82-552: The building was intended to be a landmark of the Songdo International Business District which was constructed on unused land along the waterfront near Incheon. It features 19 floors of class A office space , an observatory on the 65th-floor, a luxury hotel , serviced residences , and retail stores . The column-free floors include an office lobby at ground level with French limestone floors and Vermont slate stone walls. Like One World Trade Center ,

164-478: A 3,000,000-square-foot (280,000 m ) building in Chicago, at the time the largest building in the world. The time and motion study , pioneered in manufacturing by F. W. Taylor and later applied to the office environment by Frank and Lillian Gilbreth , led to the idea that managers needed to play an active role in directing the work of subordinates to increase the efficiency of the workplace. F.W. Taylor advocated

246-520: A fluid resembling petroleum, which when treated in the same way as the seep oil gave similar products. Young found that by slow distillation he could obtain several useful liquids from it, one of which he named "paraffine oil" because at low temperatures it congealed into a substance resembling paraffin wax. The production of these oils and solid paraffin wax from coal formed the subject of his patent dated October 17, 1850. In 1850, Young & Meldrum and Edward William Binney entered into partnership under

328-406: A future subway station. Floors 2 to 33 are occupied by several businesses, with Daewoo occupying levels 9 to 21. The 36th and 37th floors are allocated for banquets, restaurants, meeting rooms and other formal activities, while floors 38 to 64 features a residence hotel with 423 guest rooms, including a penthouse on the upper floor. In February 2010, the 65th-floor observatory temporarily opened to

410-515: A lot of concentration, or include many small meetings.

Support spaces in an office are typically used for secondary activities such as filing documents or taking breaks. There are twelve generic types of support spaces, each supporting different activities. Filing space : an open or enclosed support space for

574-512: A much shallower level. The Athabasca oil sands are one example of this. An alternative mechanism to the one described above was proposed by Russian scientists in the mid-1850s, the hypothesis of abiogenic petroleum origin (petroleum formed by inorganic means), but this is contradicted by geological and geochemical evidence. Abiogenic sources of oil have been found, but never in commercially profitable amounts. "The controversy isn't over whether abiogenic oil reserves exist," said Larry Nation of

656-649: A palace complex or a large temple. In the High Middle Ages (1000–1300), the medieval chancery acted as a sort of office, serving as the space where records and laws were stored and copied. With the growth of large, complex organizations in the 18th century, the first purpose-built office spaces were constructed. As the Industrial Revolution intensified in the 18th and 19th centuries, the industries of banking , rail , insurance , retail , petroleum , and telegraphy grew dramatically, requiring many clerks. As

738-476: A process known as catagenesis . Formation of petroleum occurs from hydrocarbon pyrolysis in a variety of mainly endothermic reactions at high temperatures or pressures, or both. These phases are described in detail below. In the absence of plentiful oxygen, aerobic bacteria were prevented from decaying the organic matter after it was buried under a layer of sediment or water. However, anaerobic bacteria were able to reduce sulfates and nitrates among

820-400: A result of the country's unique business culture. Japanese offices tend to follow open plan layouts in an 'island-style' arrangement, which promotes teamwork and top-down management. They also use uchi-awase (informal meetings) and ringi-sho (consensus systems) to encourage input on policies from as many groups throughout the office as possible. The main purpose of an office environment

902-433: A result, more office space was assigned to house their activities. The time-and-motion study , pioneered in manufacturing by F. W. Taylor (1856–1915), led to the "Modern Efficiency Desk" of 1915. Its flat top, with drawers below, was designed to allow managers an easy view of their workers. By the middle of the 20th century, it became apparent that an efficient office required additional control over privacy , and gradually

Waiting area : an open or semi-open support space where visitors can be received and wait for their appointment. Circulation space : support space which

1148-643: A significant amount of petroleum while drilling for lignite in Wietze , Germany. Wietze later provided about 80% of German consumption in the Wilhelminian Era. The production stopped in 1963, but Wietze has hosted a Petroleum Museum since 1970. Oil sands have been mined since the 18th century. In Wietze in lower Saxony, natural asphalt/bitumen has been explored since the 18th century. Both in Pechelbronn as in Wietze,

1230-474: A simple solution and provide all of the former types of space. Workspaces in an office are typically used for conventional office activities such as reading, writing, and computer work. There are nine generic types of workspaces, each supporting different activities. Open office : an open workspace for more than ten people; suitable for activities that demand frequent communication or routine activities that need relatively little concentration. Team space :

