98-590: The Moomba Adelaide Pipeline System is a natural gas pipeline delivering gas from the Cooper Basin gas wells near Moomba to Adelaide , with spur pipelines to Angaston and Whyalla . It can also receive gas from Southeastern Queensland through the QSN Link pipeline owned by APA Group . The pipeline was developed by the Government of South Australia and commenced operation on 28 November 1969. It

196-423: A "supply chain". At the end of the supply chain, materials and finished products only flow there because of the customer behaviour at the end of the chain; academics Alan Harrison and Janet Godsell argue that "supply chain processes should be coordinated in order to focus on end customer buying behaviour", and look for "customer responsiveness" as an indicator confirming that materials are able to flow "through

294-588: A bank, for example, may play a supporting role in certain supply chains, but acts as either the customer or the nearest supplier to the customer in the supply chain for security printing . Brown et al. refer to supply chains as either "loosely coupled" or "tightly coupled": Cutting-edge companies are swapping their tightly coupled processes for loosely coupled ones, making themselves not only more flexible but also more profitable . These ideas refer to two polar models of collaboration: tightly coupled, or "hard-wired", also known as "linked", collaboration represents

392-440: A close relationship between a buyer and supplier within the chain, whereas a loosely-coupled link relates to low interdependency between buyer and seller and therefore greater flexibility. The Chartered Institute of Procurement & Supply 's professional guidance suggests that the aim of a tightly coupled relationship is to reduce inventory and avoid stock-outs . There are a variety of supply-chain models, which address both

490-409: A company's decision-making on the number of suppliers it will engage with for each product or service as an important aspect of the design of a supply chain. Determining the number of suppliers logically precedes an RFP process for determining which suppliers will form part of the supply chain. Morgan refers to an "n + 1 rule" example in the business practice of IT component supplier Intel , whereby

588-565: A company. Starting in the 1990s, several companies chose to outsource the logistics aspect of supply-chain management by partnering with a third-party logistics provider (3PL). Companies also outsource production to contract manufacturers. Technology companies have risen to meet the demand to help manage these complex systems. Cloud-based SCM technologies are at the forefront of next-generation supply chains due to their impact on optimization of time, resources, and inventory visibility. Cloud technologies facilitate work being processed offline from

686-481: A density 0.5539 times that of air (0.678 kg per standard cubic meter). In the early 1800s, natural gas became known as "natural" to distinguish it from the dominant gas fuel at the time, coal gas . Unlike coal gas, which is manufactured by heating coal, natural gas can be extracted from the ground in its native gaseous form. When the use of natural gas overtook the use of coal gas in English speaking countries in

784-405: A fundamentally new system. This leads to a panarchical interpretation of a supply chain, embedding it into a system of systems , allowing to analyze the interactions of the supply chain with systems that operate at other levels (e.g. society, political economy, planet Earth). For example, these three components of resilience can be identified in relation to the 2021 Suez Canal obstruction , when

882-438: A global map of the organization's supply network. In the 1980s, the term supply-chain management (SCM) was developed to express the need to integrate the key business processes, from end user through original suppliers. Original suppliers are those that provide products, services, and information that add value for customers and other stakeholders. The basic idea behind SCM is that companies and corporations involve themselves in

980-484: A major source of natural gas in the United States and Canada. Because of increased shale gas production the United States was in 2014 the number one natural gas producer in the world. The production of shale gas in the United States has been described as a "shale gas revolution" and as "one of the landmark events in the 21st century." Following the increased production in the United States, shale gas exploration

1078-405: A mobile app which solves the common issue of inventory residing in areas with no online coverage or connectivity. Supply chain managers are under constant scrutiny to secure the best pricing for their resources, which becomes a difficult task when faced with the inherent lack of transparency. Cost benchmarking helps to identify competitive pricing within the industry but benchmarking across

1176-422: A product design is completed, it drives the structure of the supply chain, limiting the flexibility of engineers to generate and evaluate different (and potentially more cost-effective) supply-chain alternatives. Design for Supply Chain is described as a process that aims to drastically reduce the product life cycle costs ... improve product quality, improve efficiency and improve profitability for all partners in

1274-440: A range of supply chain performance factors has been recommended as best practice. The SCOR model contains more than 150 key indicators which measure the performance of supply chain operations: see also Supply chain operations reference#Performance measurements . Debra Hofman has noted that "measuring supply chain performance is not a new practice. Most companies today measure at least some aspect of their supply chain and understand

