The Platts industry glossary is continuously updated. Please let us know
if there is an entry you would like us to add, clarify or expand, or if
you think we have made a mistake in any of our definitions.
The glossary covers common terms and abbreviations from the oil, power,
petrochemicals, nuclear, gas, coal and metals markets and industries.
15-Day Brent
The 15-Day Brent crude oil market is so-called because a seller must
give a buyer a minimum 15 days notice of the intended loading dates for
a cargo of Brent Blend North Sea crude oil in
any particular month traded. 15-Day Brent is traded in discreet months.
At the point where the buyer - who may be at the end of a long trading
chain - is informed of the loading dates, the cargo becomes a so-called Dated Brent cargo.
A/F
Abbreviation for anti-freeze, one of the larger end-uses of monoethylene
glycol.
abandon

butylene.
alternating
current (AC)
A periodic current, the average value of which over a period is zero.
Typically refers to a current that reverses its direction at regularly
recurring intervals of time and that has alternately positive and negative
values. Almost all electricity utilities generate AC electricity because
it can easily be transformed to higher or lower voltages
alternating
current distribution
The supply of electricity from one or more major receiving stations to
the point of consumption. Energy is generally supplied at a voltage that
can be directly used by large rotating machinery and step-down transformers
are used to reduce the voltage for most commercial or residential utilization
American style option
An option which can be exercised by the buyer (holder) at anytime during
its life
ampere (amp)
The unit of measurement of electrical current produced in a circuit by
1 volt acting through a resistance of 1 ohm. The measure of the rate of
flow of electrons past a given point in an electric conductor such as
a power line
ancillary services
Any service required by a system operator to deliver electricity to the
ultimate consumer. Ancillary services include balancing services, load
following, or providing kilovars (reactive power).
Andrew’s Pitchfork
Three parallel trendlines are drawn linking a major low or high with
a point either side of this marking an intermediate high or low. The lines
are extended to generate support/ resistance levels. The lines look a
bit like the prongs of a pitchfork, hence the indicator’s name.
Aniline point
Reports the aromatics content of a mixture.
anode
A rectangular plate of metal cast in a shape suitable for refining by
the electrolytic process.
ANS
Alaska North Slope crude oil.
anthracite
A hard, black coal with high energy content, often referred to as hard
coal
API
Usually: American Petroleum Institute. But note that there is
an Italian oil company called Anonyma Petroli Italiana, universally referred
to in Europe as API.
API gravity
An arbitrary scale expressing the gravity or density of liquid petroleum
products devised jointly by the American Petroleum Institute and the National
Bureau of Standards. The measuring scale is calibrated in terms of degrees
API. Oil with the least specific gravity has the highest API gravity.
The formula for determining API Gravity is:
API gravity = (141.5/specific gravity at 60 degrees F) – 131.5.
APT
Ammonium paratungstate. Intermediate product derived from tungsten concentrates.
ARA
Amsterdam-Rotterdam-Antwerp. Abbreviation commonly used in shipping to
designate discharge or loading at one of these three ports.
Arab Gulf
This phrase and its abbreviation AG are current in some sectors of the
oil industry, especially the tanker world, as a designator for the Persian
Gulf, which is the correct name in international law for the body
of water bordered by the UAE, Saudi Arabia, Qatar, Kuwait, Iraq and Iran.
Note that there is a Gulf of Arabia which is not the same piece
of sea as the Persian Gulf.
Aramco
Technically refers to a now-defunct US-Saudi company. But in practice
widely used to designate the company’s modern-day descendant Saudi
Aramco.
arbitrage
The simultaneous purchase of a commodity/derivative in one market and
the sale of the same, or similar, commodity/derivative in another market
in order to exploit price differentials
aromatics
Group of petrochemicals characterized by a ring structure, produced in
refinery reformers and petrochemical plants. The most commonly traded
are benzene, toluene and xylenes. Used for chemical production or as high-octane
components for gasoline blending.
asph
Occasional abbreviation for asphaltene.
asphalt
1. A mixture of bitumen and mineral aggregate as prepared for the construction
of roads or in other paving uses.
2. In the US, asphalt refers to the product known as bitumen in the rest
of the world.
assay
A chemical test performed on a sample of ores or minerals to determine
the amount of valuable metals contained.
assessment
A Platts assessment is the product of a market survey and the application
of strict methodological rules to determine the repeatable tradable price
range for a commodity during the assessed period. Assessment typically
aims to zero in on these typical transactable levels by discarding unrepresentative
market information (out-of-market bids, offers and transactions), and
the process differs in this respect from indexation, which is an inclusive process, averaging all available market information. Platts produces indexes
in highly liquid markets, for example North American natural gas; and
assessments in illiquid markets, such as those for physical oil. Platts
assessments typically are published as a low-high range for each instrument.
See Platts Guide to Specifications and also Frequently Asked Questions
for details of Platts methodologies.
associated gas
Also known as wet gas. natural gas produced in association with
crude oil. Non-associated gas, or dry gas, is natural gas occurring on
its own. Also, LPG is produced as an associated gas and must be treated

