Advantages of our Reverse Circulation Method includes:

1. The porosity and permeability of the formation near the borehole is relatively undisturbed compared to other methods.
2. Large-diameter holes can be drilled quickly and economically.
3. No casing is required during the drilling operation.
4. Well screens can be set easily as part of the casing installation.
5. Most geologic formations can be drilled, with the exception of igneous and metamorphic rocks.
6. Little opportunity exist for washouts in the velocity of the drilling fluid.
