The shale is a light to medium gray rock. It has slaty cleavages. The shale has a dull luster and is composed mostly of quartz and clay. The grain size is fine with a smooth texture. It has distinctive compositional horizontal bedding of about 2.2cm (light gray) to 12cm (dark gray) in thickness. The bedding is horizontal and parallel to the ground with a thickness of approximately 16cm to 24cm.
The Britannia Mines has played such a major role in the building blocks of British Columbia’s economic development and early history. Behind the unforgotten community that once flourished with 60,000 miners of different races and religions, lies a rich history that captures the hearts of many who pass by one of the most successful copper sites of its time. With that being said, the legend behind the discovery of affluent minerals in Britannia Mines is by a doctor who was searching for gold in the year, 1888. After many failed attempts to set up a mining industry, the Britannia Mine and Smelting Company Ltd. took interest in this discovery and developed operation systems and communities. The Britannia Mines in the 1920s became such a successful
What is Marcellus Shale? It is a marine sedimentary rock buried thousands of feet beneath the earths surfaces. Sedimentary rock is one of the three main rock groups and is formed in four main ways: by the deposition of the weathered remains of other rocks; by the accumulation and the consolidation of sediments; by the deposition of the results of biogenic activity; and by precipitation from solution. Marcellus Shale is found throughout the Allegheny Plateau region of the northern Appalachian basin of North America. It stretches from upstate New York south through Pennsylvania to West Virginia and west to parts of Ohio. Marcellus shale was named after a town in upstate New York, the rock itself is millions of years old, formed from mud and other natural materials. Its made up of the formation of black shale that may contain lime stone beds and concentrations of iron pyrite and siderite. The Sedimentary beds and structure is very well developed. Lighter colored shales in the upper portion of the formation tend to split into small thin edged fragments after exposure. The fragments may have and leave rust stains from exposure of pyrite to air, and tiny gypsum crystals from the reaction between both of the fragments pyrite and the limestone particles. Fresh exposures of the pyriteiferous shale may develop the secondary mineralization of orange limonite and the pale yellow efflorescence or bloom of sulfur, associated with acid
The Burgess Shale, located in Yoho National Park, British Columbia, was discovered by Charles D. Walcott in 1909. Walcott spent 18 years collecting and classifying the fossils located at this site. The Shale was formed about 530 million years ago, in the Cambrian Period.
I found it interesting that the acid produced from the mine can burn fabrics and skin. Also that the acid created by the mine is known for having the worst concentration of acid in the world and is about 500 times more acidic than any other mine. The mine is so dangerous that they have to pump air in just so people don't pass out. The greediness of humans and their action caused this catastrophe and its us that need to stop it from creating any further damage. People can help by donating to charities or being green. I think that if everyone works together this problem will be shortly minuscule as I believe the EPA will be able to bring acid levels down with
The Eagle Ford shale formation in south Texas has recently become the focus of many oil industry operators searching for new sources of hydrocarbons by using the latest technology in previously unexplored areas. This exploration enhances the development of even more advanced techniques as issues are identified and problems solved to address the unique properties of the formation and the surrounding surface environment. Even though a formation may be comprised of a single sedimentary layer from a similar geological time frame it is not a homogeneous block and has many features and anomalies that effect the pressure, permeability, type of hydrocarbons trapped and methods required to extract them. To understand these properties one must understand that shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay placing it in the mudstone category of rocks [1]. Shale is different from other rocks in this category because it has a fissile structure and is laminated. The black shale in the Eagle Ford formation (Fig 1.) has a special property such that it contained organic material when it was deposited and during compaction over a millennium, the organic materials were converted into trapped oil and gas hydrocarbon deposits. This oil and gas are very difficult to remove because it is trapped within tiny pore spaces and or adsorbed onto clay mineral particles that makeup the shale.
Coal seam gas opens up a massive industry which would be capable of holding many more workers. There would be a number of different types of jobs involved in the process resulting in a variety of choices for possible employees.
In the year 2045 the Hillside Mine was closed down due to the number of complaints against the place.