barrel
A volumetric unit of measure for crude oil and petroleum products. 1
barrel is 42 US gallons, 35 imperial gallons or 159 liters. There are
roughly 7.33 bbl of crude oil to a tonne, but the precise conversion obviously
depends on the specific gravity of the oil.
base gas

period of time at a steady rate. The minimum continuous load or demand
in a power system over a given period of time
base load capacity
The generation units normally used to meet demand around-the-clock.
base load plant
A plant normally operated to take all or part of the minimum continuous
load of a system, and which consequently produces electricity at an essentially
constant rate. A base load plant typically has relatively high fixed costs
and low unit operating costs. Traditionally, nuclear plants have been
considered as base load plants.
base metal

blowmolding
A process by which polymers are “blown” into a tubular mold.
Also refers to a specific grade of polyethylene, sometimes abbreviated
as bmldg.
Bollinger bands
A system based on the premise that prices revert to their mean. The standard
deviation of the moves away from the mean are used to form two bands around
the price. Whenever the price breaks below or above the band, it is deemed
too extreme a move and therefore liable to correct back from the standard
deviation towards the mean of the price.
BPA
Bonneville Power Authority. Electricity utility in the US Pacific Northwest,
supplying power to several aluminum smelters. Acceptable as second-reference
abbreviation.
breakout
A sudden breakout of prices from a chart pattern that has been forming
for some time. It marks the end of a period of uncertainty. The breakout
point can often be used to guess how far prices will go in that direction.
Brent blend
The most commonly traded North Sea crude oil. Brent has an API of about 37.5. The blend is technically a mix of crude from the Shell
UK-operated Brent field and the BP-operated Ninian field. The blend is,
however, commonly referred to simply as Brent.

on or before a specified date. The grantor of the option is obliged to
deliver the future at the fixed price if the holder exercises the option
candlesticks
A Japanese charting system which maps the open- high-low-and close of
periodic price movements. A box is drawn around the open and close, and
painted white if the close is above the open, and black if the close is
below the open. The boxes and their little heads and tails look like candles
and their wicks. Candlestick studies are full of exotic terms like Morning
Star and Dark Cloud Cover; these describe how the black and white candles
look, and can be interpreted as buy or sell signals.

network. Also used to increase voltages, reduce loadings, and increase
available kW output from generators. Capacitor ratings typically given
in Megavars.
capacity
The power output rating of a generator, typically in megawatts, measured

