What is Fracking? | | Shared as eductaion material
Fracking in Short
Fracking also referred to as a “frac job” or “frac unit” is the shorthand for hydraulic fracturing and refers to how the rock is fractured apart by the high pressure mixture.
Hydraulic fracturing is the process of drilling for natural gas and oil underneath the ground and creating tiny explosions to shatter and crack hard shale rocks to release the gas inside. Water mixed with other components( sand and chemicals) is pumped into the ground rock at high pressure to create cracks (also referred to as fissures or fractures) to release the gas this allows the gas to flow out to the head of the well. The process is carried out vertically or, more commonly, by drilling horizontally to the rock layer. The process can create new pathway /”frac unit”s to release gas or can be used to extend existing channels.
Further Facts On Fracking
Much of the water used in fracking is collected from the well and processed, but there are concerns that carcinogenic chemicals will escape and find their way into drinking water sources.
An independent geological report has found that it is “highly probable” that fracking, triggered two minor earthquakes on the Lancashire coast earlier this year. Two small earthquakes of 1.5 and 2.2 magnitude hit the Blackpool area this year and fracking operations have now been suspended pending an investigation.
There are also claims that shale gas leaking into their drinking supply causes tap water to ignite. Shale gas also presents a problem for global warming, because it is an abundant fossil fuel that could be a cheaper substitute than many renewable energy sources. However, carbon (and noxious gas) emissions from natural gas are much lower than from oil and coal.