1312-574: A source of internal and inter-state conflict, leading to both state-led wars and other resource conflicts . Production of petroleum is estimated to reach peak oil before 2035 as global economies lower dependencies on petroleum as part of climate change mitigation and a transition towards renewable energy and electrification . The word petroleum comes from Medieval Latin petroleum (literally 'rock oil'), which comes from Latin petra 'rock' (from Greek pétra πέτρα ) and oleum 'oil' (from Greek élaion ἔλαιον ). The origin of

1394-411: A variety of liquid, gaseous, and solid components. Lighter hydrocarbons are the gases methane , ethane , propane and butane . Otherwise, the bulk of the liquid and solids are largely heavier organic compounds, often hydrocarbons (C and H only). The proportion of light hydrocarbons in the petroleum mixture varies among oil fields . An oil well produces predominantly crude oil. Because the pressure

1476-520: A visit to Fort Duquesne in 1750. Early British explorers to Myanmar documented a flourishing oil extraction industry based in Yenangyaung that, in 1795, had hundreds of hand-dug wells under production. Merkwiller-Pechelbronn is said to be the first European site where petroleum has been explored and used. The still active Erdpechquelle, a spring where petroleum appears mixed with water has been used since 1498, notably for medical purposes. There

1558-547: A year before Drake's Pennsylvania operation and could be argued to be the first commercial oil well in North America. The discovery at Oil Springs touched off an oil boom which brought hundreds of speculators and workers to the area. Advances in drilling continued into 1862 when local driller Shaw reached a depth of 62 metres using the spring-pole drilling method. On January 16, 1862, after an explosion of natural gas , Canada's first oil gusher came into production, shooting into

1640-439: Is also an architectural and design phenomenon, including small offices, such as a bench in the corner of a small business or a room in someone's home (see small office/home office ), entire floors of buildings, and massive buildings dedicated entirely to one company. In modern terms, an office is usually the location where white-collar workers carry out their functions. In classical antiquity , offices were often part of

1722-487: Is called diagenesis , a word that means a transformation of materials by dissolution and recombination of their constituents. Kerogen formation continued to a depth of about 1 km from the Earth's surface where temperatures may reach around 50 °C . Kerogen formation represents a halfway point between organic matter and fossil fuels : kerogen can be exposed to oxygen, oxidize and thus be lost, or it could be buried deeper inside

1804-717: Is considered a sticky, black, tar-like form of crude oil which is so thick and heavy that it must be heated or diluted before it will flow. Venezuela also has large amounts of oil in the Orinoco oil sands , although the hydrocarbons trapped in them are more fluid than in Canada and are usually called extra heavy oil . These oil sands resources are called unconventional oil to distinguish them from oil which can be extracted using traditional oil well methods. Between them, Canada and Venezuela contain an estimated 3.6 trillion barrels (570 × 10 ^  m ) of bitumen and extra-heavy oil, about twice

1886-738: Is done after a study of the relevant structural geology , analysis of the sedimentary basin , and characterization of the petroleum reservoir . There are also unconventional reserves such as oil sands and oil shale which are recovered by other means such as fracking . Once extracted, oil is refined and separated, most easily by distillation , into innumerable products for direct use or use in manufacturing. Products include fuels such as gasoline (petrol), diesel , kerosene and jet fuel ; asphalt and lubricants ; chemical reagents used to make plastics ; solvents , textiles , refrigerants , paint , synthetic rubber , fertilizers , pesticides , pharmaceuticals , and thousands of others. Petroleum

1968-473: Is lower at the surface than underground, some of the gas will come out of solution and be recovered (or burned) as associated gas or solution gas . A gas well produces predominantly natural gas . However, because the underground temperature is higher than at the surface, the gas may contain heavier hydrocarbons such as pentane, hexane , and heptane (" natural-gas condensate ", often shortened to condensate. ) Condensate resembles gasoline in appearance and

2050-737: Is now called the Drake Well in Cherrytree Township, Pennsylvania .There also was a company associated with it, and it sparked a major oil drilling boom. The first commercial oil well in Canada became operational in 1858 at Oil Springs, Ontario (then Canada West ). Businessman James Miller Williams dug several wells between 1855 and 1858 before discovering a rich reserve of oil four metres below ground. Williams extracted 1.5 million litres of crude oil by 1860, refining much of it into kerosene lamp oil. Williams's well became commercially viable