1372-487: A sequence of supply chain processes in order to meet end customer buying behaviour". Many of the exchanges encountered in the supply chain take place between varied companies that seek to maximize their revenue within their sphere of interest but may have little or no knowledge or interest in the remaining players in the supply chain. More recently, the loosely coupled, self-organizing network of businesses who cooperate in providing product and service offerings has been called

1470-488: A ship blocked the canal for several days. Persistence means to "bounce back"; in our example it is about removing the ship as quickly as possible to allow "normal" operations. Adaptation means to accept that the system has reached a "new normal" state and to act accordingly; here, this can be implemented by redirecting ships around the African cape or use alternative modes of transport. Finally, transformation means to question

1568-515: A supply chain by exchanging information about market demand , distribution capacity and production capabilities. Keith Oliver , a consultant at Booz Allen Hamilton , is credited with the term's invention after using it in an interview for the Financial Times in 1982. The term was used earlier by Alizamir et al. in 1981, and Burns and Sivazlian in 1978. If all relevant information is accessible to any relevant company, every company in

1666-585: A supply chain seeks to match demand with supply and do so with minimal inventory . Various aspects of optimizing the supply chain include liaising with suppliers to eliminate bottlenecks; sourcing strategically to strike a balance between lowest material cost and transportation , implementing just-in-time techniques to optimize manufacturing flow; maintaining the right mix and location of factories and warehouses to serve customer markets; and using location allocation, vehicle routing analysis, dynamic programming , and traditional logistics optimization to maximize

1764-507: A supply chain, such as wholesale and retail determine their break-even point by considering transaction costs , relative to market price. Additionally, there are financial costs associated with all the stages of a supply chain model. The Global Supply Chain Forum has introduced an alternative supply chain model. This framework is built on eight key business processes that are both cross-functional and cross-firm in nature. Each process

1862-542: A synthetic crude that can be further refined into finished products, while MTG can produce synthetic gasoline from natural gas. STG+ can produce drop-in gasoline, diesel, jet fuel and aromatic chemicals directly from natural gas via a single-loop process. In 2011, Royal Dutch Shell's 140,000 barrels (22,000 m ) per day F–T plant went into operation in Qatar . Natural gas can be "associated" (found in oil fields ), or "non-associated" (isolated in natural gas fields ), and

1960-482: A year (often seasonally). The supply chain for clothing often requires constant analysis of new fashion trends to manage the quantity needed for various markets. Supply chain security has become particularly important in recent years. As a result, supply chains are often subject to global and local regulations. In the United States, several major regulations emerged in 2010 that have had a lasting impact on how global supply chains operate. These new regulations include

2058-542: Is 38.7 kilometres (24.0 mi) of 219 millimetres (8.6 in) diameter. There are also several loops at the southern end. The Reeves Plains Power Station was in 2017 proposed to be constructed adjacent to the pipeline and draw gas directly from it. However, support had not been obtained by March 2019, when the project was one of 12 projects shortlisted in the Government of Australia 's Underwriting New Generation Investments program. Natural gas Natural gas (also called fossil gas, methane gas , or simply gas )

2156-493: Is a flammable gaseous fuel made by the destructive distillation of coal . It contains a variety of calorific gases including hydrogen , carbon monoxide , methane , and other volatile hydrocarbons , together with small quantities of non-calorific gases such as carbon dioxide and nitrogen , and was used in a similar way to natural gas. This is a historical technology and is not usually economically competitive with other sources of fuel gas today. Most town "gashouses" located in

2254-517: Is a high-level, industry-neutral enterprise process model that allows organizations to see their business processes from a cross-industry viewpoint. The PCF was developed by APQC and its member organizations as an open standard to facilitate improvement through process management and benchmarking, regardless of industry, size, or geography. The PCF organizes operating and management processes into 12 enterprise-level categories, including process groups, and over 1,000 processes and associated activities. In

2352-421: Is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) in addition to various smaller amounts of other higher alkanes . Traces of carbon dioxide , nitrogen , hydrogen sulfide , and helium are also usually present. Methane is colorless and odorless, and the second largest greenhouse gas contributor to global climate change after carbon dioxide. Because natural gas

2450-458: Is a schematic block flow diagram of a typical natural gas processing plant. It shows the various unit processes used to convert raw natural gas into sales gas pipelined to the end user markets. The block flow diagram also shows how processing of the raw natural gas yields byproduct sulfur, byproduct ethane, and natural gas liquids (NGL) propane, butanes and natural gasoline (denoted as pentanes +). As of mid-2020, natural gas production in

