Shale play

Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as "mudstones." Shale is distinguished from other mudstones because it is fissile and laminated.

Shale Gas

Mar 04, 2013· Oil shale is a type of sedimentary rock that is rich in kerogen. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Hydrocarbons are substances made entirely of hydrogen and carbon. Petroleum and natural gas are probably the most familiar hydrocarbons. The hydrocarbons in oil shale can be used as an alternative to petroleum or natural gas.

Oil Shale

Individual coal or shale pieces were place one at a time between the parallel plates P1 and P2 of the apparatus shown. These plates constituted a parallel-plate capacitor which, together with variable capacitance C1 and appropriate inductor L1, formed a circuit which could be resonated at a convenient radio frequency (ca. 10 MHz). ...

The Biggest Problem Behind The U.S. Shale Boom | OilPrice

Coal resource production requires at least twice as much water per million British thermal units compared to shale gas production. And while regions like Pennsylvania have experienced an absolute increase in water demand for energy production thanks to the shale boom, shale wells actually produce less than half the wastewater per unit of energy ...

The Difference Between Shale Oil and Oil Shale

Oil shale has received many different names over the years, such as cannel coal, boghead coal, alum shale, stellarite, albertite, kerosene shale, bituminite, gas coal, algal coal, wollongite, schistes bitumineux, torbanite, and kukersite. Some of these names are still used for certain types of oil shale.

Shale vs Coal

Aug 15, 2011· And both coal seam gas and shale gas produce about half the CO₂ of brown coal. In North America today, about 20-25% of the total gas consumed comes from shale gas deposits.

Natixis exits coal but remains stuck in shale oil & gas

shale as being a 'hybrid' of oil and coal. Oil shale contains more kerogen than oil source rock, but less than coal. The composition of the oil derived from oil shale is much more similar to the composition of petroleum than to coal. Some oil shales can be ignited, like

Shale: Sedimentary Rock

If NOAA is right, then shale gas could be more polluting than coal. But there is now other research out there that disagrees – for example a peer-reviewed study part-funded by ExxonMobil used a life cycle assessment of shale gas to conclude that the carbon footprint is shale gas is 53 per cent lower than coal.
