Air Rotary w/Casing Hammer

This type of drilling is completed using an impact hammer to drive the steel casing into the formation. This construction method is employed in unconsolidated formations (silt, sand, gravel, and small boulder). We drill ahead of the casing by 1-3 feet and then advance the casing with the hammer. This gives us the ability to measure flow rates, total dynamic head (TDH), iron, and pH levels of the various layers encountered. We are also able to separate these water-bearing zones. The separation becomes important when an artesian well is desired in certain areas. Different layers exhibit different hydrostatic pressures, and isolating them is crucial for clients seeking this outcome. Typically, the deeper we drill into the formation, the higher the hydrostatic pressure in areas with enough pressure to naturally push water out the top of the well.
