What are the advantages of shale gas?
It notes that done properly, shale gas development can enhance energy security and the availability of energy fuels, lower natural gas prices, offer a cleaner environmental footprint than some other fossil fuels, and enable local economic development.
What is meant by shale gas?
Shale gas refers to natural gas that is trapped within shale formations. Shales are fine-grained sedimentary rocks that can be rich sources of petroleum and natural gas (see Fig. 1.4). Shale gas is trapped within the pores of this sedimentary rock.
What is shale gas and why is it important?
Shale gas is natural gas that is found trapped within shale formations. Shale gas has become an increasingly important source of natural gas in the United States since the start of this century, and interest has spread to potential gas shales in the rest of the world.
What is shale gas and how is it formed?
Shale gas is a form of unconventional hydrocarbons because the rock it is extracted from acts as the source, reservoir and cap rock. The gas is produced, stored and sealed within impermeable shale and can be released only after the shale is drilled and artificially fractured during an extraction process.
What are disadvantages of shale gas?
The result is “a super-salty brine, prone to bacterial growth, and potentially contaminated with heavy metals,” the National Geographic wrote in its series on shale gas. Furthermore, the large amount of water needed to drill for shale can affect water availability for other uses, potentially impacting aquatic habitats.
What shale means?
Definition of shale : a fissile rock that is formed by the consolidation of clay, mud, or silt, has a finely stratified or laminated structure, and is composed of minerals essentially unaltered since deposition.
Does India have shale gas?
As per the US EIA 2015 report, India has got technically recoverable shale gas of 96 trillion cubic feet. The recoverable reserves are identified in Cambay, Krishna – Godavari, Cauvery, Damodar Valley, Upper Assam, Pranahita – Godavari, Rajasthan and Vindhya Basins.
Why is shale gas bad?
But US researchers found that shale gas wells leak substantial amounts of methane, a potent greenhouse gas. This makes its climate impact worse than conventional gas, they say – and probably worse than coal as well.
Is petroleum a shale gas?
Shale gas refers to natural gas that is trapped within shale formations. Shales are fine-grained sedimentary rocks that can be rich sources of petroleum and natural gas.
Which country is largest producer of shale gas?
the United States
In 2015, the United States produced some 37 billion cubic feet per day of shale gas, making it the world’s largest producer of shale gas.
Is shale and fracking the same?
Shale oil refers to hydrocarbons that are trapped in formations of shale rock. Fracking is a process that oil companies use to drill down into the layers of shale and open up the rock formations so that oil can be extracted. Fracking is done by several companies, including Halliburton Company (HAL), Chevron Corp.
What are the benefits of using shale gas?
Shale gas also provides feedstock for the petrochemicals industry, which is turned into plastics, fertiliser and other useful stuff. Experimental Usage as fuel for trucks, lorries and buses. Shale-gas is cheaper than gas, releases 50% less CO 2, hence better source for generating electricity.
What are the environmental disadvantages of shale oil?
Another environmental disadvantage to extracting shale oil is the enormous amounts of freshwater required. Water is necessary for drilling, mining, refining, and generating power. Some experts estimate that three litres (.8 gallon) of water are required to produce just one litre (.3 gallon) of shale oil.
Can you use oil shale as an alternative to natural gas?
The hydrocarbons in oil shale can be used as an alternative to petroleum or natural gas. Like traditional petroleum, natural gas, and coal, oil shale and kerogen are fossil fuels.
What’s the difference between oil shale and shale oil?
Oil shale, shale oil, and oil-bearing shale are three different substances. Oil shale is a sedimentary rock. As it reaches its oil window, oil shale releases a liquid known as shale oil. Oil shale is the rock from which shale oil is extracted.
