Wiki Wiki Summary
Natural gas Natural law (Latin: ius naturale, lex naturalis) is a system of law based on a close observation of human nature, and based on values intrinsic to human nature that can be deduced and applied independently of positive law (the express enacted laws of a state or society). According to natural law theory, all people have inherent rights, conferred not by act of legislation but by "God, nature, or reason." Natural law theory can also refer to "theories of ethics, theories of politics, theories of civil law, and theories of religious morality."In the Western tradition it was anticipated by the Pre-Socratics, for example in their search for principles that governed the cosmos and human beings.
Liquefied natural gas Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure).
Compressed natural gas Compressed natural gas (CNG) is a fuel gas made of petrol which is mainly composed of methane (CH4), compressed to less than 1% of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 20–25 MPa (2,900–3,600 psi), usually in cylindrical or spherical shapes.
List of countries by natural gas production This is a list of countries by natural gas production based on statistics from The World Factbook, and OECD members natural gas production by International Energy Agency (down) \n\n\n== Countries by natural gas production ==\nThe data in the following table comes from The World Factbook.
Natural gas vehicle A natural gas vehicle (NGV) is an alternative fuel vehicle that uses compressed natural gas (CNG) or liquefied natural gas (LNG). Natural gas vehicles should not be confused with autogas vehicles powered by liquefied petroleum gas (LPG), mainly propane, a fuel with a fundamentally different composition.
Natural-gas processing Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing impurities, contaminants and higher molecular mass hydrocarbons to produce what is known as pipeline quality dry natural gas. Natural gas has to be processed in order to prepare it for final use and ensure that elimination of contaminants.Natural-gas processing starts underground or at the well-head.
Natural-gas condensate Natural-gas condensate, also called natural gas liquids, is a low-density mixture of hydrocarbon liquids that are present as gaseous components in the raw natural gas produced from many natural gas fields. Some gas species within the raw natural gas will condense to a liquid state if the temperature is reduced to below the hydrocarbon dew point temperature at a set pressure.
Natural gas prices Natural gas prices, as with other commodity prices, are mainly driven by supply and demand fundamentals. However, natural gas prices may also be linked to the price of crude oil and petroleum products, especially in continental Europe.
Petroleum product Petroleum products are materials derived from crude oil (petroleum) as it is processed in oil refineries. Unlike petrochemicals, which are a collection of well-defined usually pure organic compounds, petroleum products are complex mixtures.
Saint-Petersburg International Mercantile Exchange The Saint-Petersburg International Mercantile Exchange (SPIMEX) is a Russian commodity exchange that was incorporated in 2008. It has offices in Moscow, Saint Petersburg and Irkutsk.
Wool Wool is the textile fibre obtained from sheep and other animals, including cashmere and mohair from goats, qiviut from muskoxen, hide and fur clothing from bison, angora from rabbits, and other types of wool from camelids.Wool consists of protein together with a small percentage of lipids. In this regard it is chemically quite distinct from cotton, which is mainly cellulose.
Volume correction factor In thermodynamics, the Volume Correction Factor (VCF), also known as Correction for the effect of Temperature on Liquid (CTL), is a standardized computed factor used to correct for the thermal expansion of fluids, primarily, liquid hydrocarbons at various temperatures and densities. It is typically a number between 0 and 2, rounded to five decimal places which, when multiplied by the observed volume of a liquid, will return a "corrected" value standardized to a base temperature (usually 60 °Fahrenheit or 15 °Celsius).
Crack spread Crack spread is a term used on the oil industry and futures trading for the differential between the price of crude oil and petroleum products extracted from it. The spread approximates the profit margin that an oil refinery can expect to make by "cracking" the long-chain hydrocarbons of crude oil into useful shorter-chain petroleum products.
Midstream Mindstream (citta-santāna) in Buddhist philosophy is the moment-to-moment continuum (Sanskrit: saṃtāna) of sense impressions and mental phenomena, which is also described as continuing from one life to another.\n\n\n== Definition ==\nCitta-saṃtāna (Sanskrit), literally "the stream of mind", is the stream of succeeding moments of mind or awareness.
