  "id": "MLC-T-OAG-001987",
  "term": "Injection mandrel",
  "field": "Oil and gas",
  "definition": "A side-pocket mandrel installed in the tubing string to hold a retrievable injection valve, either a gas-lift valve that meters annulus gas into the tubing or a chemical-injection valve fed through a control line or the annulus. The valve sits in an offset pocket, so wireline can run and pull it without pulling the tubing. Pockets commonly accept valves of 1 inch or 1.5 inch outside diameter.",
