A location where a well is drilled for extracting oil, gas, or water from the ground.
The engineers set up the equipment at the wellsite to begin drilling.
Wellsite → It is formed from "well" (from Old English *wella*, meaning a spring or source of water) and "site" (from Latin *situs*, meaning a place or location). The word "wellsite" refers to a specific location where a well is situated.
Think of a 'spring' or 'source of water' ('well') and a 'place' ('site') — together they describe a location where water is found.