2548-399: Is also found in coal beds (as coalbed methane ). It sometimes contains a significant amount of ethane , propane , butane , and pentane —heavier hydrocarbons removed for commercial use prior to the methane being sold as a consumer fuel or chemical plant feedstock. Non-hydrocarbons such as carbon dioxide , nitrogen , helium (rarely), and hydrogen sulfide must also be removed before

2646-628: Is beginning in countries such as Poland, China, and South Africa. Chinese geologists have identified the Sichuan Basin as a promising target for shale gas drilling, because of the similarity of shales to those that have proven productive in the United States. Production from the Wei-201 well is between 10,000 and 20,000 m per day. In late 2020, China National Petroleum Corporation claimed daily production of 20 million cubic meters of gas from its Changning-Weiyuan demonstration zone. Town gas

2744-537: Is estimated to have 51,000 cubic kilometers (12,000 cu mi) of natural gas and 50 billion barrels (7.9 billion cubic meters) of natural gas condensates . Because natural gas is not a pure product, as the reservoir pressure drops when non-associated gas is extracted from a field under supercritical (pressure/temperature) conditions, the higher molecular weight components may partially condense upon isothermic depressurizing—an effect called retrograde condensation . The liquid thus formed may get trapped as

2842-694: Is heated and compressed deep underground. Methanogenic organisms produce methane from a variety of sources, principally carbon dioxide. During petroleum production, natural gas is sometimes flared rather than being collected and used. Before natural gas can be burned as a fuel or used in manufacturing processes, it almost always has to be processed to remove impurities such as water. The byproducts of this processing include ethane , propane , butanes , pentanes , and higher molecular weight hydrocarbons. Hydrogen sulfide (which may be converted into pure sulfur ), carbon dioxide , water vapor , and sometimes helium and nitrogen must also be removed. Natural gas

2940-526: Is in terms of creating demand. In other words, it is the ability of a product's design to generate demand by satisfying customer expectations. But product design affects not only demand generation but also manufacturing processes, cost, quality, and lead time. The product design affects the associated supply chain and its requirements directly, including manufacturing, transportation, quality, quantity, production schedule, material selection, production technologies, production policies, regulations, and laws. Broadly,

3038-463: Is increasingly being utilized in supply chain management, especially in the strategic purchasing and supply management sector. Effective application of big data can improve the performance of supply chain activities through improved decision-making capabilities. Moore et al. note a trend towards strategic supply-base reduction as a mechanism for leading businesses to reduce costs and improve supplier-related performance, and similarly Ogden identifies

3136-448: Is managed by a cross-functional team including representatives from logistics, production, purchasing, finance, marketing, and research and development. While each process interfaces with key customers and suppliers, the processes of customer relationship management and supplier relationship management form the critical linkages in the supply chain. The American Productivity and Quality Center (APQC) Process Classification Framework (PCF) SM

3234-402: Is more significant than ever. In addition, as supply, and therefore competition, among companies for the limited market demand increases and as pricing and other marketing elements become less distinguishing factors, product design likewise plays a different role by providing attractive features to generate demand. In this context, demand generation is used to define how attractive a product design

3332-403: Is natural gas produced from shale . Because shale's matrix permeability is too low to allow gas to flow in economical quantities, shale gas wells depend on fractures to allow the gas to flow. Early shale gas wells depended on natural fractures through which gas flowed; almost all shale gas wells today require fractures artificially created by hydraulic fracturing . Since 2000, shale gas has become

3430-408: Is odorless, odorizers such as mercaptan (which smells like rotten eggs ) are commonly added to it for safety so that leaks can be readily detected. Natural gas is a fossil fuel that is formed when layers of organic matter (primarily marine microorganisms) decompose under anaerobic conditions and are subjected to intense heat and pressure underground over millions of years. The energy that

3528-406: Is often stored underground [references about geological storage needed]inside depleted gas reservoirs from previous gas wells, salt domes , or in tanks as liquefied natural gas. The gas is injected in a time of low demand and extracted when demand picks up. Storage nearby end users helps to meet volatile demands, but such storage may not always be practicable. With 15 countries accounting for 84% of

3626-452: Is preparing to export natural gas. Floating liquefied natural gas (FLNG) is an innovative technology designed to enable the development of offshore gas resources that would otherwise remain untapped due to environmental or economic factors which currently make them impractical to develop via a land-based LNG operation. FLNG technology also provides a number of environmental and economic advantages: Many gas and oil companies are considering

