20 Nov 2014 This is very different than shale reservoirs. In these systems the source rock and the reservoir rock are the same and they have very low  Gas-producing shales are predominantly composed of consolidated clay-sized particles with a high organic content. High subsurface pressures and temperatures convert the organic matter to oil and gas, which may migrate to conventional petroleum traps and also remains within the shale. However, the clay content severely limits gas and fluid flow within the shales. In the past 20 years, despite the extraction of almost 50 billion barrels and 475 trillion cubic feet, proven oil reserves have increased 66% to over 50 billion barrels and proven gas reserves

Shale gas is natural gas that is found trapped within shale formations. Shale gas has become China is estimated to have the world's largest shale gas reserves. Along with other forms of unconventional energy, shale oil and gas extraction has three direct initial aspects: increased labour demand (employment); income  Oil shale reserves refers to oil shale resources that are economically recoverable under current on the price of conventional oil; if the price of crude oil per barrel is less than the production price per barrel of oil shale, it is uneconomic.

26 Dec 2017 Due to the ultralow permeability of shale gas reservoirs, stimulating the is the saturations of gas, are the mole densities of oil and gas, is the  Current Methods of Extraction. Recently, oil and gas companies have been extracting these resources from unconventional reservoirs, such as shale formations.

Some analysts expect that shale gas will come to play an expanding role in world energy supply with potential shale gas and shale oil reservoirs in India, 

22 Nov 2011 Many of today's oil & gas reservoirs are to be found in increasingly difficult locations with complex geologies. These locations include: Reservoirs  20 Nov 2014 This is very different than shale reservoirs.

In the past 20 years, despite the extraction of almost 50 billion barrels and 475 trillion cubic feet, proven oil reserves have increased 66% to over 50 billion barrels and proven gas reserves Shale gas in the United States is rapidly increasing as an available source of natural gas.Led by new applications of hydraulic fracturing technology and horizontal drilling, development of new sources of shale gas has offset declines in production from conventional gas reservoirs, and has led to major increases in reserves of US natural gas.Largely due to shale gas discoveries, estimated Estimated shale oil and shale gas resources in the United States and in 137 shale formations in 41 other countries represent 10% of the world's crude oil and 32% of the world's natural gas technically recoverable resources, or those that can be produced using current technology without reference to economic profitability, according to a new EIA-sponsored study (see Table 1) released today What Triggered the U.S. Shale Gas Revolution? The use of horizontal drilling in conjunction with hydraulic fracturing has greatly expanded the ability of producers to profitably produce natural gas from low-permeability geologic formations, particularly shale formations. Application of fracturing techniques to stimulate oil and gas production began to grow rapidly in the 1950s, although
