Arctic North Slope
The Alaska North Slope ( Iñupiaq: ''Siḷaliñiq'') is the region of the U.S. state of Alaska located on the northern slope of the Brooks Range along the coast of two marginal seas of the Arctic Ocean, the Chukchi Sea being on the western side of Point Barrow, and the Beaufort Sea on the eastern. Petroleum resources The Alaska North Slope region includes the National Petroleum Reserve–Alaska, with the bulk of Alaska's known petroleum until the Prudhoe Bay Oil Field was discovered in 1968, followed by the Kuparuk River oil field in 1969. The region also includes the Arctic National Wildlife Refuge, which itself has been the subject of controversy surrounding the possibility of petroleum drilling within its boundaries. The petroleum extracted from the region is transferred south by means of the Trans-Alaska Pipeline System to Valdez on the Pacific Ocean. Under the North Slope is an ancient seabed, which is the source of the oil. Within the North Slope, there is a geologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Valdez, Alaska
Valdez ( ; Alutiiq: ) is a city in the Chugach Census Area in the U.S. state of Alaska. According to the 2020 US Census, the population of the city is 3,985, up from 3,976 in 2010. It is the third most populated city in Alaska's Unorganized Borough. The city was named in 1790 after the Spanish Navy Minister Antonio Valdés y Fernández Bazán. A former Gold Rush town, it is located at the head of Port Valdez on the eastern side of Prince William Sound. The port did not flourish until after the road link to Fairbanks was constructed in 1899. It suffered catastrophic damage during the 1964 Alaska earthquake, and is located near the site of the disastrous 1989 Exxon Valdez oil tanker spill. Today, it is one of the most important ports in Alaska, a commercial fishing port as well as a freight terminal. Valdez is also the terminus for the Trans-Alaska Pipeline System. History The port of Valdez was named in 1790 by the Spanish explorer Salvador Fidalgo after the Spanish naval office ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tundra
In physical geography, tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. The term ''tundra'' comes through Russian (') from the Kildin Sámi word (') meaning "uplands", "treeless mountain tract". There are three regions and associated types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained g ...

Eskimo
Eskimo () is an exonym used to refer to two closely related Indigenous peoples: the Inuit (including the Alaska Native Iñupiat, the Greenlandic Inuit, and the Canadian Inuit) and the Yupik peoples, Yupik (or Siberian Yupik, Yuit) of eastern Siberia and Alaska. A related third group, the Aleut, which inhabit the Aleutian Islands, are generally excluded from the definition of Eskimo. The three groups share a relatively recent common ancestor, and speak related languages belonging to the Eskaleut languages, Eskaleut language family. These circumpolar peoples have traditionally inhabited the Arctic and subarctic regions from eastern Siberia (Russia) to Alaska (United States), Northern Canada, Nunavik, Nunatsiavut, and Greenland. Many Inuit, Yupik, Aleut, and other individuals consider the term ''Eskimo'', which is of a disputed etymology, to be unacceptable and even pejorative. Eskimo continues to be used within a historical, linguistic, archaeological, and cultural context. The g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noel Wien
Noel Wien (June 8, 1899July 19, 1977) was an American pioneer aviator. He was the founder of Wien Alaska Airways. Biography Wien was born in Lake Nebagamon, Wisconsin, but the family moved to a homestead in 1905, to a place now called Cook, Minnesota. In May 1921, he learned to fly a JN-4 in 8 hours, from Major Ray S. Miller, commander of the 109th Minnesota Air Squadron and manager of the Curtiss Northwest Airplane Company's flying school. Unable to pay the bond required to solo, Wien took a job with E.W. Morrill 15 June 1921, helping to fly and maintain his Standard J-1 while barnstorming. After a few more flying jobs, on 2 Sept. 1922, Wien had enough money to put a downpayment on a Thomas-Morse S-4, which he owned for two weeks, unable to make the final payment. Wien then started working for Clarence W. Hinck's Federated Flyers Flying Circus, earning $300 a month, before Hinck's sold out his operation in Jan. 1924. Wien was then hired by Jimmy Rodebaugh, in May 1924, to f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ira Harkey
Ira B. Harkey Jr. (January 15, 1918 – October 8, 2006) was an American writer, professor of journalism, and editor and publisher of the ''Pascagoula Chronicle-Star'' in Mississippi from 1951 to 1963. Harkey was awarded the Pulitzer Prize for Editorial Writing in 1963 for his anti-segregation editorials during the civil rights crisis surrounding the admission of James Meredith, a black man, to the University of Mississippi at Oxford, Mississippi in 1962. Life Ira Harkey was born in New Orleans, Louisiana, son of a wealthy businessman. He graduated from Tulane University, where he was a brother with the Delta Kappa Epsilon fraternity (Tau Lambda chapter), with an undergraduate degree in journalism in 1941 and then served aboard the aircraft carrier ''USS Hancock (CV-19)'' in the Pacific theater during World War II.