3724-548: Is primarily dependent on proximity to markets (pipelines), and regulatory restrictions. Natural gas can be indirectly exported through the absorption in other physical output. The expansion of shale gas production in the US has caused prices to drop relative to other countries. This has caused a boom in energy intensive manufacturing sector exports, whereby the average dollar unit of US manufacturing exports has almost tripled its energy content between 1996 and 2012. A "master gas system"

3822-429: Is primarily used in the northern hemisphere. North America and Europe are major consumers. Often well head gases require removal of various hydrocarbon molecules contained within the gas. Some of these gases include heptane , pentane , propane and other hydrocarbons with molecular weights above methane ( CH 4 ). The natural gas transmission lines extend to the natural gas processing plant or unit which removes

3920-716: Is sometimes informally referred to simply as "gas", especially when it is being compared to other energy sources, such as oil, coal or renewables. However, it is not to be confused with gasoline , which is also shortened in colloquial usage to "gas", especially in North America. Natural gas is measured in standard cubic meters or standard cubic feet . The density compared to air ranges from 0.58 (16.8 g/mole, 0.71 kg per standard cubic meter) to as high as 0.79 (22.9 g/mole, 0.97 kg per scm), but generally less than 0.64 (18.5 g/mole, 0.78 kg per scm). For comparison, pure methane (16.0425 g/mole) has

4018-604: Is traded on a "dry gas" basis and is required to be commercially free from objectionable odours, materials, and dust or other solid or liquid matter, waxes, gums and gum forming constituents, which might damage or adversely affect operation of equipment downstream of the custody transfer point. LNG carrier ships transport liquefied natural gas (LNG) across oceans, while tank trucks can carry LNG or compressed natural gas (CNG) over shorter distances. Sea transport using CNG carrier ships that are now under development may be competitive with LNG transport in specific conditions. Gas

4116-409: Is transported at high pressure, typically above 200 bars (20,000 kPa; 2,900 psi). Compressors and decompression equipment are less capital intensive and may be economical in smaller unit sizes than liquefaction/regasification plants. Natural gas trucks and carriers may transport natural gas directly to end-users, or to distribution points such as pipelines. In the past, the natural gas which

4214-416: Is turned into liquid at a liquefaction plant, and is returned to gas form at regasification plant at the terminal . Shipborne regasification equipment is also used. LNG is the preferred form for long distance, high volume transportation of natural gas, whereas pipeline is preferred for transport for distances up to 4,000 km (2,500 mi) over land and approximately half that distance offshore. CNG

4312-702: The extended enterprise , and the use of the term "chain" and the linear structure it appears to represent have been criticized as "harder to relate to the way supply networks really operate. A chain is actually a complex and dynamic supply and demand network. As part of their efforts to demonstrate ethical practices , many large companies and global brands are integrating codes of conduct and guidelines into their corporate cultures and management systems . Through these, corporations are making demands on their suppliers (facilities, farms, subcontracted services such as cleaning, canteen, security etc.) and verifying, through social audits , that they are complying with

4410-458: The 2013 Savar building collapse with more than 1,100 victims have led to widespread discussions about corporate social responsibility across global supply chains. Wieland and Handfield (2013) suggest that companies need to audit products and suppliers and that supplier auditing needs to go beyond direct relationships with first-tier suppliers (those who supply the main customer directly). They also demonstrate that visibility needs to be improved if

4508-659: The European Commission issued a Communication concerning "a better functioning food supply chain in Europe", addressing the three sectors of the European economy which comprise the food supply chain: agriculture, food processing industries, and the distribution sectors. An earlier interim report on food prices (published in December 2008) had already raised concerns about the food supply chain. Arising out of

4606-570: The Importer Security Filing (ISF) and additional provisions of the Certified Cargo Screening Program. EU's draft supply chain law are due diligence requirements to protect human rights and the environment in the supply chain. With the increasing globalization and easier access to different kinds of alternative products in today's markets, the contribution of product design to generating demand

The main pipeline is 781 kilometres (485 mi) long and 559 millimetres (22.0 in) in diameter. The lateral to Port Pirie is 78 kilometres (48 mi) at 168 millimetres (6.6 in) continuing 87.7 kilometres (54.5 mi) to Whyalla at 219 millimetres (8.6 in). The Angaston lateral

