They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.Biodegradation, Environmental: Elimination of ENVIRONMENTAL POLLUTANTS; PESTICIDES and other waste using living organisms, usually involving intervention of environmental or sanitation engineers.Bleaching Agents: Chemicals that are used to oxidize pigments and thus effect whitening.Methane: The simplest saturated hydrocarbon.

Before the 16th century it was ruled by independent emirs but was captured and controlled by the Portuguese 1508-1648. In 1741 it was recovered by a descendent of Yemen's imam. After its decline in the 19th century, it became virtually a political and economic dependency within the British Government of India, retaining close ties with Great Britain by treaty from 1939 to 1970 when it achieved autonomy. The name was recorded by Pliny in the 1st century A.D. as Omana, said to be derived from the founder of the state, Oman ben Ibrahim al-Khalil. (From Webster's New Geographical Dictionary, 1988, p890; Oman Embassy, Washington; Room, Brewer's Dictionary of Names, 1992, p391)Sulfur-Reducing Bacteria: A group of gram-negative, anaerobic bacteria that is able to oxidize acetate completely to carbon dioxide using elemental sulfur as the electron acceptor.Bioreactors: Tools or devices for generating products using the synthetic or chemical conversion capacity of a biological system.

They are characterized by: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls; (3) the presence of ether-linked lipids built from branched-chain subunits; and (4) their occurrence in unusual habitats. While archaea resemble bacteria in morphology and genomic organization, they resemble eukarya in their method of genomic replication. The domain contains at least four kingdoms: CRENARCHAEOTA; EURYARCHAEOTA; NANOARCHAEOTA; and KORARCHAEOTA.Phylogeny: The relationships of groups of organisms as reflected by their genetic makeup.Geologic Sediments: A mass of organic or inorganic solid fragmented material, or the solid fragment itself, that comes from the weathering of rock and is carried by, suspended in, or dropped by air, water, or ice. It refers also to a mass that is accumulated by any other natural agent and that forms in layers on the earth's surface, such as sand, gravel, silt, mud, fill, or loess.

Out of total 10 bcm intended for Europe, 1 bcm will go to Bulgaria and Greece and the rest will go to buyers in other countries, mainly Italy. The project will include two additional bridge-linked offshore gas platforms, undersea wells and an expansion of the gas plant at Sangachal Terminal, at an estimated cost of at least $10 billion.[9] The overall cost of Phase 2 expansion, including upstream and midstream stages (TANAP and TAP pipelines) is estimated to be around $45 billion. In December 2016, the Asian Development Bank approved a total of $1 billion in both public and private assistance to support the expansion of the Shah Deniz 2 field. The assistance was made up of a $500 million private sector loan to the Southern Gas Corridor Closed Joint Stock Company and a $500 million sovereign-counterguaranteed partial credit guarantee. This guarantee will back over $500 million in commercial loans from a consortium of banks to SCG.[10] According to the 2017 year-end results, Azerbaijani ...
The governance of the Alberta oil sands is focused on economic development, and has historically been dominated by the interests of two primary actors; government (federal and provincial) and industry. Canadian federalism forms the functions and roles of each level of government, in that constitutional power is split so that neither is superior to the other.[76] The Constitution Act, 1867, Section 109 ensures the province full ownership of the lands and resources within its borders. The province acts as the landowner and the federal government oversees jurisdiction over trade, commerce and taxation. There is a clear overlap, as resource management influences trade, and trade management influences resources.[77] As of the 1990s, both the federal and provincial government have been aligned, focusing on regulation, technology and the development of new export markets.[78] The majority of "ground-level" governance is carried out by a number of provincial institutions. Ottawa has avoided direct ...
Offshore", when used relative to hydrocarbons, refers to an oil, natural gas or condensate field that is under the sea, or to activities or operations carried out in relation to such a field. There are various types of platform used in the development of offshore oil and gas fields, and subsea facilities.[citation needed]. Offshore exploration is performed with floating drilling units. ...
