Kingston, Ontario
Kingston is a city in Ontario, Canada. It is located on the north-eastern end of Lake Ontario, at the beginning of the St. Lawrence River and at the mouth of the Cataraqui River (south end of the Rideau Canal). The city is midway between Toronto, Ontario and Montreal, Quebec. Kingston is also located nearby the Thousand Islands, a tourist region to the east, and the Prince Edward County tourist region to the west. Kingston is nicknamed the "Limestone City" because of the many heritage buildings constructed using local limestone. Growing European exploration in the 17th century, and the desire for the Europeans to establish a presence close to local Native occupants to control trade, led to the founding of a French trading post and military fort at a site known as "Cataraqui" (generally pronounced /kætə'ɹɑkweɪ/, "kah-tah-ROCK-way") in 1673. This outpost, called Fort Cataraqui, and later Fort Frontenac, became a focus for settlement. Since 1760, the site of Kingston, Ont ...

Rockburst
A rock burst is a spontaneous, violent failure of rock that can occur in high-stress mines. Although mines may experience many mining-related seismic events, only the tremors associated with damage to accessible mine workings are classified as rock bursts. The opening of mine workings relieves neighboring rocks of tremendous pressure, which can literally cause the rock to explode, or trigger abrupt movement on nearby geological structures. Rock bursts are a serious hazard; in South Africa, they kill roughly 20 miners each year. Details Rock bursts result from brittle fracturing of rock, causing it to collapse rapidly with violent spalling of rock that is approximately 100 to 200 tonnes, or more. This release of energy reduces the potential energy of the rock around the excavation. Another explanation is that the changes brought about by the mine's redistribution of stress trigger latent seismic events, deriving from the strain energy produced by its geological aspects. The ...

Steam Injection (oil Industry)
Steam injection is an increasingly common method of extracting heavy crude oil. Used commercially since the 1960s, it is considered an enhanced oil recovery (EOR) method and is the main type of thermal stimulation of oil reservoirs. There are several different forms of the technology, with the two main ones being Cyclic Steam Stimulation and Steam Flooding. Both are most commonly applied to oil reservoirs, which are relatively shallow and which contain crude oils which are very viscous at the temperature of the native underground formation. Steam injection is widely used in the San Joaquin Valley of California (US), the Lake Maracaibo area of Venezuela, and the oil sands of northern Alberta,Canada. Another contributing factor that enhances oil production during steam injection is related to near-wellbore cleanup. In this case, steam reduces the viscosity that ties paraffins and asphaltenes to the rock surfaces while steam distillation of crude oil light ends creates a small ...

Marcellus Formation
The Marcellus Formation or the Marcellus Shale is a Middle Devonian age unit of sedimentary rock found in eastern North America. Named for a distinctive outcrop near the village of Marcellus, New York, in the United States, it extends throughout much of the Appalachian Basin. The unit name usage by the U.S. Geological Survey (USGS) includes ''Marcellus Shale'' and ''Marcellus Formation''.See unit names marked by an asterisk aGeolex/ref> The term "Marcellus Shale" is the preferred name throughout most of the Appalachian region, although the term "Marcellus Formation" is also acceptable within the State of Pennsylvania. The unit was first described and named as the "Marcellus shales" by J. Hall in 1839. Description The Marcellus consists predominantly of black shale and a few limestone beds and concentrations of iron pyrite ( Fe S2) and siderite (Fe CO3). Like most shales, it tends to split easily along the bedding plane, a property known as fissility. Lighter colored ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horn River Formation
The Horn River Formation (also ''Horn River Shale'') is a stratigraphic unit of Devonian (early Givetian to late Frasnian) age in the Western Canadian Sedimentary Basin. It is a thick sequence of marine sediments that was first described in outcrop on the banks of the Horn River, a tributary of the Mackenzie River, in the Northwest Territories (at the time District of Mackenzie) by Whittaker in 1922, and it takes its name from that river. In 1963 it was redefined in the subsurface of the Fort Nelson area of British Columbia (well Fort Nelson a-95-J/94-J-10) by F.F. Gray and J.R. Kassube. It is significant for its shale gas resources. Lithology The Horn River Formation is composed of dark siliceous and calcareous shale, and argillaceous bituminous limestone. Stratigraphy The Horn River Formation is included in the Beaverhill Lake Group. It is subdivided into the following members, from top to base: * Muskwa Member: bituminous, mildly radioactive shale * Otter Park Member ...

Hydraulic Fracture
Fracking (also known as hydraulic fracturing, hydrofracturing, or hydrofracking) is a well stimulation technique involving the fracturing of bedrock formations by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures open. Hydraulic fracturing began as an experiment in 1947, and the first commercially successful application followed in 1950. As of 2012, 2.5 million "frac jobs" had been performed worldwide on oil and gas wells, over one million of those within the U.S. Such treatment is generally necessary to achieve adequate flow rates in shale gas, tight gas, tig ...

Oil Sands
Oil sands, tar sands, crude bitumen, or bituminous sands, are a type of unconventional petroleum deposit. Oil sands are either loose sands or partially consolidated sandstone containing a naturally occurring mixture of sand, clay, and water, soaked with bitumen, a dense and extremely viscous form of petroleum. Significant bitumen deposits are reported in Canada, Kazakhstan, Russia, and Venezuela. The estimated worldwide deposits of oil are more than ; the estimates include deposits that have not been discovered. Proven reserves of bitumen contain approximately 100 billion barrels, and total natural bitumen reserves are estimated at worldwide, of which , or 70.8%, are in Alberta, Canada. Crude bitumen is a thick, sticky form of crude oil, so viscous that it will not flow unless heated or diluted with lighter hydrocarbons such as light crude oil or natural-gas condensate. At room temperature, it is much like cold molasses. The Orinoco Belt in Venezuela is sometimes des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Retsof, New York
Retsof is a hamlet and census-designated place (CDP) within the town of York in Livingston County, New York, United States. The community, situated southwest of the city of Rochester, is off New York State Route 63 approximately one mile east of State Route 36. As of the 2010 census, it had a population of 340. It was founded by a man named William Foster, Jr., who reversed the letters of his name to name the town, and it was the site of one of the world's largest salt mines until its collapse in 1994. A new mine, the Hampton Corners mine, is located near Mount Morris, about to the southeast. The original population of Retsof was mostly of Italian origin; they lived in a company town where the salt mine owned the houses and a store and maintained the small village. The Italian families lived together with a few non-Italians. The others who were mostly bosses lived on the "Avenue" in nicer houses with indoor plumbing. In addition to the salt mine, there was a small railr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
