While the Dunkard Creek fish kill remains a highly contested issue, the environmental disaster was one of a number of early warning events alerting communities to the unknown risks of shale gas drilling in regions with a long history of coal extraction.
Coal bed methane (CBM): Methane occurs naturally underground within coal reserves. It can be extracted using a variety of techniques. In comparison to shale gas, the amount of gas we might get from CBM seems to be fairly small – maybe around three years of UK natural gas supply, according to the British Geological Survey .
Is shale gas greener? ... That is because coal that would have been used to fire power plants in the US has been exported instead, flooding the world market with cheap coal and encouraging far ...

Organic sedimentary rocks such as coal, some dolomites, and some limestones, form from the accumulation of plant or animal debris. ... Shale is a clastic sedimentary rock that is made up of clay-size (less than 1/256 millimeter in diameter) weathering debris. It typically breaks into thin flat pieces.
Oil Shale Coal Uploaded by ahmed1581973 This paper deals with all solid sedimentary fossil fuels, i.e. coal, the main one for geological reserves and resources, peat, and oil shales.
Siltstone and shale, two types of sedimentary rock called clastic rock, form from "clasts" -- that is, fragments of other rocks or minerals. When the rock fragments are buried and compacted, they form sedimentary layers.
Home » Science & Innovation » Oil & Gas » Shale Research & Development UNCONVENTIONAL OIL AND NATURAL GAS America's abundant unconventional oil and gas (UOG) resources, which include natural gas and oil contained in shale formations, are an important part of a balanced and sustainable national energy strategy.
The Carboniferous Period lasted from about 359.2 to 299 million years ago* during the late Paleozoic Era. The term "Carboniferous" comes from England, in reference to the rich deposits of coal that occur there. These deposits of coal occur throughout northern Europe, Asia, and midwestern and eastern ...
· "I will cancel job-killing restrictions on the production of American energy, including shale energy and clean coal, creating many millions of high-paying jobs," he said.
In 2007, before the expansion of shale gas production, employment in Pennsylvania's coal mining industry was larger than employment in the state's oil and natural gas industry. However, the same was not true at the level of the national economy, where, from 2007 to 2012, the oil and natural gas industry was consistently larger than the coal ...
· But the switch from coal-to-gas is not without its critics, especially those who say that the shale-gas boom is preventing the escalation of much cleaner fuels such as …
A view of the coal-fired Belchatow power plant on September 28, 2011 in Belchatow, central Poland. Central European powerhouse Poland will anchor its energy strategy in coal and shale gas, with ...
Cana-Woodford Shale - The Cana Woodford Shale is located in Western Oklahoma. This area has become a rather nice oil play with many companies below striking oil in their acreage. While the Cana Woodford Shale is mostly liquids rich in oil, natural gas is found there as well.
Environmental Impacts of Natural Gas The Future of Natural Gas Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas power plant compared with emissions from a typical new coal plant [ 1 ].
Once the fracking process is complete and the gas has been extracted, burning shale gas releases significantly less carbon dioxide than burning coal - about 50% less, in fact. In the years since fracking has become commonplace in the USA, carbon emissions have fallen significantly.
Most likely, shale gas also comes with a smaller GHG footprint than coal. However, shale gas extraction can affect water safety. This paper also discusses related aspects that exemplify how shale gas can be more beneficial in the short and long term.
Coal, oil shale, natural bitumen (tar sand), and heavy oil all belong to the group of fossil fuels. Peat is usually not classified as a coal, but can be seen as the precursor of coal.
Adsorption. The matrix systems of CBM and shale reservoirs have immense capacity for methane storage. The mechanism by which this occurs is called adsorption.In adsorption, molecules of gas become attached to the surface of coal or to organic material in shale.
· Shale natural gas resources are found in shale formations that contain significant accumulations of natural gas and/or oil. These resources, or plays, are found in about 30 states. The Barnett Shale in Texas has been producing natural gas for more than a decade.
The Marcellus Shale Coalition (MSC) works with exploration and production, midstream, and supply chain partners in the Appalachian Basin and across the country to address issues regarding the production of clean, job-creating, American natural gas from the Marcellus and Utica Shale plays.
Shale gas and coal bed methane 5 Potential sources of sustained energy in the future Shale gas: Shale gas is a natural gas produced from shale rock contained
Shale and coal. Shale oil was why Addiewell was built. Built in the 1860s, its oil works was the largest in the world. Its houses were built to accommodate the shale miners and oil workers employed by Young's Paraffin Light and Mineral Oil Company Ltd.
Well coal and shale are both organic rich sedimentary rocks with hydrocarbons. I think the difference is in their colors. shale contains quartz and calcite particles. They are both usable at raw state but more pressure needs to be applied to become oil.
Oil shale may contain between 60 and 90% mineral matter (non-organic), while coal will contain, by definition, less than 40%. The kerogen within oil shale is also of different organic composition than coal, which enjoys a more matured organic makeup that is lower in hydrogen and higher in oxygen than oil shale …
An attempt this past week to set up shale gas vs. coal in a way that equates the two fell flat as videographer Scott Cannon distorted the record. This past week videographer and veteran fractivist, Scott Cannon, gave a presentation to a handful of people in at American Legion Post 477 in Pittston ...

Coal currently tops the charts as the largest source of electricity in the world. Indeed in the US in January 2018, 31.8% of electricity was…
Shale gas, shale oil, tight gas and coal-bed methane are unconventional forms of gas and oil found in shale reservoirs and coal-beds. The extraction process often requires high-volume hydraulic fracturing, also known as 'fracking'.
Like traditional petroleum, natural gas, and coal, oil shale and kerogen are fossil fuels. Fossil fuels developed from the remains of algae, spores, plants, pollen, and a variety of other organisms that lived millions of years ago in ancient lakes, seas, and wetlands.
But, 'underground coal gasification', can create 6,900 trillion cubic feet of gas which is way HIGHER than shale reserves. India's shale resources at a more modest 65 trillion cubic feet. India's CBM potential is estimated at 450 tcf.
