  "term": "Rod string",
  "field": "Oil and gas",
  "definition": "A series of interconnected sucker rods extending from the surface pumping unit down to the subsurface pump in an artificially lifted oil well.

The design of a rod string, including rod sizes and materials, is selected based on well depth, fluid properties, and production rates.",