Final good A final good or consumer good is a final product ready for sale that is used by the consumer to satisfy current wants or needs, unlike intermediate goods which is utilized to produce other goods. A microwave oven or a bicycle is a final good, whereas the parts purchased to manufacture it are intermediate goods.
Regulation Regulation is the management of complex systems according to a set of rules and trends. In systems theory, these types of rules exist in various fields of biology and society, but the term has slightly different meanings according to context.
Formula One regulations The numerous Formula One regulations, made and enforced by the FIA and later the FISA, have changed dramatically since the first Formula One World Championship in 1950. This article covers the current state of F1 technical and sporting regulations, as well as the history of the technical regulations since 1950.
Vehicle emission standard Emission standards are the legal requirements governing air pollutants released into the atmosphere. Emission standards set quantitative limits on the permissible amount of specific air pollutants that may be released from specific sources over specific timeframes.
Yoda conditions In programming jargon, Yoda conditions (also called Yoda notation) is a programming style where the two parts of an expression are reversed from the typical order in a conditional statement. A Yoda condition places the constant portion of the expression on the left side of the conditional statement.
Dirichlet conditions In mathematics, the Dirichlet conditions are sufficient conditions for a real-valued, periodic function f to be equal to the sum of its Fourier series at each point where f is continuous. Moreover, the behavior of the Fourier series at points of discontinuity is determined as well (it is the midpoint of the values of the discontinuity).
Twenty-one Conditions The Twenty-one Conditions, officially the Conditions of Admission to the Communist International, refer to the conditions, most of which were suggested by Vladimir Lenin, to the adhesion of the socialist parties to the Third International (Comintern) created in 1919. The conditions were formally adopted by the Second Congress of the Comintern in 1920.
Conditions (album) Conditions is the debut studio album by Australian rock band The Temper Trap, released in Australia through Liberation Music on 19 June 2009. It was later released in the United Kingdom on 10 August 2009.
Nervous Conditions Nervous Conditions is a novel by Zimbabwean author Tsitsi Dangarembga, first published in the United Kingdom in 1988. It was the first book published by a black woman from Zimbabwe in English.
Wolfe conditions In the unconstrained minimization problem, the Wolfe conditions are a set of inequalities for performing inexact line search, especially in quasi-Newton methods, first published by Philip Wolfe in 1969.In these methods the idea is to find\n\n \n \n \n \n min\n \n x\n \n \n f\n (\n \n x\n \n )\n \n \n {\displaystyle \min _{x}f(\mathbf {x} )}\n for some smooth \n \n \n \n f\n :\n \n \n R\n \n \n n\n \n \n →\n \n R\n \n \n \n {\displaystyle f\colon \mathbb {R} ^{n}\to \mathbb {R} }\n . Each step often involves approximately solving the subproblem\n\n \n \n \n \n min\n \n α\n \n \n f\n (\n \n \n x\n \n \n k\n \n \n +\n α\n \n \n p\n \n \n k\n \n \n )\n \n \n {\displaystyle \min _{\alpha }f(\mathbf {x} _{k}+\alpha \mathbf {p} _{k})}\n where \n \n \n \n \n \n x\n \n \n k\n \n \n \n \n {\displaystyle \mathbf {x} _{k}}\n is the current best guess, \n \n \n \n \n \n p\n \n \n k\n \n \n ∈\n \n \n R\n \n \n n\n \n \n \n \n {\displaystyle \mathbf {p} _{k}\in \mathbb {R} ^{n}}\n is a search direction, and \n \n \n \n α\n ∈\n \n R\n \n \n \n {\displaystyle \alpha \in \mathbb {R} }\n is the step length.
Conditions races Conditions races are horse races in which the weights carried by the runners are laid down by the conditions attached to the race. Weights are allocated according to the sex of the runners, with female runners carrying less weight than males; the age of the runners, with younger horses receiving weight from older runners to allow for relative maturity, referred to as weight for age; and the quality of the runners, with horses that have won certain values of races giving weight to less successful entrants.
Conditions of Learning Conditions of Learning, by Robert M. Gagné, was originally published in 1965 by Holt, Rinehart and Winston and describes eight kinds of learning and nine events of instruction. This theory of learning involved two steps.
