Professional bits for all formations and drilling methods, classified by IADC (International Association of Drilling Contractors) codes for precise formation matching:
The most versatile and widely used bits in water well drilling, with three rotating cones that crush rock efficiently.
Fixed-cutter bits with polycrystalline diamond compact cutters that shear rock for exceptional penetration rates.
The IADC three-digit code system helps match bits to formation hardness:
Example: A 517 TCI tricone = medium formation tungsten-carbide bit with sealed journal bearings and gauge protection
Casing maintains the well opening, prevents collapse, and protects the water source from contamination:
Thermoplastic pipe that is lightweight, corrosion-proof, and cost-effective for domestic and irrigation wells.
Traditional high-strength casing for deep, unstable formations and municipal water supply wells.
Proper joint selection ensures well integrity and watertight seals:
Male threads on pipe ends screw into coupling sleeves. Quick and effective for smaller diameters (4-12"). NPT tapered threads or O-ring sealed buttress threads for PVC.
Butt-welded joints for large-diameter steel casing. Strong, permanent, smooth exterior profile. Often required for public supply wells.
Flared bell end receives plain spigot end, then lap-welded. Easier alignment, low exterior profile. Common in municipal construction.
Short sleeve welded around joint. Creates joints as strong as casing itself. Ideal for stainless steel screens joined to carbon steel casing.
Screen selection is critical - the slot size must retain formation or filter pack material while allowing maximum water flow:
| Aquifer Material | Typical Slot Size | Notes |
|---|---|---|
| Fine Sand | .010" - .015" | May require gravel pack for best results |
| Medium Sand | .020" - .030" | Most common residential applications |
| Coarse Sand | .030" - .040" | Natural development often sufficient |
| Gravel/Coarse Material | .040" - .060"+ | High capacity irrigation/municipal wells |
| With Gravel Pack | Based on pack D10 | Retain 90-100% of pack material |
A properly designed filter pack increases well yield, prevents sand pumping, and stabilizes the aquifer around the well:
Proper annular sealing prevents contamination and ensures code compliance:
Best Practice: Bentonite for lower annulus, cement cap for upper 10 feet near surface

Choose the right drilling method based on formation type, depth, diameter, and project requirements:
Most common method for modern water wells
Fast drilling in hard, dry rock formations
Historic method still valuable for special applications
Large-diameter municipal and high-capacity wells
| Residential (sand/clay): | Mud Rotary |
| Residential (bedrock): | Air Rotary / DTH Hammer |
| Irrigation (alluvial): | Mud Rotary |
| Municipal (large diameter): | Reverse Circulation |
| Remote/bouldery: | Cable Tool |
| Mixed formations: | Combination approach |
Many projects use multiple methods - e.g., mud rotary through overburden, then DTH hammer in rock
