Hydrofracturing of Water Wells
When a well is drilled in homogeneous and low porosity rock it sometimes turns out to be dry or a low producer, there is no or very little water to be found. However, this doesn’t mean that the rock is not water bearing.
Water in hard rock is generally located in cracks and fractures originating from the natural geological processes. These cracks are usually a very good water source. The problem is being lucky enough to drill the actual well into suitable water bearing fracture zone.
The difference between a productive and a dry well can be just the width of a man’s hand. So, today Hydrofracturing has been introduced as an add on in Water Well Drilling industry.
The object being, rather than abandoning a semi dry expensively drilled water well, but to create a man made conductive fracture by pumping water under extreme pressures into the well under controlled and safe conditions, and subsequently increasing the effective well-bore radius.
