Shale Gas
Shale gas is natural gas produced from shale (rock layer caprock). Shale gas into the
source of an important and increasing in the United States last ten years. The desire is
to spread to areas shale gas potential in Canada, Europe, Asia and Australia. One
analysis estimates that shale gas will supply half of natural gas production in North
America in 2020. Another analysis of shale gas will be rapidly growing in the world as a
source of energy. Baker Institute of Public Policy at Rice University concluded that
increased production of shale gas in the United States and Canada will assist in
preventing Russia and the countries of the Gulf region in the Middle East from high gas
prices that will be exported to European countries.
Obama's Cabinet in the United States believes that the Shale Gas will help reduce
greenhouse gas emissions. Because the properties of rocks usually have an impermeable
shale (not to drain the fluid), mostly shale does not contain natural gas. Shale gas is one
source of natural gas that is not conventional. Another example of sources that are not
conventional natural gas is coalbed methane, tight sandstones, and methane
hydrates. Shale gas has a low permeabillity matrix, the production of gas in commercial
kkwantitas need solving (fractures) to obtain the permeability, which is why Shale gas is
one source of unconventional natural gas.
Shale gas has been booming a few years using modern technology, namely hydraulic
fracturing to create an extensive artificial floating around the production wells (well
bore).Or Directional Drilling Horizontal drilling is often used nutmeg shale gas wells, with
a lateral length of around 10,000 ft (3,000 m) in a layer of shale.
Shale which has economic quantity of gas containing such property;
Organic-rich · 0.5% to 20%, and normally the case in the source rock that has
been cooked by heat and pressure which is converted into natural gas.
Having nature brittle and stiff enough to maintain the opening fractions.
In some areas of shale has a high interval of natural gamma radiation. The higher
the radiation can be corelated with a high content of organic carbon.
Some gas production is maintained with a natural solution, some of which are contained
in the pores of the rock, and some undergo a process of adsorbed into organic matter