2132-706: Is required for circulation on office floors, linking all major functions. Lactation rooms are also support spaces that are legally mandatory for companies in the United States, as of the 2010 Patient Protection and Affordable Care Act. Petroleum Petroleum is a naturally occurring yellowish-black liquid mixture. It consists mainly of hydrocarbons , and is found in geological formations . The term petroleum refers both to naturally occurring unprocessed crude oil, as well as to petroleum products that consist of refined crude oil. Conventional reserves of petroleum are primarily recovered by drilling , which

2214-451: Is similar in composition to some volatile light crude oils . The hydrocarbons in crude oil are mostly alkanes , cycloalkanes and various aromatic hydrocarbons , while the other organic compounds contain nitrogen , oxygen , and sulfur , and traces of metals such as iron, nickel, copper and vanadium . Many oil reservoirs contain live bacteria. The exact molecular composition of crude oil varies widely from formation to formation but

2296-513: Is to support its occupants in performing their jobs—preferably at minimum cost and with maximum satisfaction. Different people performing different tasks will require different office spaces, or spaces that can handle a variety of uses. To aid decision-making in workplace and office design, one can distinguish three different types of office spaces: workspaces, meeting spaces, and support spaces. For new or developing businesses, remote satellite offices and project rooms, or serviced offices , can provide

2378-473: Is used in manufacturing a vast variety of materials essential for modern life, and it is estimated that the world consumes about 100 million barrels (16 million cubic metres ) each day. Petroleum production played a key role in industrialization and economic development. Some countries, known as petrostates , gained significant economic and international power over their control of oil production and trade. Petroleum exploitation can be damaging to

2460-670: The Earth's crust and be subjected to conditions which allow it to slowly transform into fossil fuels like petroleum. The latter happened through catagenesis in which the reactions were mostly radical rearrangements of kerogen. These reactions took thousands to millions of years and no external reactants were involved. Due to the radical nature of these reactions, kerogen reacted towards two classes of products: those with low H/C ratio ( anthracene or products similar to it) and those with high H/C ratio ( methane or products similar to it); i.e., carbon-rich or hydrogen-rich products. Because catagenesis

2542-484: The Orinoco Belt . While significant volumes of oil are extracted from oil sands, particularly in Canada, logistical and technical hurdles remain, as oil extraction requires large amounts of heat and water, making its net energy content quite low relative to conventional crude oil. Thus, Canada's oil sands are not expected to provide more than a few million barrels per day in the foreseeable future. Petroleum consists of

2624-724: The Soviet Union in total output. In 1973 , Saudi Arabia and other Arab nations imposed an oil embargo against the United States, United Kingdom, Japan and other Western nations which supported Israel in the Yom Kippur War of October 1973. The embargo caused an oil crisis . This was followed by the 1979 oil crisis , which was caused by a drop in oil production in the wake of the Iranian Revolution and caused oil prices to more than double. The two oil price shocks had many short- and long-term effects on global politics and

2706-533: The United States , but is responsible for only one percent of electricity generation. Petroleum's worth as a portable, dense energy source powering the vast majority of vehicles and as the base of many industrial chemicals makes it one of the world's most important commodities . The top three oil-producing countries as of 2018 are the United States, Russia , and Saudi Arabia . In 2018, due in part to developments in hydraulic fracturing and horizontal drilling ,

2788-455: The actinomycetales order of bacteria also produced antibiotic compounds (e.g., streptomycin ). Thus the action of anaerobic bacteria ceased at about 10 m below the water or sediment. The mixture at this depth contained fulvic acids, unreacted and partially reacted fats and waxes, slightly modified lignin , resins and other hydrocarbons. As more layers of organic matter settled into the sea or lake bed, intense heat and pressure built up in

2870-494: The cubicle system evolved. The word "office" stems from the Latin " officium " and its equivalents in various Romance languages . An officium was not necessarily a place, but often referred instead to human staff members of an organization, or even the abstract notion of a formal position like a magistrate. The elaborate Roman bureaucracy would not be equaled for centuries in the West after

