In the 1990s the extraction of unconventional shale gas extraction increases in the USA due to national and global demand of energy. The expansion of shale gas production will provide low carbon economy, therefore it is a positive side of low greenhouse gas emissions in the atmosphere and considering the benefit sides it has been referred to as a bridging fuel. Horizontal drilling and hydraulic fracturing are the two technologies by the combination with one another; provide the potential to unlock tighter shale gas formations. The conventional natural gas reserves declining globally, so that shale gas extraction emerged as a potentially significant new source of unconventional gas in the USA, the UK and elsewhere. This paper discusses the procedure of extraction, benefits and disadvantages of unconventional shale gas.
