Hydrofracking for More Adequate Water Flow

When Delta Drilling drills a well, there is usually an adequate supply of water. However, certain locations may not yield an adequate flow of water for your wells. If this is the case, we can stimulate the well water with a technique called hydrofracking.

How Hydrofracking Works

First, we lower the tool called the packer into your well just below the casing pipe. The packer is about 5 inches in diameter and approximately 5 feet long. We then pump fluid into the packer which swells from 5 inches to the diameter of the bore hole—which is usually 6 inches for a domestic well—and we hold it in place by about 2000 pounds of pressure.

The packer has a 1 ¼ inch opening at its centre where 1 ¼ inch pipe(s) is attached. Water is injected through these pipes with 2000 to 4000 psi at a rate of 50 to 90 gallons per minute. The pressure washes the plugged fractures free of debris and allows water to fill the well at a better flow rate.

Success Rate of Hydrofracking

The success rate of hydrofracking depends on the bedrock surrounding your well. In general, formations of quartzite, greywacke, slate, or fine grain granite with high quartz concentrations yield little amounts of water when first drilled. Despite that fact, these formations are excellent candidates for hydrofracking with a success rate of about 95 to 100 percent.

Delta Drilling can take your well that produces almost no water and make it one that yields a gallon per minute. There are times that after hydrofracking, the water yield exceeds expectations with a flow rate of 10 gallons per minute or even greater. We’ve seen formations like sandstone, shale, and conglomerates show great results after hydrofracking.

One of the most difficult formations for hydrofracking is gypsum. Its soft nature makes drilling hard to conduct and often in this case a dug well is the better option.

Wells & Existing Homes

Iron, manganese, and other minerals can build up in your existing water fissure that supplies your well and limit the volume of water allowed to pass through. If you don’t think your well is producing the same rate of water as it has in the past, hydrofracking may be a way to stimulate the flow rate. Delta Drilling recommends, however, that your well be a minimum of 200 feet deep for adequate results.

Water pumps are not the only types of pumps we work with. Delta Drilling also offers heat pumps for geothermal heating. Contact us for additional information and request an estimate.