2952-567: The 12th century. It has also been present in Romania since the 13th century, being recorded as păcură. Sophisticated oil pits, 4.5 to 6 metres (15 to 20 ft) deep, were dug by the Seneca people and other Iroquois in Western Pennsylvania as early as 1415–1450. The French General Louis-Joseph de Montcalm encountered Seneca using petroleum for ceremonial fires and as a healing lotion during

3034-711: The 18th century to suit the needs of large and growing organizations such as the Royal Navy and the East India Company . The Old Admiralty ( Ripley Building ) was built in 1726 and was the first purpose-built office building in Great Britain. As well as offices, the building housed a board room and apartments for the Lords of the Admiralty. In the 1770s, many scattered offices for the Royal Navy were gathered into Somerset House ,

3116-494: The American Association of Petroleum Geologists. "The controversy is over how much they contribute to Earth's overall reserves and how much time and effort geologists should devote to seeking them out." Three conditions must be present for oil reservoirs to form: The reactions that produce oil and natural gas are often modeled as first order breakdown reactions, where hydrocarbons are broken down to oil and natural gas by

3198-455: The Earth's surface. Unusual magma intrusions, however, could have created greater localized heating. Geologists often refer to the temperature range in which oil forms as an "oil window" . Below the minimum temperature oil remains trapped in the form of kerogen. Above the maximum temperature the oil is converted to natural gas through the process of thermal cracking . Sometimes, oil formed at extreme depths may migrate and become trapped at

3280-572: The Soviet Union included the goal to capture the Baku oilfields , as it would provide much-needed oil supplies for the German military which was suffering from blockades. Oil exploration in North America during the early 20th century later led to the U.S. becoming the leading producer by mid-century. As petroleum production in the U.S. peaked during the 1960s, the United States was surpassed by Saudi Arabia and

3362-561: The United States became the world's largest producer. About 80 percent of the world's readily accessible reserves are located in the Middle East , with 62.5 percent coming from the Arab five: Saudi Arabia , United Arab Emirates , Iraq , Qatar , and Kuwait . A large portion of the world's total oil exists as unconventional sources, such as bitumen in Athabasca oil sands and extra heavy oil in

3444-609: The air at a recorded rate of 480 cubic metres (3,000 bbl) per day. By the end of the 19th century the Russian Empire, particularly the Branobel company in Azerbaijan , had taken the lead in production. Access to oil was and still is a major factor in several military conflicts of the 20th century, including World War II , during which oil facilities were a major strategic asset and were extensively bombed . The German invasion of

3526-539: The area around modern Baku , Azerbaijan . These fields were described by the Persian geographer Abu Bakr al-Razi in the 10th century, and by Marco Polo in the 13th century, who described the output of those wells as hundreds of shiploads. Arab and Persian chemists also distilled crude oil to produce flammable products for military purposes. Through Islamic Spain , distillation became available in Western Europe by

3608-542: The average consumption rate of a typical office building. In addition, a graywater collection system is used to flush wastewater while collected stormwater is stored and reused, reducing water consumption by more than 50 percent. The building is next to Songdo Convensia , the Riverstone shopping center , and the Sheraton Incheon Hotel . It has an extensive parking station next door, and will have pedestrian access to

3690-428: The central office each day. As the Industrial Revolution intensified in the 18th and 19th centuries, the industries of banking , rail , insurance , retail , petroleum , and telegraphy dramatically grew in size and complexity. Increasingly large number of clerks were needed to handle order processing, accounting, and document filing, and these clerks needed to be housed in increasingly specialized spaces. Most of

3772-474: The coal industry dominated the petroleum technologies. Chemist James Young in 1847 noticed a natural petroleum seepage in the coal mine at riddings Alfreton , Derbyshire from which he distilled a light thin oil suitable for use as lamp oil, at the same time obtaining a more viscous oil suitable for lubricating machinery. In 1848, Young set up a small business refining crude oil. Young eventually succeeded, by distilling cannel coal at low heat, in creating

3854-418: The desks of the era were top-heavy and had a cubicle-like appearance, with paper storage bins extending above the desk-work area, offering workers some degree of privacy. The relatively high price of land in the central core of cities led to the first multi-story buildings, which were limited to about 10 stories until the use of iron and steel allowed for higher structures. The first purpose-built office block

