How deep should a mud rotary drill rig be?

The history of old wells will indicate how far down the water table drops during dry seasons and will indicate how deep new wells must be. In general, the LS-100 mud rotary drill rig should only be used in areas where people are getting their water from hand dug water wells (less than 40 meters deep).

How much setback is needed for a directional drill rig?

For each horizontal well, a setback distance is needed.  Setback is the distance required from ground penetration to target depth; the typical ratio is 5 horizontal feet of set back for every foot of vertical penetration.  For example, if the target depth is 75’ bgs, the directional drill rig would begin drilling 375’ away from the target point.

How far away should a drilled well be drilled?

If existing dug wells will be disinfected (Section 15) and continue to be used, the new well should be drilled as far away as possible to ensure that both wells will produce sufficient amounts of drinking water without interfering with one another (drawing water from the same part of the aquifer).

What do you need to know before drilling a well?

This will help you determine where your well will be the most successful, as well as the locations where drilling the well will be cheaper. You can also employ a water surveyor to help you identify things like groundwater depth, potential yield, and suitability. What will you need to look for before you start drilling? 1) Your water requirements

How do you identify a high probability of drilling wells?

To identify areas where there is a high probability of successfully drilling wells, one must first prepare a site map (Section 2.8). Consideration must be given to each of the following seven factors which are critical in siting new water wells:

What is a directional drill rig setback?

Setback is the distance required from ground penetration to target depth; the typical ratio is 5 horizontal feet of set back for every foot of vertical penetration.  For example, if the target depth is 75’ bgs, the directional drill rig would begin drilling 375’ away from the target point.  See the illustration below.