Standard temperature and pressure Standard temperature and pressure (STP) are standard sets of conditions for experimental measurements to be established to allow comparisons to be made between different sets of data. The most used standards are those of the International Union of Pure and Applied Chemistry (IUPAC) and the National Institute of Standards and Technology (NIST), although these are not universally accepted standards.
Operation Mincemeat Operation Mincemeat was a successful British deception operation of the Second World War to disguise the 1943 Allied invasion of Sicily. Two members of British intelligence obtained the body of Glyndwr Michael, a tramp who died from eating rat poison, dressed him as an officer of the Royal Marines and placed personal items on him identifying him as the fictitious Captain (Acting Major) William Martin.
Arithmetic Arithmetic (from Ancient Greek ἀριθμός (arithmós) 'number', and τική [τέχνη] (tikḗ [tékhnē]) 'art, craft') is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots. In the 19th century, Italian mathematician Giuseppe Peano formalized arithmetic with his Peano axioms, which are highly important to the field of mathematical logic today.
Bitwise operation In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits. It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor.
Special Activities Center The Special Activities Center (SAC) is a division of the Central Intelligence Agency responsible for covert operations and paramilitary operations. The unit was named Special Activities Division (SAD) prior to 2015.
Operations management Operations management is an area of management concerned with designing and controlling the process of production and redesigning business operations in the production of goods or services. It involves the responsibility of ensuring that business operations are efficient in terms of using as few resources as needed and effective in meeting customer requirements.
Operations research Operations research (British English: operational research), often shortened to the initialism OR, is a discipline that deals with the development and application of advanced analytical methods to improve decision-making. It is sometimes considered to be a subfield of mathematical sciences.
Emergency operations center An emergency operations center (EOC) is a central command and control facility responsible for carrying out the principles of emergency preparedness and emergency management, or disaster management functions at a strategic level during an emergency, and ensuring the continuity of operation of a company, political subdivision or other organization.\nAn EOC is responsible for strategic direction and operational decisions and does not normally directly control field assets, instead leaving tactical decisions to lower commands.
Operation (mathematics) In mathematics, an operation is a function which takes zero or more input values (called operands) to a well-defined output value. The number of operands (also known as arguments) is the arity of the operation.
Profit (economics) An economic profit is the difference between the revenue a commercial entity has received from its outputs and the opportunity costs of its inputs. It equals to total revenue minus total cost, including both explicit and implicit costs.
Porter's five forces analysis Porter's Five Forces Framework is a method of analysing the operating environment of a competition of a business. It draws from industrial organization (IO) economics to derive five forces that determine the competitive intensity and, therefore, the attractiveness (or lack thereof) of an industry in terms of its profitability.
Risk Factors
CONOCOPHILLIPS Item 1A RISK FACTORS You should carefully consider the following risk factors in addition to the other information included in this Annual Report on Form 10-K Each of these risk factors could adversely affect our business, operating results and financial condition, as well as adversely affect the value of an investment in our common stock
A substantial or extended decline in crude oil, natural gas and natural gas liquids prices, as well as refining margins, would reduce our operating results and cash flows, and could impact our future rate of growth and the carrying value of our assets
Our revenues, operating results and future rate of growth are highly dependent on the prices we receive for our crude oil, natural gas, natural gas liquids and refined products
Historically, the markets for crude oil, natural gas, natural gas liquids and refined products have been volatile and may continue to be volatile in the future
Many of the factors influencing the prices of crude oil, natural gas, natural gas liquids and refined products are beyond our control
These factors include, among others: • Worldwide and domestic supplies of, and demand for, crude oil, natural gas, natural gas liquids and refined products
• The cost of exploring for, developing, producing, refining and marketing crude oil, natural gas, natural gas liquids and refined products
• The ability of the members of OPEC and other producing nations to agree to and maintain production levels
• The worldwide military and political environment, uncertainty or instability resulting from an escalation or additional outbreak of armed hostilities or further acts of terrorism in the United States, or elsewhere
• The price and availability of alternative and competing fuels
• Domestic and foreign governmental regulations and taxes
• General economic conditions worldwide
The long-term effects of these and other conditions on the prices of crude oil, natural gas, natural gas liquids and refined products are uncertain
Generally, our policy is to remain exposed to market prices of commodities; however, management may elect to hedge the price risk of our crude oil, natural gas, natural gas liquids and refined products