4802-549: The required standard . A lack of transparency in the supply chain can bar consumers from knowledge of where their purchases originated and facilitate socially irresponsible practices. In 2018, the Loyola University Chicago 's Supply and Value Chain Center found in a survey that 53% of supply chain professionals considered ethics to be "extremely" important to their organization. Marshall L. Fisher (1997) asks

4900-427: The supply chain can result in natural gas having a similar carbon footprint to other fossil fuels overall. Natural gas can be found in underground geological formations , often alongside other fossil fuels like coal and oil (petroleum). Most natural gas has been created through either biogenic or thermogenic processes. Thermogenic gas takes a much longer period of time to form and is created when organic matter

4998-548: The 19th century, natural gas was primarily obtained as a by-product of producing oil . The small, light gas carbon chains came out of solution as the extracted fluids underwent pressure reduction from the reservoir to the surface, similar to uncapping a soft drink bottle where the carbon dioxide effervesces . The gas was often viewed as a by-product, a hazard, and a disposal problem in active oil fields. The large volumes produced could not be used until relatively expensive pipeline and storage facilities were constructed to deliver

5096-406: The 20th century, it was increasingly referred to as simply "gas." In order to highlight its role in exacerbating the climate crisis , however, many organizations have criticized the continued use of the word "natural" in referring to the gas. These advocates prefer the term "fossil gas" or "methane gas" as better conveying to the public its climate threat. A 2020 study of Americans' perceptions of

5194-432: The US had peaked three times, with current levels exceeding both previous peaks. It reached 24.1 trillion cubic feet per year in 1973, followed by a decline, and reached 24.5 trillion cubic feet in 2001. After a brief drop, withdrawals increased nearly every year since 2006 (owing to the shale gas boom ), with 2017 production at 33.4 trillion cubic feet and 2019 production at 40.7 trillion cubic feet. After

5292-427: The US, over one-third of households (>40 million homes) cook with gas. Natural gas dispensed in a residential setting can generate temperatures in excess of 1,100 °C (2,000 °F) making it a powerful domestic cooking and heating fuel. Stanford scientists estimated that gas stoves emit 0.8–1.3% of the gas they use as unburned methane and that total U.S. stove emissions are 28.1 gigagrams of methane. In much of

5390-523: The United States begins with localized use. In the seventeenth century, French missionaries witnessed the American Indians setting fire to natural gas seeps around lake Erie, and scattered observations of these seeps were made by European-descended settlers throughout the eastern seaboard through the 1700s. In 1821, William Hart dug the first commercial natural gas well in the United States at Fredonia, New York , United States, which led in 1858 to

5488-538: The assumptions of globalization, outsourcing, and linear supply chains and to envision alternatives; in this example this could lead to local and circular supply chains. Supply chain resilience has been identified as an important business issue. The United Kingdom's Confederation of British Industry reported in 2014 that a significant number of businesses had reshored parts of their supply chain to European locations, with many identifying supply chain resilience as "a key factor in their decision to do so". Incidents like

5586-702: The bottoms of the gashouse ovens was often used for roofing and other waterproofing purposes, and when mixed with sand and gravel was used for paving streets. Huge quantities of natural gas (primarily methane) exist in the form of clathrates under sediment on offshore continental shelves and on land in arctic regions that experience permafrost , such as those in Siberia . Hydrates require a combination of high pressure and low temperature to form. In 2013, Japan Oil, Gas and Metals National Corporation (JOGMEC) announced that they had recovered commercially relevant quantities of natural gas from methane hydrate. The image below

5684-654: The decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other hydrocarbons. Natural gas can be burned for heating, cooking, and electricity generation . Consisting mainly of methane, natural gas is rarely used as a chemical feedstock . The extraction and consumption of natural gas is a major industry. When burned for heat or electricity , natural gas emits fewer toxic air pollutants, less carbon dioxide, and almost no particulate matter compared to other fossil and biomass fuels. However, gas venting and unintended fugitive emissions throughout

Similarly, supply chain mapping involves documenting information regarding all participants in an organization's supply chain and assembling the information as

5978-620: The difficulty of "keeping a supply chain with India unbroken" during the British expedition to Tibet . A typical supply chain can be divided into two stages namely, production and distribution stages. In the production stage, components and semi-finished parts are produced in manufacturing centres. The components are then put together in an assembly plant. The distribution stage consists of central and regional distribution centres that transport products to end-consumers. Mentzer et al. suggest that at least three entities are required for there to be