3936-564: The earliest Chinese writings, cites that oil in its raw state, without refining, was first discovered, extracted, and used in China in the first century BCE. In addition, the Chinese were the first to record the use of petroleum as fuel as early as the fourth century BCE. By 347 CE, oil was produced from bamboo-drilled wells in China. In the 7th century, petroleum was among the essential ingredients for Greek fire , an incendiary projectile weapon that

4018-469: The environment and human health. Extraction , refining and burning of petroleum fuels all release large quantities of greenhouse gases , so petroleum is one of the major contributors to climate change . Other negative environmental effects include direct releases, such as oil spills , as well as air and water pollution at almost all stages of use. These environmental effects have direct and indirect health consequences for humans. Oil has also been

4100-401: The existence of such "offices". These rooms are sometimes called "libraries" by some archaeologists because of scrolls' association with literature. They were, however, closer to modern offices because the scrolls were meant for record-keeping and other management functions, not for poetry or works of fiction. The High Middle Ages (1000–1300) saw the rise of the medieval chancery , which was

4182-425: The fact that it happened at relatively low temperatures (when compared to commercial pyrolysis plants) of 60 to several hundred °C. Pyrolysis was possible because of the long reaction times involved. Heat for catagenesis came from the decomposition of radioactive materials of the crust, especially K , Th , U and U . The heat varied with geothermal gradient and was typically 10–30 °C per km of depth from

4264-471: The fall of Rome , with areas partially reverting to illiteracy. Further east, the Byzantine Empire and varying Islamic caliphates preserved a more sophisticated administrative culture. Offices in classical antiquity were often part of a palace complex or a large temple. There was often a room where scrolls were kept and scribes did their work. Ancient texts mentioning the work of scribes allude to

4346-534: The first block purpose-built for office work. The East India House was built in 1729 on Leadenhall Street as the headquarters from which the East India Company administered its Indian colonial possessions . The Company developed a very complex bureaucracy for the task, necessitating thousands of office employees to process the required paperwork. The Company recognized the benefits of centralized administration and required that all workers sign in and out at

4428-794: The global economy. They led to sustained reductions in demand as a result of substitution to other fuels, especially coal and nuclear, and improvements in energy efficiency , facilitated by government policies. High oil prices also induced investment in oil production by non-OPEC countries, including Prudhoe Bay in Alaska, the North Sea offshore fields of the United Kingdom and Norway, the Cantarell offshore field of Mexico, and oil sands in Canada. About 90 percent of vehicular fuel needs are met by oil. Petroleum also makes up 40 percent of total energy consumption in

4510-408: The heavier end of the range, paraffin wax is an alkane with approximately 25 carbon atoms, while asphalt has 35 and up, although these are usually cracked in modern refineries into more valuable products. The lightest fraction, the so-called petroleum gases are subjected to diverse processing depending on cost. These gases are either flared off , sold as liquefied petroleum gas , or used to power

4592-559: The invention of the printing press and its wider distribution, there was often no clear cultural distinction between a private office and a private library ; books were both read and written at the same desk or table , as were personal and professional accounts and letters. During the 13th century, the English word "office" first began to appear when referring to a position involving specific professional duties (for example, "the office of the....") Geoffrey Chaucer appears to have first used

4674-638: The invention of the modern kerosene lamp (1853), the introduction of the first modern street lamp in Europe (1853), and the construction of the world's first modern oil "mine" (1854). at Bóbrka , near Krosno (still operational as of 2020). The demand for petroleum as a fuel for lighting in North America and around the world quickly grew. The first oil well in the Americas was drilled in 1859 by Edwin Drake at what

4756-446: The large number of co-eluted hydrocarbons within oil, many cannot be resolved by traditional gas chromatography. This unresolved complex mixture (UCM) of hydrocarbons is particularly apparent when analysing weathered oils and extracts from tissues of organisms exposed to oil. Crude oil varies greatly in appearance depending on its composition. It is usually black or dark brown (although it may be yellowish, reddish, or even greenish). In

4838-420: The latter is an earlier usage, as "office" originally referred to the location of one's duty. In its adjective form, the term "office" may refer to business -related tasks. In law , a company or organization has offices in any place where it has an official presence, even if that presence consists of a storage silo , for example, instead of a more traditional establishment with a desk and chair . An office

