  "term": "Sand lifting",
  "field": "Oil and gas",
  "definition": "The process of using fluid circulation to remove sand or other solid particles from the bottom of a wellbore. A high-velocity fluid, often nitrogen or a specialized liquid, is pumped down a tubing string to agitate the solids and carry them in suspension up the annulus to the surface. This technique is a common cleanout method for wells that have experienced sand production from the reservoir or have fill remaining from a hydraulic fracturing treatment.",