6076-446: The eastern US in the late 19th and early 20th centuries were simple by-product coke ovens that heated bituminous coal in air-tight chambers. The gas driven off from the coal was collected and distributed through networks of pipes to residences and other buildings where it was used for cooking and lighting. (Gas heating did not come into widespread use until the last half of the 20th century.) The coal tar (or asphalt ) that collected in

6174-446: The economic and environmental benefits of floating liquefied natural gas (FLNG). There are currently projects underway to construct five FLNG facilities. Petronas is close to completion on their FLNG-1 at Daewoo Shipbuilding and Marine Engineering and are underway on their FLNG-2 project at Samsung Heavy Industries . Shell Prelude is due to start production 2017. The Browse LNG project will commence FEED in 2019. Natural gas

6272-538: The efficiency of distribution. The term "logistics" applies to activities within one company or organization involving product distribution, whereas "supply chain" additionally encompasses manufacturing and procurement, and therefore has a much broader focus as it involves multiple enterprises (including suppliers, manufacturers, and retailers) working together to meet a customer need for a product or service. However, John Mills et al . note that "early research" on supply chains focused on internal supply relationships within

6370-483: The enacting of policies that can improve occupational safety and health management in organizations. In fact, international organizations with presence in other nations have a responsibility to ensure that workers are well protected by policies in an organization to avoid safety related incidents. Many agribusinesses and food processors source raw materials from smallholder farmers. This is particularly true in certain sectors, such as coffee , cocoa and sugar . Over

6468-407: The face of change". For a long time, the interpretation of resilience in the sense of engineering resilience (or robustness) prevailed in supply chain management, leading to the notion of persistence . A popular implementation of this idea is given by measuring the time-to-survive and the time-to-recover of the supply chain, allowing identification of weak points in the system. More recently,

6566-547: The flow of information and finances is part of the chain as well as the product or service. Fazel Zarandi et al. add "buyer-seller relations" (at each stage), in addition to the flow of information, as the third main component of a supply chain. Mentzer et al. remind readers also that the focus of a supply chain is on the product or service in its end state: they refer to "the supply chain for candy " and "the supply chain for clothing". Individual supply chain actors may be positioned at different points in different supply chains:

6664-497: The formation of the Fredonia Gas Light Company . Further such ventures followed near wells in other states, until technological innovations allowed the growth of major long distance pipelines from the 1920s onward. By 2009, 66,000 km (16,000 cu mi) (or 8%) had been used out of the total 850,000 km (200,000 cu mi) of estimated remaining recoverable reserves of natural gas. In

6762-461: The fuel found that, across political identifications, the term "methane gas" led to better estimates of its harms and risks. Natural gas can come out of the ground and cause a long-burning fire. In ancient Greece , the gas flames at Mount Chimaera contributed to the legend of the fire-breathing creature Chimera . In ancient China , gas resulting from the drilling for brines was first used by about 400 BC. The Chinese transported gas seeping from

6860-435: The gas needs to be cooled down and compressed, as the friction in the pipeline causes the gas to heat up. Many existing pipelines in the US are close to reaching their capacity, prompting some politicians representing northern states to speak of potential shortages. The large trade cost implies that natural gas markets are globally much less integrated, causing significant price differences across countries. In Western Europe ,

6958-517: The gas pipeline network is already dense. New pipelines are planned or under construction between Western Europe and the Near East or Northern Africa . Whenever gas is bought or sold at custody transfer points, rules and agreements are made regarding the gas quality. These may include the maximum allowable concentration of CO 2 , H 2 S and H 2 O . Usually sales quality gas that has been treated to remove contamination

7056-896: The gas to consumer markets. Until the early part of the 20th century, most natural gas associated with oil was either simply released or burned off at oil fields. Gas venting and production flaring are still practised in modern times, but efforts are ongoing around the world to retire them, and to replace them with other commercially viable and useful alternatives. In addition to transporting gas via pipelines for use in power generation, other end uses for natural gas include export as liquefied natural gas (LNG) or conversion of natural gas into other liquid products via gas to liquids (GTL) technologies. GTL technologies can convert natural gas into liquids products such as gasoline, diesel or jet fuel. A variety of GTL technologies have been developed, including Fischer–Tropsch (F–T), methanol to gasoline (MTG) and syngas to gasoline plus (STG+). F–T produces