The government celebrated twenty years of independence in September 1991 with the start of phase one of the North Field development project. The gas project, in a 6000 km² field off Qatar's northeast coast, is supervised by Bechtel based in the United States and by Technip in France. The project marks a major step in Qatar's switch from a reliance on oil to gas for most of its revenues. The North Field is the world's largest natural gas field, and its exploitation will place Qatar in the top ranks of the world's gas producers. Natural gas from other fields provides fuel for power generation and raw materials for fertilizers, petrochemicals, and steel plants. With the expected depletion of oil reserves by about 2023, planners hope natural gas from the North Field will provide a significant underpinning for the country's economic development. In the early 1970s, Qatar flared about 80% of the 16.8 hm³ of natural gas produced daily in association with crude oil liftings. In that decade, the ...
Discussions between the governments of Iran and Pakistan started in 1995.[5] A preliminary agreement was signed in 1995. This agreement foresaw construction of a pipeline from South Pars gas field to Karachi in Pakistan. Later Iran made a proposal to extend the pipeline from Pakistan into India. In February 1999, a preliminary agreement between Iran and India was signed.[6] In 2004 the project was revived after the UNDP's report Peace and Prosperity Gas Pipelines by Pakistani petroleum engineer, Gulfaraz Ahmed, was published in December 2003. The report highlighted benefits of the pipeline to Pakistan, India and Iran.[7] In February 2007, India and Pakistan agreed to pay Iran US$4.93 per million British thermal units (US$4.67/GJ) but some details relating to price adjustment remained open to further negotiation.[8] In April 2008, Iran expressed interest in the People's Republic of China's participation in the project.[9] In August 2010, Iran invited Bangladesh to join the project.[10] In 2009, ...
... Sdn Bhd was a state owned holding company based in Labuan, Malaysia. It was established in 1982 by the Government of Sabah for the downstream operations of Sabah natural gas resources. The company owned and operated a 660,000-tonne per year methanol plant, a 600,000-tonne per year sponge iron factory, and a 79 MW natural gas-fired power station, all commissioned in 1984 after the gas pipeline from the offshore gas fields became operational. The industries were supplied by natural gas from the Erb West and Samarang offshore fields. In the beginning of the 1990s, due to financial difficulties, the company was put for privatisation. In 1992, the methanol plant was sold to Petronas and operates today as Petronas Methanol (Labuan) Sdn Bhd. The power station was sold to Sabah Electricity. The sponge iron factory was bought by the affiliated companies of the today's Lion Group. The plant operates today as Antara Steel Mills Sdn Bhd. Malaysia portal Energy policy of Malaysia Lee, ...
The Athabasca oil sands deposit represents the second largest known deposit of oil in the world - after Saudi Arabia. There are estimated to be more than a trillion barrels of oil embedded in the sands, with an estimated 315 billion barrels (5.01×1010 m3) considered to be recoverable.[5] Production of synthetic crude oil from the tar sands is well under way - Alberta is producing about 1.3 million barrels (210,000 m3) of dirty oil per day.[6] That amount is expected to double or triple in the next few years, based on recent massive private investment in these projects. The environmental liabilities that result from the various steps in oil sands extraction and refining process include: i. Destruction of the boreal forest eco-system ii. Damage to the Athabasca watershed iii. Heavy consumption of natural gas iv. Creation of toxic tailings ponds v. Increased release of greenhouse gases i. Destruction of the boreal forest eco-system All of the oil sands leases slated for development are located in ...
... arises from the increasing airborne chemicals, matter and biological materials in the air. These factors cause harm to human health, the environment and to the economy. In the Canadian context, the main contributor of air pollution stems from burning fossil fuels for power and energy. Fossil fuels continue to be the main source of fuel for Canadians, even though the government is aware of the negative effects that it has on the environment and human health. Air pollution in Canada continues to be an issue due to the pressures with climate change, increased urbanization and continued reliance on vehicles as the primary source of transportation. A major contributor to the problem of Canadian air pollution are the Alberta Oil Sands. Though they are not closely related to major Canadian Metropolitan Areas, the quality of mostly rural Northern Alberta is poorer than areas of similar population densities in Canada. Toronto and other Canadian municipalities face environmental ...