Lower crude oil, natural gas, natural gas liquids and refined products prices may reduce the amount of these commodities that we can produce economically, which may reduce our revenues, operating income and cash flows
Significant reductions in commodity prices could require us to reduce our capital expenditures and impair the carrying value of our assets
Estimates of crude oil and natural gas reserves depend on many factors and assumptions, including various assumptions that are based on conditions in existence as of the dates of the estimates
Any material changes in those conditions or other factors affecting those assumptions could impair the quantity and value of our crude oil and natural gas reserves
36 ______________________________________________________________________ The proved crude oil and natural gas reserve information relating to us included in this annual report has been derived from engineering estimates prepared by our personnel
The estimates were calculated using crude oil and natural gas prices in effect as of December 31, 2005, as well as other conditions in existence as of that date
Any significant future price changes will have a material effect on the quantity and present value of our proved reserves
Future reserve revisions could also result from changes in, among other things, governmental regulation
Reserve estimation is a subjective process that involves estimating volumes to be recovered from underground accumulations of crude oil and natural gas that cannot be directly measured
Estimates of economically recoverable crude oil and natural gas reserves and of future net cash flows depend upon a number of variable factors and assumptions, including: • Historical production from the area, compared with production from other comparable producing areas
• The assumed effects of regulations by governmental agencies
Assumptions concerning future crude oil and natural gas prices
Assumptions concerning future operating costs, severance and excise taxes, development costs and workover and remedial costs
As a result, different petroleum engineers, each using industry-accepted geologic and engineering practices and scientific methods, may produce different estimates of reserves and future net cash flows based on the same available data
Because of the subjective nature of crude oil and natural gas reserve estimates, each of the following items may differ materially from the amounts or other factors estimated: • The amount and timing of crude oil and natural gas production
• The revenues and costs associated with that production
• The amount and timing of future development expenditures
The discounted future net revenues from our reserves should not be considered as the market value of the reserves attributable to our properties
As required by rules adopted by the SEC, the estimated discounted future net cash flows from our proved reserves, as described in the supplemental oil and gas operations disclosures on pages 183 through 185, are based generally on prices and costs as of the date of the estimate, while actual future prices and costs may be materially higher or lower
In addition, the 10 percent discount factor, which SEC rules require to be used to calculate discounted future net revenues for reporting purposes, is not necessarily the most appropriate discount factor based on our cost of capital and the risks associated with our business and the crude oil and natural gas industry in general
If we are unsuccessful in acquiring or finding additional reserves, our future crude oil and natural gas production would decline, thereby reducing our cash flows and results of operations, negatively impacting our financial condition
The rate of production from crude oil and natural gas properties generally declines as reserves are depleted
Except to the extent that we acquire additional properties containing proved reserves, conduct successful exploration and development activities, or, through engineering studies, identify additional or secondary recovery reserves, our proved reserves will decline materially as we produce crude oil and natural gas
Accordingly, to the extent that we are not successful in replacing the crude oil and natural gas we produce 37 ______________________________________________________________________ with good prospects for future production, our business will decline
Creating and maintaining an inventory of projects depends on many factors, including: • Obtaining rights to explore, develop and produce crude oil and natural gas in promising areas
Efficient and profitable operation of mature properties
We may not be able to find or acquire additional reserves at acceptable costs
Crude oil price increases and environmental regulations may reduce our refined product margins
The profitability of our R&M segment depends largely on the margin between the cost of crude oil and other feedstocks we refine and the selling prices we obtain for refined products
Our overall profitability could be adversely affected by the availability of supply and rising crude oil and other feedstock prices that we do not recover in the marketplace
Refined product margins historically have been volatile and vary with the level of economic activity in the various marketing areas, the regulatory climate, logistical capabilities and the available supply of refined products
In addition, environmental regulations, particularly the 1990 amendments to the Clean Air Act, have imposed, and are expected to continue to impose, increasingly stringent and costly requirements on our refining and marketing operations, which may reduce refined product margins