4920-411: The lower regions. As a consequence, compounds of this mixture began to combine in poorly understood ways to kerogen . Combination happened in a similar fashion as phenol and formaldehyde molecules react to urea-formaldehyde resins, but kerogen formation occurred in a more complex manner due to a bigger variety of reactants. The total process of kerogen formation from the beginning of anaerobic decay

5002-899: The matter to H 2 S and N 2 respectively by using the matter as a source for other reactants. Due to such anaerobic bacteria, at first, this matter began to break apart mostly via hydrolysis : polysaccharides and proteins were hydrolyzed to simple sugars and amino acids respectively. These were further anaerobically oxidized at an accelerated rate by the enzymes of the bacteria: e.g., amino acids went through oxidative deamination to imino acids , which in turn reacted further to ammonia and α-keto acids . Monosaccharides in turn ultimately decayed to CO 2 and methane . The anaerobic decay products of amino acids, monosaccharides, phenols and aldehydes combined into fulvic acids . Fats and waxes were not extensively hydrolyzed under these mild conditions. Some phenolic compounds produced from previous reactions worked as bactericides and

5084-637: The midpoint of the 20th century, it became apparent that an efficient office required more privacy in order to combat tedium, increase productivity, and encourage creativity. In 1964, the Herman Miller (office equipment) company contracted Robert Propst , a prolific industrial designer. Propst came up with the concept of the Action Office , which later evolved into the cubicle office furniture system. Offices in Japan have developed unique characteristics partly as

5166-659: The place where most government letters were written and laws were copied within a kingdom. The rooms of the chancery often had walls full of pigeonholes, constructed to hold rolled-up pieces of parchment for safekeeping or ready reference. This kind of structure was a precursor to the modern bookshelf. The introduction of the printing press during the Renaissance did not impact the setup and function of these government offices significantly. Medieval paintings and tapestries often show people in their private offices handling record-keeping books or writing on scrolls of parchment . Before

5248-556: The proportion of chemical elements varies over fairly narrow limits as follows: Four different types of hydrocarbon appear in crude oil. The relative percentage of each varies from oil to oil, determining the properties of each oil. The alkanes from pentane (C 5 H 12 ) to octane (C 8 H 18 ) are refined into gasoline, the ones from nonane (C 9 H 20 ) to hexadecane (C 16 H 34 ) into diesel fuel , kerosene and jet fuel . Alkanes with more than 16 carbon atoms can be refined into fuel oil and lubricating oil . At

5330-454: The public for the G-20 major economies meeting of finance ministers. Class A office space An office is a space where the employees of an organization perform administrative work in order to support and realize the various goals of the organization. The word "office" may also denote a position within an organization with specific duties attached to it (see officer or official );

5412-644: The refinery's own burners. During the winter, butane (C 4 H 10 ), is blended into the gasoline pool at high rates, because its high vapour pressure assists with cold starts. The aromatic hydrocarbons are unsaturated hydrocarbons that have one or more benzene rings . They tend to burn with a sooty flame, and many have a sweet aroma. Some are carcinogenic . These different components are separated by fractional distillation at an oil refinery to produce gasoline, jet fuel, kerosene, and other hydrocarbon fractions. The components in an oil sample can be determined by gas chromatography and mass spectrometry . Due to

5494-412: The reservoir it is usually found in association with natural gas, which being lighter forms a "gas cap" over the petroleum, and saline water which, being heavier than most forms of crude oil, generally sinks beneath it. Crude oil may also be found in a semi-solid form mixed with sand and water, as in the Athabasca oil sands in Canada, where it is usually referred to as crude bitumen . In Canada, bitumen

5576-509: The same time the world's first, small, oil refinery was opened at Jasło in Poland (then Austria), with a larger one opened at Ploiești in Romania shortly after. Romania (then being a vassal of the Ottoman empire) is the first country in the world to have had its annual crude oil output officially recorded in international statistics: 275 tonnes for 1857. In 1858, Georg Christian Konrad Hunäus found

5658-518: The second half of the 19th century, the term became commonly known for the liquid form of hydrocarbons. Petroleum, in one form or another, has been used since ancient times. More than 4300 years ago, bitumen was mentioned when the Sumerians used it to make boats. A tablet of the legend of the birth of Sargon of Akkad mentions a basket which was closed by straw and bitumen. More than 4000 years ago, according to Herodotus and Diodorus Siculus , asphalt

