Shale Gas Essay

The world is increasingly taking interest in the potential for a shale gas revolution. Australia is no exception to this trend. The key question for Federal, State and Local Government is, assuming a shale gas revolution is seen as desirable, what policy measures maybe taken in order to achieve this end and what should any debate over shale gas policy be focusing upon? This brief paper sets the context of the shale gas revolution. It then outlines the characteristics present in the USA that generated their shale gas revolution. In the context of Australia, there are a great many barriers to reproducing these characteristics. The paper considers what policy options are available to reduce such barriers and lead to an Australian shale gas revolution.



The shale gas revolution in the USA is based upon the application of two main technologies – horizontal drilling and hydraulic fracturing (frack ing). Neither is new technology. Horizontal drilling was developed in the 1930s and the first well was fracced in the USA in 1947. The revolution has been reflected in the dramatic increase in the production of shale gas. In 2000 shale accounted for less than 1 percent of US domestic gas production. In 2007 it was 8 percent and only four years later, in 2011, it was 30 percent. However, a key point is that this American “revolution” in reality happened over a long period of time – well over 20 years in the making, although it is only in the last five years or so that the share of shale gas in domestic production has increased significantly. Furthermore, this growing role of shale gas is expected to continue. The EIA suggests shale gas will supply 42 percent of domestic gas production by 2040 and another source puts shale at over 50 percent by the 2030s .


The impact of this shale gas revolution has been significant . The most obvious impact has been on USA domestic gas prices as can be seen from Figure 1.

This dramatic fall in gas prices has had several important effects. It has led to a significant revival in USA petrochemical and other gas intensive manufacturing industries. It has also pushed coal out of much electricity generation, leading to increased coal exports and a reduction in the USA’s carbon footprint. Internationally, it has had a huge impact on the global LNG trade. Between 2005 and 2009, 75 percent of USA LNG regasification capacity was built in anticipation of falling domestic USA gas supplies. By 2011, 90 percent of total capacity was idle. At the same time, LNG export plants which had been built in anticipation of greater US demand suddenly found themselves scrabbling for alternative markets. The result was a potential oversupply of LNG leading to downward pressure on prices .

940 words - 4 pages In recent years, it is becoming more apparent that a healthy alternative to the fossil fuels we so frivolously use is now more critical than ever. In 2011, the United States used 18.83 million barrels of raw oil daily, and in 2010 19.18 million barrels of petroleum products and biofuels. In 2010 and 2011, that was nearly 22% of the worlds oil supply. (U.S Department of Energy) Previously inaccessible energy sources such as shale gas methane are

One proposed option is shale gas produced through a process called hydraulic fracturing, or “fracking.” But this energy source is highly polarizing, with strong advocates and detractors. While there are many who believe hydraulic fracturing should not be used in the quest for natural resources, the process has a relatively low impact on the environment, and the shale gas that it produces has the potential to change

Is America Fracking Crazy?

1863 words - 7 pages .  Because of this, the recent development of natural gas extraction from shale rock, by the means of hydraulic fracturing has been discovered. The main objective of the process of hydraulic fracturing is to access oil and gas resources that are locked in non-porous rock (Howarth, Ingraffea, and Engelder 3). The main type of rock surface that is used in this process is shale rock due to its vast amounts of trapped natural gas mostly consisting of

Big oil companies such as Halliburton have started extracting the natural gases that mainly consist of methane, through a process called hydraulic fracturing. Although it seems like natural gas may save the United States from an energy crisis, many opponents to hydraulic fracturing exist because it

Hydraulic Fracturing: The Future of America’s Energy

1375 words - 6 pages Hydraulic Fracturing, also known as fracking, is not a novel concept. The hope of being able to access fossil fuels trapped inside layers of shale deep beneath the Earth’s surface was achieved by the process of fracking, developed in 1903 ( Over the last century, hydraulic fracturing has become an efficient and environmentally friendly way to access the natural gas needed to meet the United States’ high demands.
