West Texas Intermediate (WTI) is a grade or mix of crude oil; the term is also used to refer to the spot price, the futures price, or assessed price for that oil. In colloquial usage, WTI usually refers to the WTI Crude Oil futures contract traded on the New York Mercantile Exchange (NYMEX). The WTI oil grade is also known as Texas light sweet, oil produced from any location can be considered WTI if the oil meets the required qualifications. Spot and futures prices of WTI are used as a benchmark in oil pricing. This grade is described as light crude oil because of its low density and sweet because of its low sulfur content.
Brent Crude may refer to any or all of the components of the Brent Complex, a physically and financially traded oil market based around the North Sea of Northwest Europe; colloquially, Brent Crude usually refers to the price of the ICE Brent Crude Oil futures contract or the contract itself. The original Brent Crude referred to a trading classification of sweet light crude oil first extracted from the Brent oilfield in the North Sea in 1976. As production from the Brent oilfield declined to zero in 2021, crude oil blends from other oil fields have been added to the trade classification. The current Brent blend consists of crude oil produced from the Forties, Oseberg, Ekofisk, and Troll oil fields.
The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water: if its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks.
Light crude oil is liquid petroleum that has a low density and flows freely at room temperature. It has a low viscosity, low specific gravity and high API gravity due to the presence of a high proportion of light hydrocarbon fractions. It generally has a low wax content. Light crude oil receives a higher price than heavy crude oil on commodity markets because it produces a higher percentage of gasoline and diesel fuel when converted into products by an oil refinery.
Sour crude oil is crude oil containing a high amount of the impurity sulfur. It is common to find crude oil containing some impurities. When the total sulfur level in the oil is more than 0.5%, the oil is called "sour".
The Iranian Oil Bourse, International Oil Bourse, Iran Petroleum ExchangeKish Exchange or Oil Bourse in Kish also known as Iran Crude Oil Exchange, is a commodity exchange, which opened its first phase on 17 February 2008.
The price of oil, or the oil price, generally refers to the spot price of a barrel of benchmark crude oil—a reference price for buyers and sellers of crude oil such as West Texas Intermediate (WTI), Brent Crude, Dubai Crude, OPEC Reference Basket, Tapis crude, Bonny Light, Urals oil, Isthmus, and Western Canadian Select (WCS). Oil prices are determined by global supply and demand, rather than any country's domestic production level.
Connacher Oil and Gas Limited is a Calgary-based exploration, development and production company active in the production and sale of bitumen in the Athabasca oil sands region. Connacher's shares used to trade on the Toronto Stock Exchange, but it was de-listed in 2016, after filing for insolvency.
A benchmark crude or marker crude is a crude oil that serves as a reference price for buyers and sellers of crude oil. There are three primary benchmarks, West Texas Intermediate (WTI), Brent Blend, and Dubai Crude. Other well-known blends include the OPEC Reference Basket used by OPEC, Tapis Crude which is traded in Singapore, Bonny Light used in Nigeria, Urals oil used in Russia and Mexico's Isthmus. Energy Intelligence Group publishes a handbook which identified 195 major crude streams or blends in its 2011 edition.
The OPEC Reference Basket (ORB), also referred to as the OPEC Basket, is a weighted average of prices for petroleum blends produced by OPEC members. It is used as an important benchmark for crude oil prices. OPEC has often attempted to keep the price of the OPEC Basket between upper and lower limits, by increasing and decreasing production. This makes the measure important for market analysts. The OPEC Basket, including a mix of light and heavy crude oil products, is heavier than both Brent crude oil, and West Texas Intermediate crude oil.
The Dubai Mercantile Exchange (DME) is a commodity exchange based in Dubai currently listing its flagship futures contract, DME Oman Crude Oil Futures Contract (OQD). Launched in 2007, the DME aims to become the crude oil pricing benchmark for the Asian market with its Oman Crude Oil contract, like the Intercontinental Exchange’s (ICE) North Sea Brent is to Europe and the New York Mercantile Exchange’s (NYMEX) West Texas Intermediate is to North America.
Tapis crude is a Malaysian crude oil used as a pricing benchmark in Singapore. Tapis is very light, with an API gravity of 43°-45°, and very sweet, with only about 0.04% sulfur. While it is not traded on a market like Brent Crude or West Texas Intermediate (WTI), it is often used as an oil marker or price referencing indicator for Asia and Australia.
Urals oil is a reference oil brand used as a basis for pricing of the Russian export oil mixture. It is a mix of heavy sour oil of the Urals and the Volga region with light oil of Western Siberia. Other reference oils are Brent, West Texas Intermediate and Dubai.
The Argus Sour Crude Index (ASCI) is a pricing tool used by buyers, sellers and traders of imported crude oil for use in long-term contracts.
Launched by the Dubai Mercantile Exchange (DME) on 1 June 2007, the DME Oman Crude Oil Futures Contract (OQD) is the Asian crude oil pricing benchmark. The contract is traded on the CME Group’s electronic platform CME Globex, and cleared through CME Clearport.
Western Canadian Select (WCS) is a heavy sour blend of crude oil that is one of North America's largest heavy crude oil streams and, historically, its cheapest. It was established in December 2004 as a new heavy oil stream by EnCana (now Cenovus), Canadian Natural Resources, Petro-Canada (now Suncor) and Talisman Energy (now Repsol Oil & Gas Canada). It is composed mostly of bitumen blended with sweet synthetic and condensate diluents and 21 existing streams of both conventional and unconventional Alberta heavy crude oils at the large Husky Midstream General Partnership terminal in Hardisty, Alberta. Western Canadian Select—the benchmark for heavy, acidic (TAN <1.1) crudes—is one of many petroleum products from the Western Canadian Sedimentary Basin oil sands. Calgary-based Husky Energy, now a subsidiary of Cenovus, had joined the initial four founders in 2015.
Indian Basket (IB), also known as Indian Crude Basket, is weighted average of Dubai and Oman (sour) and the Brent Crude (sweet) crude oil prices. It is used as an indicator of the price of crude imports in India and Government of India watches the index when examining domestic price issues.