After that, the term was used in numerous manuscripts and books, such as in the treatise De Natura Fossilium , published in 1546 by the German mineralogist Georg Bauer , also known as Georgius Agricola. After the advent of the oil industry, during

5904-528: The title of E.W. Binney & Co. at Bathgate in West Lothian and E. Meldrum & Co. at Glasgow; their works at Bathgate were completed in 1851 and became the first truly commercial oil-works in the world with the first modern oil refinery. The world's first oil refinery was built in 1856 by Ignacy Łukasiewicz in Austria. His achievements also included the discovery of how to distill kerosene from seep oil,

5986-452: The tower features a faceted glass facade that gently tapers from a square base but transitions to a triangular rooftop. The offices, apartments and a hotel each have their own entrance lobby. The facade is made of high-performance glazed glass with exterior shading devices which allows the structure to regulate internal temperatures. The tower also features low-flow plumbing fixtures allowing reduced water usage by more than 20 percent compared to

6068-580: The use of large, open floor plans and desks that faced supervisors. As a result, in 1915, the Equitable Life Insurance Company in New York City introduced the "Modern Efficiency Desk" with a flat top and drawers below, designed to allow managers an easy view of the workers. This led to a demand for large square footage per floor in buildings, and a return to the open spaces that were seen in pre–industrial revolution buildings. However, by

6150-468: The volume of the world's reserves of conventional oil. Petroleum is a fossil fuel derived from fossilized organic materials , such as zooplankton and algae . Vast amounts of these remains settled to sea or lake bottoms where they were covered in stagnant water (water with no dissolved oxygen ) or sediments such as mud and silt faster than they could decompose aerobically . Approximately 1 m below this sediment, water oxygen concentration

6232-700: The word in 1395 to mean a place where business is transacted in The Canterbury Tales . As mercantilism became the dominant economic theory of the Renaissance , merchants tended to conduct their business in buildings that also sometimes housed people doing retail sales, warehousing, and clerical work. During the 15th century, the population density in many cities reached a point where merchants began to use stand-alone buildings to conduct their business. A distinction began to develop between religious, administrative/military, and commercial uses for buildings. The first purpose-built office spaces were constructed in

6314-612: Was activity in various parts of the world in the mid-19th century. A group directed by Major Alexeyev of the Bakinskii Corps of Mining Engineers hand-drilled a well in the Baku region of Bibi-Heybat in 1846. There were engine-drilled wells in West Virginia in the same year as Drake's well. An early commercial well was hand dug in Poland in 1853, and another in nearby Romania in 1857. At around

6396-414: Was closed off from external reactants, the resulting composition of the fuel mixture was dependent on the composition of the kerogen via reaction stoichiometry . Three types of kerogen exist: type I (algal), II (liptinic) and III (humic), which were formed mainly from algae , plankton and woody plants (this term includes trees , shrubs and lianas ) respectively. Catagenesis was pyrolytic despite

6478-423: Was low, below 0.1 mg/L, and anoxic conditions existed. Temperatures also remained constant. As further layers settled into the sea or lake bed, intense heat and pressure built up in the lower regions. This process caused the organic matter to change, first into a waxy material known as kerogen , found in various oil shales around the world, and then with more heat into liquid and gaseous hydrocarbons via

6560-526: Was the Brunswick Building, built in Liverpool in 1841. The invention of the safety elevator in 1852 by Elisha Otis enabled the rapid upward escalation of buildings. By the end of the 19th century, larger office buildings frequently contained large glass atriums to allow light into the complex and improve air circulation. By 1906, Sears , Roebuck, and Co. had opened their headquarters operation in

6642-475: Was used by Byzantine Greeks against Arab ships, which were then attacking Constantinople . Crude oil was also distilled by Persian chemists , with clear descriptions given in Arabic handbooks such as those of Abu Bakr al-Razi (Rhazes). The streets of Baghdad were paved with tar , derived from petroleum that became accessible from natural fields in the region. In the 9th century, oil fields were exploited in

6724-539: Was used in the construction of the walls and towers of Babylon ; there were oil pits near Ardericca and Babylon, and a pitch spring on Zakynthos . Great quantities of it were found on the banks of the river Issus , one of the tributaries of the Euphrates . Ancient Persian tablets indicate the medicinal and lighting uses of petroleum in the upper levels of their society. The use of petroleum in ancient China dates back to more than 2000 years ago.