Tailing ponds are areas of refused mining tailings where the waterborne refuse material is pumped into a pond to allow the sedimentation (meaning separation) of solids from the water. The pond is generally impounded with a dam, and known as tailings impoundments or tailings dams.[1] It was estimated in 2000 that there were about 3,500 active tailings impoundments in the world.[8] The ponded water is of some benefit as it minimizes fine tailings from being transported by wind into populated areas where the toxic chemicals could be potentially hazardous to human health; however, it is also harmful to the environment. Tailing ponds are often somewhat dangerous because they attract wildlife such as waterfowl or caribou as they appear to be a natural pond, but they can be highly toxic and harmful to the health of these animals. Tailings ponds are used to store the waste made from separating minerals from rocks, or the slurry produced from tar sands mining. Tailings are sometimes mixed with other ...
... is closely related to natural bitumen from oil sands. Petroleum geologists categorize bitumen from oil sands as 'extra-heavy oil' due to its density of less than 10° °API.[8] Bitumen is the heaviest, thickest form of petroleum.[9] According to the U.S. Geological Survey, bitumen is further distinguished as extra-heavy oil with a higher viscosity (i.e., resistance to flow): "Natural bitumen, also called tar sands or oil sands, shares the attributes of heavy oil but is yet more dense and viscous. Natural bitumen is oil having a viscosity greater than 10,000 cP."[8] "Natural bitumen (often called tar sands or oil sands) and heavy oil differ from light oils by their high viscosity (resistance to flow) at reservoir temperatures, high density (low API gravity), and significant contents of nitrogen, oxygen, and sulfur compounds and heavy-metal contaminants. They resemble the residuum from the refining of light oil. Most heavy oil is found at the margins of geologic basins and is ...
Many different strategies are used to provide this protection, including outright acquisition of the land by the trust. In other cases, the land will remain in private hands, but the trust will purchase a conservation easement on the property to prevent development, or purchase any mining, logging, drilling, or development rights on the land. Trusts also provide funding to assist like-minded private buyers or government organizations to purchase and protect the land forever.[citation needed]. As non-profit organizations, land trusts rely on donations, grants and public land acquisition programs for operating expenses and for acquiring land and easements. Donors often provide monetary support, but it is common for conservation-minded landowners to donate an easement on their land, or the land itself. Some land trusts also receive funds from government programs to acquire, protect, and manage land. Some trusts can afford to pay employees, but many others depend entirely on volunteers. According to ...
Though Stelmach pledged not to do anything to curb the development of the oilsands, he did promise to review royalty rates-the rates paid by oil companies for the privilege of extracting Alberta's oil. He also committed to reducing the proportion of bitumen that left Alberta to be upgraded out of province, likening the export of bitumen to "scraping off the top soil" from farmland.[44] Soon after becoming Premier, he commissioned the Alberta Royalty Review panel to make recommendations on the province's royalty regime; opposition politicians had accused the government of undercharging substantially. Stelmach rejected many of the panel's recommendations, and claimed to increase royalty rates by approximately 20% (25% less than recommended by the panel), however instead of an increase in royalties on oil and gas, Alberta collected $13.5 billion less from 2009 to 2014.[51] Just after the 2008 election, Stelmach's government announced a five-year royalty break worth $237 million per year to ...
After the discovery of a reservoir, a petroleum engineer will seek to build a better picture of the accumulation. In a simple textbook example of a uniform reservoir, the first stage is to conduct a seismic survey to determine the possible size of the trap. Appraisal wells can be used to determine the location of oil-water contact and with it the height of the oil bearing sands. Often coupled with seismic data, it is possible to estimate the volume of an oil-bearing reservoir. The next step is to use information from appraisal wells to estimate the porosity of the rock. The porosity, or the percentage of the total volume that contains fluids rather than solid rock, is 20-35% or less. It can give information on the actual capacity. Laboratory testing can determine the characteristics of the reservoir fluids, particularly the expansion factor of the oil, or how much the oil expands when brought from the high pressure and high temperature of the reservoir to a "stock tank" at the surface. With such ...
