Fracking is the process of
extracting natural grass from shale rock layers deep within the earth. Fracking
makes it possible to produce natural gas extraction in shale plays that were
once unreachable with conventional technologies. Recent advancements in
drilling technology have led to new man made hydraulic fractures in shale plays
that were once not available for exploration. In fact, three dimensional
imaging helps scientists determine the precise locations for drilling.
Horizontal drilling allows for
the injection of highly pressurized fracking fluids into the shale area. This
creates new channels within the rock from which natural gas is extracted at
higher than traditional rates. This drilling process can take up to a month,
while the drilling teams delve more than a mile into the Earth’s surface. After
which, the well is cased with cement to ensure groundwater protection, and the
shale is hydraulically fractured with water and other fracking fluids.
