  "term": "Filtercake",
  "field": "Oil and gas",
  "definition": "A layer of solid particles deposited on a permeable rock face as the liquid phase of the drilling fluid is forced into the formation by pressure. A thin, low-permeability filtercake is desirable to limit fluid loss, stabilize the wellbore, and prevent formation damage. Its thickness and permeability are measured in a laboratory using a filter press test, with results reported in millimeters or 32nds of an inch.",