We will continue to incur substantial capital expenditures and operating costs as a result of compliance with, and changes in, environmental laws and regulations, and, as a result, our profitability could be materially reduced
Our businesses are subject to numerous laws and regulations relating to the protection of the environment
These laws and regulations continue to increase in both number and complexity and affect our operations with respect to, among other things: • The discharge of pollutants into the environment
• The handling, use, storage, transportation, disposal and clean-up of hazardous materials and hazardous and non-hazardous wastes
• The dismantlement, abandonment and restoration of our properties and facilities at the end of their useful lives
We have incurred and will continue to incur substantial capital, operating and maintenance, and remediation expenditures as a result of these laws and regulations
To the extent these expenditures, as with all costs, are not ultimately reflected in the prices of our products and services, our operating results will be adversely affected
The specific impact of these laws and regulations on us and our competitors may vary depending on a number of factors, including the age and location of operating facilities, marketing areas and production processes
We may also be required to make material expenditures to: • Modify operations
• Install pollution control equipment
• Perform site cleanups
38 ______________________________________________________________________ • Curtail operations
We may become subject to liabilities that we currently do not anticipate in connection with new, amended or more stringent requirements, stricter interpretations of existing requirements or the future discovery of contamination
In addition, any failure by us to comply with existing or future laws could result in civil or criminal fines and other enforcement actions against us
Our, and our predecessors’, operations also could expose us to civil claims by third parties for alleged liability resulting from contamination of the environment or personal injuries caused by releases of hazardous substances
Environmental laws are subject to frequent change and many of them have become more stringent
In some cases, they can impose liability for the entire cost of cleanup on any responsible party, without regard to negligence or fault, and impose liability on us for the conduct of others or conditions others have caused, or for our acts that complied with all applicable requirements when we performed them
Worldwide political and economic developments could damage our operations and materially reduce our profitability and cash flows
Local political and economic factors in international markets could have a material adverse effect on us
Approximately 65 percent of our crude oil, natural gas and natural gas liquids production in 2005 was derived from production outside the United States, and 66 percent of our proved reserves, as of December 31, 2005, were located outside the United States
There are many risks associated with operations in international markets, including changes in foreign governmental policies relating to crude oil, natural gas, natural gas liquids or refined product pricing and taxation, other political, economic or diplomatic developments, changing political conditions and international monetary fluctuations
These risks include, among others: • Political and economic instability, war, acts of terrorism and civil disturbances
• The possibility that a foreign government may seize our property, with or without compensation, may attempt to renegotiate or revoke existing contractual arrangements and concessions, or may impose additional taxes or royalties
Fluctuating currency values, hard currency shortages and currency controls
Continued hostilities and turmoil in the world and the occurrence or threat of future terrorist attacks could affect the economies of the United States and other developed countries
A lower level of economic activity could result in a decline in energy consumption, which could cause our revenues and margins to decline and limit our future growth prospects
More specifically, our energy-related assets may be at greater risk of future terrorist attacks than other possible targets
A direct attack on our assets, or assets used by us, could have a material adverse effect on our operations, financial condition, results of operations and prospects
These risks could lead to increased volatility in prices for crude oil, natural gas, natural gas liquids and refined products and could increase instability in the financial and insurance markets, making it more difficult for us to access capital and to obtain the insurance coverage that we consider adequate
39 ______________________________________________________________________ Actions of the US government through tax and other legislation, executive order and commercial restrictions could reduce our operating profitability both in the United States and abroad
The US government can prevent or restrict us from doing business in foreign countries
These restrictions and those of foreign governments have in the past limited our ability to operate in, or gain access to, opportunities in various countries
Actions by both the United States and host governments have affected operations significantly in the past and will continue to do so in the future
We also are exposed to fluctuations in foreign currency exchange rates
We do not comprehensively hedge our exposure to currency rate changes, although we may choose to selectively hedge certain working capital balances, firm commitments, cash returns from affiliates and/or tax payments
These efforts may not be successful
Changes in governmental regulations may impose price controls and limitations on production of crude oil and natural gas
Our operations are subject to extensive governmental regulations
