Water well drilling in alluvial riverbed formation (sand, gravel, rocks and boulders) with a 18 imch pilot and 22 inch hole opener on a TH-60 drill rig and a mud puppy screen.
We also drilled and seta 24 inch steel pipe 40 ft deep as a conductor and slurried it inplace to hold the upper structure of the formation from collapsing in case it got undermined to prevent the drill rig from falling in the hole.
Drilled down to 230 ft deep for 12 inch casing.