Shale Gas
Shale gas is an unconventional natural gas that is found trapped within shale formations. Since the 1990s a combination of horizontal drilling and hydraulic fracturing has made large volumes of shale gas more economical to produce, and some analysts expect that shale gas will greatly expand worldwide energy supply. 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. China is estimated to have the world's largest shale gas reserves. A 2013 review by the United Kingdom Department of Energy and Climate Change noted that most studies of the subject have estimated that life-cycle greenhouse gas (GHG) emissions from shale gas are similar to those of conventional natural gas, and are much less than those from coal, usually about half the greenhouse gas emissions of coal; the noted exception was a 2011 study by Howarth and others of Co ...

Tight Oil
Tight oil (also known as shale oil, shale-hosted oil or light tight oil, abbreviated LTO) is light crude oil contained in unconventional petroleum-bearing formations of low permeability, often shale or tight sandstone. Economic production from tight oil formations requires the same hydraulic fracturing and often uses the same horizontal well technology used in the production of shale gas. While sometimes called "shale oil", tight oil should not be confused with oil shale (shale rich in kerogen) or shale oil (oil produced from oil shales). Therefore, the International Energy Agency recommends using the term "light tight oil" for oil produced from shales or other very low permeability formations, while the World Energy Resources 2013 report by the World Energy Council uses the terms "tight oil" and "shale-hosted oil". In May 2013 the International Energy Agency in its ''Medium-Term Oil Market Report'' (MTOMR) said that the North American oil production surge led by unconventio ...

Unconventional (oil & Gas) Reservoir
Unconventional (oil & gas) reservoirs, or unconventional resources (resource plays) are accumulations where oil & gas phases are tightly bound to the rock fabric by strong capillary forces, requiring specialised measures for evaluation and extraction. Conventional reservoir Oil and gas are generated naturally at depths of around 4 or 5 kms below Earth’s surface. Being lighter than the water, which saturates rocks below the water table, the oil and gas percolate up through aquifer pathways towards Earth's surface (through time) by buoyancy. Some of the oil and gas percolate all the way to the surface as natural seepages, either on land or on the sea floor. The rest remain trapped underground where the oil and gas are prevented from reaching the surface by geological barriers, in a range of trap geometries. In this way, underground pockets of oil & gas accumulate by displacing water in porous rock, which, if permeable, are referred to as ''conventional reservoirs''. A ...

Source Rock
In petroleum geology, source rock is rock which has generated hydrocarbons or which could generate hydrocarbons. Source rocks are one of the necessary elements of a working petroleum system. They are organic-rich sediments that may have been deposited in a variety of environments including deep water marine, lacustrine and deltaic. Oil shale can be regarded as an organic-rich but immature source rock from which little or no oil has been generated and expelled. Subsurface source rock mapping methodologies make it possible to identify likely zones of petroleum occurrence in sedimentary basins as well as shale gas plays. Types of source rocks Source rocks are classified from the types of kerogen that they contain, which in turn governs the type of hydrocarbons that will be generated: * Type I source rocks are formed from algal remains deposited under anoxic conditions in deep lakes: they tend to generate waxy crude oils when submitted to thermal stress during deep burial. * Type ...