From time to time, regulatory agencies have imposed price controls and limitations on production by restricting the rate of flow of crude oil and natural gas wells below actual production capacity in order to conserve supplies of crude oil and natural gas
Because legal requirements are frequently changed and subject to interpretation, we cannot predict the effect of these requirements
Our operations are subject to business interruptions and casualty losses, and we do not insure against all potential losses, so we could be seriously harmed by unexpected liabilities
Our exploration and production operations are subject to unplanned occurrences, including blowouts, explosions, fires, loss of well control, formations with abnormal pressures, spills and adverse weather
In addition, our refining, marketing and transportation operations are subject to business interruptions due to scheduled refinery turnarounds and unplanned events such as explosions, fires, pipeline interruptions, pipeline ruptures, crude oil or refined product spills, inclement weather or labor disputes
Our operations are also subject to the additional hazards of pollution, releases of toxic gas and other environmental hazards and risks, as well as hazards of marine operations, such as capsizing, collision and damage or loss from severe weather conditions
All such hazards could result in loss of human life, significant property and equipment damage, environmental pollution, impairment of operations and substantial losses to us
These hazards have adversely affected us in the past, and litigation arising from a catastrophic occurrence in the future at one of our locations may result in our being named as a defendant in lawsuits asserting potentially large claims or being assessed potentially substantial fines by governmental authorities
In addition, we are exposed to risks inherent in any business, such as terrorist attacks, equipment failures, accidents, theft, strikes, protests and sabotage, that could disrupt or interrupt operations
We maintain insurance against many, but not all, potential losses or liabilities arising from these operating hazards in amounts that we believe to be prudent
Uninsured losses and liabilities arising from operating hazards could reduce the funds available to us for exploration, drilling, production and other capital expenditures and could materially reduce our profitability
Our investments in joint ventures decrease our ability to manage risk
We conduct many of our operations through joint ventures in which we may share control with our joint-venture partners
As with any joint-venture arrangement, differences in views among the joint-venture participants may result in delayed decisions or in failures to agree on major issues
There is the risk that our joint-venture partners may at any time have economic, business or legal interests or goals that are 40 ______________________________________________________________________ inconsistent with those of the joint venture or us
There is also risk that our joint-venture partners may be unable to meet their economic or other obligations and that we may be required to fulfill those obligations alone
Failure by us, or an entity in which we have a joint-venture interest, to adequately manage the risks associated with any acquisitions or joint ventures could have a material adverse effect on the financial condition or results of operations of our joint ventures and, in turn, our business and operations
We anticipate entering into additional joint ventures with other entities
We cannot assure that we will undertake such joint ventures or, if undertaken, that such joint ventures will be successful
We may not be successful in continuing to grow through acquisitions, and any further acquisitions may require us to obtain additional financing or could result in dilution of earnings per share
A substantial portion of our growth over the last several years has been attributable to acquisitions
Risks associated with acquisitions include those relating to: • Diversion of management time and attention from our existing businesses and other priorities
Difficulties in integrating the financial, technological and management standards, processes, procedures and controls of an acquired business into those of our existing operations
Liability for known or unknown environmental conditions or other contingent liabilities not covered by indemnification or insurance
• Greater than anticipated expenditures required for compliance with environmental or other regulatory standards, or for investments to improve operating results
Difficulties in achieving anticipated operational improvements
We may not be successful in continuing to grow through acquisitions
In addition, the financing of future acquisitions may require us to incur additional indebtedness, which could limit our financial flexibility, or to issue additional equity, which could result in dilution of the ownership interests of existing stockholders
Any acquisitions that we do consummate may not produce the anticipated benefits or may have adverse effects on our business and operating results
Our results of operations could be adversely affected by goodwill impairments
As a result of mergers and acquisitions, at year-end 2005 we had approximately dlra15 billion of goodwill on our balance sheet
Goodwill is not amortized, but instead must be tested at least annually for impairment by applying a fair-value-based test
Goodwill is deemed impaired to the extent that its carrying amount exceeds the residual fair value of the reporting unit
Although our latest tests indicate that no goodwill impairment is currently required, future deterioration in market conditions could lead to goodwill impairments that could have a substantial negative affect on our profitability
