Shale Gas and Its Uses

Shale Gas & It's Uses sponsored by How does it differ from conventional gas? Where conventional gas comes from source rocks thousands of meteres beneath the ARDVIK What is it? http://www.ardvik.com Shale gas is a natural gas, consisting mainly of methane, which is recovered from rocks. Earth's surface and is considered easy to extract, shale gas is artifically fractured or 'fracked' which is a more controversial process How it's extracted Sand in the water is used to Water is then pumped into the borehole at A borehole is then First, the prop open the fracture, drilled into amount of shale in a rock unit is determined the rock at create a carefully selected site. pressure high enough to fracture the permeability and allow the gas to flow into the surrounding rock. borehole where it can be recovered. How does this affect or benefit the UK? There is potentially enough meet the UK'S energy One of the risks is induced seismisicity; fracking caused low level earthquakes in Lancashire in 2011.The The UK holds several different rock units that have the shale gas to potential to produce shale gas. Carboniferous units such as the Bowland Shale Formation found needs for decades to throughout north-west, central and eastern England, are so far proving successful in shale explorations come. However, the problem that mining companies face is exactly how much of the shale gas can be process also holds the potential for groundwater and surface water contamination due to recovered. spillage of the chemicals used in fracking.
