sand lifting

1. n. [Well Workover and Intervention]
Another term for sand cleanout, the process of removing sand or similar fill from a wellbore. Many wells produce sand that may accumulate and restrict production if not removed from the wellbore by the production fluid. Coiled tubing and snubbing units are routinely used for sand-cleanout operations, enabling the well condition to be treated without removing the completion equipment or even killing the well.
Synonyms: sand cleanout