7154-526: The ground in crude pipelines of bamboo to where it was used to boil salt water to extract the salt in the Ziliujing District of Sichuan . Natural gas was not widely used before the development of long distance pipelines in the early twentieth century. Before that, most use was near to the source of the well, and the predominant gas for fuel and lighting during the industrial revolution was manufactured coal gas. The history of natural gas in

The processed natural gas may then be used for residential, commercial and industrial uses. Natural gas flowing in the distribution lines is called mid-stream natural gas and is often used to power engines which rotate compressors. These compressors are required in

7350-470: The interpretations of resilience in the sense of ecological resilience and social–ecological resilience have led to the notions of adaptation and transformation , respectively. A supply chain is thus interpreted as a social-ecological system which – similar to an ecosystem (e.g. forest) – is able to constantly adapt to external environmental conditions and – through the presence of social actors and their ability to foresight – also to transform itself into

7448-612: The largest proven gas reserves. Sources that consider that Russia has by far the largest proven reserves include the US Central Intelligence Agency (47,600 km ) and Energy Information Administration (47,800 km ), as well as the Organization of Petroleum Exporting Countries (48,700 km ). Contrarily, BP credits Russia with only 32,900 km , which would place it in second, slightly behind Iran (33,100 to 33,800 km , depending on

7546-483: The motives for and performance efficacy of vertical integration differ by global region. Incorporating SCM successfully leads to a new kind of competition on the global market, where competition is no longer of the company-versus-company form but rather takes on a supply-chain-versus-supply-chain form. The primary objective of SCM is to fulfill customer demands through the most efficient use of resources, including distribution capacity, inventory , and labor. In theory,

7644-433: The natural gas can be transported. Natural gas extracted from oil wells is called casinghead gas (whether or not truly produced up the annulus and through a casinghead outlet) or associated gas. The natural gas industry is extracting an increasing quantity of gas from challenging, unconventional resource types : sour gas , tight gas , shale gas , and coalbed methane . There is some disagreement on which country has

7742-409: The need for a more comprehensive measurement program." However, the abundance of options for potential performance metrics to use is seen as a challenge for supply chain managers. One approach is to relate multiple measures in a hierarchical structure so that interdependencies and the contribution of multiple indicators to the "key" or most significant metrics can be more easily seen. Hofman suggests that

7840-443: The past 20 years, there has been a shift towards more traceable supply chains. Rather than purchasing crops that have passed through several layers of collectors, firms are now sourcing directly from farmers or trusted aggregators. The drivers for this change include concerns about food safety , child labor and environmental sustainability as well as a desire to increase productivity and improve crop quality. In October 2009,

7938-441: The pores of the gas reservoir get depleted. One method to deal with this problem is to re-inject dried gas free of condensate to maintain the underground pressure and to allow re-evaporation and extraction of condensates. More frequently, the liquid condenses at the surface, and one of the tasks of the gas plant is to collect this condensate. The resulting liquid is called natural gas liquid (NGL) and has commercial value. Shale gas

8036-469: The question in a key article, "Which is the right supply chain for your product?" Fisher, and also Naylor, Naim and Berry (1999), identify two matching characteristics of supply chain strategy: a combination of "functional" and "efficient", or a combination of "responsive" and "innovative" (Harrison and Godsell). Mentzer et al. distinguish between "direct supply chains", "extended supply chains", and "ultimate supply chains"; in their usage: In each case,

8134-550: The source). It is estimated that there are about 900,000 km of "unconventional" gas such as shale gas, of which 180,000 km may be recoverable. In turn, many studies from MIT , Black & Veatch and the US Department of Energy predict that natural gas will account for a larger portion of electricity generation and heat in the future. The world's largest gas field is the offshore South Pars / North Dome Gas-Condensate field , shared between Iran and Qatar. It

8232-406: The success of the supply chain depends on the product design and the capabilities of the supply chain, but the reverse is also true: the success of the product depends on the supply chain that produces it. According to an industrial engineering study which looked at a process for Design for Supply Chain (DFSC), since the product design imposes multiple requirements on the supply chain, then once

8330-554: The supplier's supplier to the customer's customer". It includes delivery and order fulfillment performance, production flexibility, warranty and returns processing costs, inventory and asset turns, and other factors in evaluating the overall effective performance of a supply chain. A supply chain can often be split into different segments: the earlier stages of a supply chain, such as raw material processing and manufacturing , determine their break-even point by considering production costs relative to market price. The later stages of