“The Utica shale is a black, calcareous, organic rich shale of Middle Ordovician age”(King). It is found under Marcellus Shale and is located in Ohio, Pennsylvania, West Virginia, New York and parts of eastern North America. Utica is a couple thousand feet below Marcellus Shale. Utica has large amounts of natural gas, crude oil and natural gas liquid. The United States Geological Survey estimates about 38 trillion cubic feet of natural gas, 940 million barrels of oil and 208 million of natural gas liquids. The formation is interesting due to its vast size and depth. Also, the gas and oil has very low permeability that
On June 8, 1917, one of the most devastating disasters in Montana took place. Over 160 miners died, this disaster being the Great Butte Mining Disaster of 1917. It was truly a devastation…
The Haynesville shale in Louisiana is one of several unconventional gas plays that have been discovered in the U.S. in the past decade and promise to dramatically change the course of future energy development given its enormous resource potential. Unconventional gas resources are abundant, but their development is particularly sensitive to technologic risk, geologic uncertainty, and gas price. To produce at commercial rates, shale gas wells require horizontal drilling and hydraulic fracturing which significantly increases the capital cost. The purpose of this paper is to examine the price sensitivity of Haynesville wells and the economic viability of the play. We characterize the operating envelope under which Haynesville wells are economic
The Marcellus Shale is a geologic formation of shale rock buried deep underground which lies beneath 95,000 square miles of land beneath Pennsylvania, New York, Virginia and Ohio and lies at depth of over 9000 ft. It is primarily known for the huge deposit of natural gas that is found within small openings within the rock. In order to access this gas in greater amounts, companies will create more fissures through a process called hydraulic Fracturing or “fracking”. Natural gas can heat homes, fuel cars and is considered to be the most viable source of alternative energy.
Marcellus Shale, also known, as the Marcellus Formation, is black, organically rich, shale that exists underneath the surface of West Virginia, Pennsylvania, New York, Ohio, Kentucky, Maryland, Tennessee, and Virginia. The shale is located roughly one mile below the surface of these states and has an estimated 141 trillion cubic feet of attainable natural gas. As of 2015, Marcellus shale gas wells were reportedly yielding 14.4 billion cubic feet of natural gas per day (“Marcellus Shale - Appalachian Basin Natural Gas Play”). This shale discovery is known as one of the largest natural gas reserves in the United States, and this underground gas is now reachable thanks to hydraulic fracturing and horizontally drilling. These two techniques, when used in combination, have enabled gas producers to extract shale gas both rapidly and economically” (“The Marcellus Shale Gas Boom”). Although, there are many myths and disagreements with the way America gets this natural gas, it has proven to have more advantages than disadvantages.
The Marcellus shale is a Middle Devonian primary source rock in the Appalachian basin as well as an unconventional reservoir rock.The Marcellus shale is produced through the implementation of horizontal drilling and hydraulic fracture stimulation.
14,000 feet in elevation, I was about to hike up, Matterhorn, one of the highest peaks in the world, and the air was a brisk -7 ℉. A pall fell over the previously greyish-blue sky of the Swiss Alps as a violent snowstorm was forming in the distance. There was a light blue cover of snow forming over the base of Matterhorn Mountain in the Swiss Alps. The guide at the base recommended we put our hike on hold due to poor weather conditions and extreme avalanche warnings, but as arrogant teenagers, we decided not to listen.
Background Information The Marcellus Shale remains one of the most prolific plays in North America, in terms of both acreage and reserve potential. It is among the fastest growing sources of natural gas production in the United States, rising from less than 1.7 Bcf/d at the beginning of 2010 to 16.4 Bcf/d in July 2015. In Pennsylvania alone, according to state data, operators produced more than 4 Tcf of natural gas -- mostly from the Marcellus Shale -- in 2014 (see Shale Daily, Feb. 17, 2015). While a commodities downturn was expected to push production down to roughly 15.9 Bcf/d heading into the end of 2015, according to the EIA, the Northeast is still expected to drive a significant portion of the country's natural gas production in 2016
