Shale Reservoirs: Giant Resources for the 21st Century

    Shale reservoirs are not new. The first commercial hydrocarbon production in the United States was from a well drilled in 1821 in a shale gas reservoir. By 2000, more than 28,000 wells had been drilled in shale gas reservoirs. Rising gas prices and technological advancements in horizontal drilling and hydraulic fracturing associated with the development of the Barnett Shale led to a boom in ...

    Shale gas in the United States - Wikipedia

    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.

    Coalbed- and Shale-Gas Reservoirs - OnePetro

    Annual natural-gas production from coalbed- and shale-gas reservoirs in the US is approximately 2.7 Tscf, which represents 15% of total natural-gas production. Approximately 1.7 Tscf of this gas comes from more than 40,000 coalbed gas wells completed in at least 20 different basins.

    Geomechanical Properties of Unconventional Shale Reservoirs

    However, in order to predict the performance of a shale gas reservoir, implementing accurate shale rock properties is essential for developing a geologic model for the entire asset. Hence, it is very critical to access more data while working on an unconventional reservoir.

    Shale Gas Australia | Shale

    Shale gas is usually held at depths of more than 2000 metres – well below the reservoirs used for agriculture and town water supplies. The parts of Australia considered most likely to hold commercial deposits of natural gas in shales are in remote regions of Western Australia, South Australia, Queensland and the Northern Territory.

    Unlike conventional gas reservoirs, shale's pore size distribution is in the order of micron to nanometer causing seepage of gas molecules to dominate the gas flow. In such a flow condition, formation permeability is not con-stant anymore and depends on the pressure. The gas slippage known as Klinkenberg effect is very significant

    What is Shale Gas? - geology

    Shale Gas vs. Conventional Gas. Conventional gas reservoirs are created when natural gas migrates toward the Earth's surface from an organic-rich source formation into highly permeable reservoir rock, where it is trapped by an overlying layer of impermeable rock. In contrast, shale gas resources form within the organic-rich shale source rock.
