Especially as nations seek lower-carbon fuels while ensuring energy security and economic development.
Demand for natural gas is expected to account for nearly 24 percent of global energy supplies by 2020.
With increase in demand for gas, supplies from conventional sources are depleting- hence driving the gas industry to unconventional sources, such as shale.
“The confluence of growing demand and breakthrough technological advancements has made investments in shale plays attractive in recent years. Advancements in directional drilling and hydraulic fracturing technologies have enabled the achievement of high rates of gas production from deep, low permeability gas shale formations. These breakthroughs have facilitated access to some of the largest undeveloped gas resources in the world.
These technologies have been widely adopted in North America, resulting in dramatic increases in the production of shale gas. North American gas shales already produce over 9 billion cubic feet per day and are projected to continue to grow rapidly. Shale gas as a percentage of total North American gas production has increased from virtually nothing in 2000 to 13% in 2009; enabling the United States to eclipse Russia as the world’s leading producer of natural gas.
The success of shale gas production in North America, and particularly in the US, has accelerated the exploration of shale gas resources in other regions of the world. In 2009, the International Energy Agency estimated that global recoverable resources of shale gas exceed 6,350 trillion cubic feet (Tcf). In Europe, significant gas shale resources have been identified in Poland, Sweden, and Austria. A number of gas shale basins have also been identified in Australia, China, India, and Southern African nations.
