Envirnonmental concerns about “fracking” Hydraulic Fracture Natural Gas Drilling

Quoting from the Register Herald Article…

Environmental concerns related to fracking include concerns about groundwater quality, surface contamination and possible induced seismic activity. Further, the long-term effects of fracking have not been fully studied.

Natural fractures occurring in the shale are typically vertical. By drilling horizontally, the wells are more likely to intersect natural fracture patterns to take advantage of fracture networks in the shale, increasing the volume of gas extracted from a single site.
