Frequently Asked Questions
How do you know when you hit water?
We have a huge air compressor on the rig that blows air down the drill stem. The air comes back up the hole with enough force to move all cuttings up and out of the hole. If the well is producing water, the water will come too. Most of the time, we are actually pumping water into the air stream already, and we are really looking for an increase in the water. If we think we have hit water, we can turn off our water injection pump and check the flow of water with the air compressor alone.
How do you know how much water the well will produce?
There is no definite answer to this question. We are estimating the flow based on what we see flowing from the well. Sometimes, the air pressure in the well can “hold back” on the flow, causing us to underestimate the production capacity. To overcome this, we can release the air pressure for a few minutes, and then reapply it after the well has built up a large volume. We then would see the volume of water that the well produced after several minutes. Then with simple math, we can calculate the production capacity.
How do you know how deep to drill?
We are not only looking for water. We are mainly looking for the rock that produces water. The depth of each layer of rock depends greatly on the location and elevation of the drill site. The formations are relatively flat below the surface. However, they may not be level. We use a gps to tell us the elevation of your drill site and we survey the area wells that we have drilled and compare their elevations. From this, we can estimate the depth that your well will need to be. However, we have found out on many occasions, that when God laid the foundations of the earth, He followed no rules. It is not uncommon to see formations rise or fall several hundred feet in a mile. For instance, we drill in one subdivision where the depth to the lower trinity is 760’ on one side of the road, and 840’ on the other. We can never be sure about the depth of your well until we actually drill.