8428-471: The supply cannot be directly controlled and that smart and electronic technologies play a key role to improve visibility. Finally, they highlight that collaboration with local partners, across the industry and with universities is crucial to successfully manage social responsibility in supply chains. This incident also highlights the need to improve workers safety standards in organizations. Hoi and Lin (2012) note that corporate social responsibility can influence

8526-467: The supply chain at any point where residual value is recyclable. Supply chains link value chains . Suppliers in a supply chain are often ranked by "tier", with first-tier suppliers supplying directly to the client, second-tier suppliers supplying to the first tier, and so on. The phrase "supply chain" may have been first published in a 1905 article in The Independent which briefly mentions

8624-414: The supply chain has the ability to help optimize the entire supply chain rather than to sub-optimize based on local optimization. This will lead to better-planned overall production and distribution, which can cut costs and give a more attractive final product, leading to better sales and better overall results for the companies involved. This is one form of vertical integration . Yet, it has been shown that

8722-418: The supply chain. Supply chain consultant Anthony Tarantino has identified a number of best practices affecting the resilience and operation of supply chains, including the formation of multi-disciplinary centres of excellence, hybrid supply chain organizations which optimize the balance between centralization and de-centralization, and more extensive use of both structured and unstructured data . Big data

8820-598: The third peak in December 2019, extraction continued to fall from March onward due to decreased demand caused by the COVID-19 pandemic in the US . The 2021 global energy crisis was driven by a global surge in demand as the world quit the economic recession caused by COVID-19, particularly due to strong energy demand in Asia. Because of its low density, it is not easy to store natural gas or to transport it by vehicle. Natural gas pipelines are impractical across oceans, since

8918-446: The three key indicators of a well-functioning supply chain are: A Cranfield University boardroom survey in 2010 found evidence that many organizations recognized the importance of the supply chain contribution to their business success, with a focus on cost, customer lead-time and customer quality being the primary performance indicators. Supply chain resilience is "the capacity of a supply chain to persist, adapt, or transform in

9016-412: The transmission line to pressurize and repressurize the mid-stream natural gas as the gas travels. Typically, natural gas powered engines require 35–39 MJ/m (950–1,050 BTU/cu ft) natural gas to operate at the rotational name plate specifications. Several methods are used to remove these higher molecular weighted gases for use by the natural gas engine. A few technologies are as follows: In

9114-497: The two reports, the Commission established a "European Food Prices Monitoring Tool", an initiative developed by Eurostat and intended to "increase transparency in the food supply chain". In March 2022 the Commission noted "the need for EU agriculture and food supply chains to become more resilient and sustainable". The supply chain in the fashion industries has some unique properties, as clothing fashion changes several times

9212-569: The upstream and downstream elements of supply-chain management (SCM). The SCOR ( Supply-Chain Operations Reference ) model, developed by a consortium of industry and the non-profit Supply Chain Council (now part of APICS ) became the cross-industry de facto standard defining the scope of supply-chain management. SCOR measures total supply-chain performance. It is a process reference model for supply-chain management, extending "from

9310-502: The worldwide extraction, access to natural gas has become an important issue in international politics, and countries vie for control of pipelines. In the first decade of the 21st century, Gazprom , the state-owned energy company in Russia, engaged in disputes with Ukraine and Belarus over the price of natural gas, which have created concerns that gas deliveries to parts of Europe could be cut off for political reasons. The United States

9408-494: Was invented in Saudi Arabia in the late 1970s, ending any necessity for flaring. Satellite and nearby infra-red camera observations, however, shows that flaring and venting are still happening in some countries. Natural gas is used to generate electricity and heat for desalination . Similarly, some landfills that also discharge methane gases have been set up to capture the methane and generate electricity. Natural gas

9506-473: Was privatised in 1995 and bought by Queensland Investment Corporation , the parent company of Epic Energy in April 2013. The pipeline system now consists of a total of 1,185 kilometres (736 mi) of high pressure gas pipelines, including 326 kilometres (203 mi) of laterals. The main lateral spurs are the one to Port Pirie and Whyalla and the one to Angaston . The Angaston spur can also feed gas into

9604-567: Was recovered in the course of recovering petroleum could not be profitably sold, and was simply burned at the oil field in a process known as flaring . Flaring is now illegal in many countries. Additionally, higher demand in the last 20–30 years has made production of gas associated with oil economically viable. As a further option, the gas is now sometimes re- injected into the formation for enhanced oil recovery by pressure maintenance as well as miscible or immiscible flooding. Conservation, re-injection, or flaring of natural gas associated with oil
