Geotechnical Drilling Casselberry How Fractured Ground Affects Drilling

When it comes to drilling, it is not so cut and dry and you might think when boring thru the Earth. The kind of ground conditions a driller encounters will play a huge role in how the project goes and the types of decisions that will need to made by a company performing geotechnical drilling. Casselberry residents need to understand that ground conditions include more than just the hardness of the ground and choosing the right matrix for a particular hardness. While it is important, other decisions will need to be made as well. Fractured ground is common for drilling companies and they should consider the following before committing to a drilling endeavor.

Fractured Ground Has The Potential For Water Loss

Ground that has a fault or void present can cause poor water circulation or loss of water return leading to poor drilling bit performance. The returning flow of water from the bore has a cushioning effect on the drill rods, making it easier and more effective to continue geotechnical drilling. Casselberry drillers can encounter fractured ground at some point in their project, which causes the driller to lose return water. This means that the upper part of the drill string may not experience this cushioning effect and vibration may be increased at that point, making it hard to control and hard to go deeper with drilling.

Hitting a Void

When drilling in highly fractured or broken ground, drilling companies run a higher risk of hitting a void or large fracture and having your drill water escape through that fault. Drill operators find out themselves that a dry hole and dry bores are a pain to deal with. They end up drilling blind because they are not getting any water return and they will not get an indication that the core is blocking. In this circumstance of geotechnical drilling, Casselberry drill operators will have no water return, which greatly increases the drilling cycle time and, if they are in an area with limited water resources,they will not be able to recycle your water.
