In water well drilling rig operations, soil surveys guide soft soil bit selection critically.
-
Scan with radar and test samples first.
Map clay/loam depth,
thickness,
and water content changes.
-
Check clay’s plasticity index—higher means stickier soil. Choose bits with larger opening angles.
-
Note special layers: Prepare collapse-proof bits for muddy clay; enhance cuttings removal for sandy loam.
Draw detailed geological maps from surveys. They guide tools, parameters, and mud mix for water well drilling rigs, avoiding inefficiency.
