "The management of filtrate invasion from a drilling fluid, cement slurry, or completion fluid into a permeable formation. This is achieved by forming a low-permeability filter cake on the wellbore wall through the use of specialized additives like starches, polymers, or gilsonite. The standard laboratory procedure for evaluating fluid-loss control is the American Petroleum Institute (API) filter press test, which measures the volume of filtrate collected over a 30-minute period.",
