What tool removes the fines after well surging?

Explanation:
When you surge a well, you loosen fines from the surrounding formation and need a way to physically remove those solids from the borehole. The bailer is designed for this purpose: it’s lowered into the well, fills with the loosened solids and liquid, and then pulled back up to surface, carrying the fines out. This makes it the most effective tool for removing fines after surging. A pump moves water out but isn’t a dedicated device for picking up and lifting solids from the borehole. A scoop or net isn’t practical for retrieving fine solids from deep, narrow well casings.