The process of burning natural gas in conjunction with another fuel.
Cofiring can reduce sulfur dioxide (SO2) and nitrogen oxide (NOx) emissions,
the precursors of acid rain.
cogeneration
The production of both electricity and useful thermal energy from the
same energy source. Natural gas tends to be a favored fuel for combined-cycle
cogeneration units, in which waste heat is converted to electricity.
combined cycle
The combination of one or more gas turbine and steam turbines in an electric
generation plant. An electric generating technology in which electricity
is produced from otherwise lost waste heat exiting from one or more gas
(combustion) turbines. The heat is routed to a conventional boiler or
to a heat recovery steam generator for use by a steam turbine in the production
of electricity. This process increases the efficiency of the electric
generating unit
combined heat and power
plant
Power plant, usually embedded, which produces both electric and thermal
energy in the form of steam. See cogeneration.
Commodity Channel
Index
CCI measures the variation of an instrument’s price from its mean. High
/ low values indicate that prices have moved too far from their mean.
The usual range is +/- 100 and anything outside this is overbought or
oversold.
compressed natural
gas
Compressed natural gas used in vehicles and in other applications not
attached to a pipeline.
compressor station
Facility that moves gas through transmission lines or into storage by
creating pressure differentials. Most stations use some of the gas moving
through the line as fuel.
concentrates
A fine, powdery product of the milling process containing valuable metal
and from which most of the waste material in the ore has been eliminated
and discarded as tailings. Often abbreviated to concs.
condensate
Very high API crude “oil”, which in its natural state is in
gaseous form but which condenses to liquid upon production. OPEC has for
many years argued over the precise definition of condensates, since it
does not include them in individual countries’ crude production quotas.
See NGL.
conductor
A substance or body, usually in the form of a wire, cable, or busbar,
that allows a current of electricity to pass continuously along it
congestion
When prices trade at similar levels over a period of time, the chart
becomes cluttered with business at these levels and is referred to as
‘congested’. Congestion areas are often seen as providing support/resistance.
They are the levels at which, rather than breaking into new ground, prices
tend to bog down and become trapped.
connection
The physical junction (transmission lines, transformers, switch gear,
etc) between two electric systems permitting the transfer of electricity
consolidation
All this means is that prices are moving in a broadly sideways range
after a sharp move in one direction. If the prices have risen sharply,
the gains are ‘consolidated’, often for several days after the
major move.
contango
Market situation where prices are higher for forward delivery dates than
for nearer delivery dates. See also backwardation.
Conti Index
Platts demand-weighted index of continental European power assessments.
contract
A binding agreement between a buyer and a seller in a transaction.
contract for differences
Crude oil swap, tied to published price assessments, which exchanges
floating short-term risk for fixed risk.
contract price
Periodic (monthly/quarterly/annual) price agreed between sellers and
buyers of commodities for term business. Often abbreviated to CP. Most
oil contract prices are “floating”, that is they are tied to
spot market assessments published by Platts or other market pricing services
rather than set at outright levels.
coolant
A substance circulating through a nuclear reactor to remove or transfer
heat. Most common coolants are carbon dioxide, water (light), and heavy
water.
CP
See contract price.
crack spread
The simultaneous purchase or sale of crude against the sale or purchase

the product prices into dollars per barrel and subtracting the crude price.
cracked
Adjective normally referring to molecules broken by non-distillation
refining processes. See cracking.
cracked fuel
Residue remaining after a straight run fuel has been processed by enhanced
refining methods. See cracking.
cracking
Refining process to break large molecules into smaller ones. Principal
cracking techniques are:
Thermal cracking:
Heating of hydrocarbons to very high temperatures, usually above 450ý
C. Thermal cracking is no longer widely used, except in:
Visbreaking:
Thermal cracking of viscous crude residues to make fuel oil, and in:
Delayed Coking:
Thermal cracking of atmospheric/vacuum residues to make electrode grade
coke.
Catalytic cracking:
Cracking using catalysts to enhance molecule breaking, particularly in
the production of high octane gasoline.
Hydrocracking:
While thermal and catalytic cracking produce shorter hydrocarbon molecules
largely by disposing of the excess carbon atoms, hydrocracking inserts
hydrogen atoms to achieve the same effect.
Steam cracking:
A petrochemical process which produces olefins, particularly ethylene,
and, in some cases, aromatics. Similar to thermal cracking
Co-Cracking:
A petrochemical process in which the c4 stream from an ethylene plant
is recycled into the feedstock.

1/2 month futures cycle (individual commodities do not necessarily follow
this).

of a call option will buy more of the futures contract if it rises in
value towards the strike price (as the probability of being declared upon
rises towards 100%). The grantor of a put option will typically sell more
of the underlying futures contract if it slides in value (as the probability
of being declared upon rises towards 100%)

futures market against a price swing in the holder’s favor (see delta
hedging).
UNL
Abbreviation for unleaded.
uptrend
A price pattern characterized by subsequent rising highs and rising lows.
uranium
The heaviest naturally occurring element (atomic number 92). It is metallic
and slightly radioactive. Its only substantial use today is as a raw material
for generating electricity via nuclear fission. Ranging in atomic mass
from 227 to 240, uranium has 14 isotopes, of which only three occur naturally:
uranium-238, uranium-235, and uranium-234.
Uranium-238 – comprises 99.283% by weight of natural uranium
(ie uranium whose isotopic composition, as it occurs in nature, has not
been altered)and is not fissile, but is fertile. It usually absorbs any
neutrons which strike it and as a result is transformed into plutonium-239,
a fissile isotope of plutonium.
Uranium-235 – the only naturally occurring isotope of uranium
which is capable of fission. Natural uranium contains approximately 0.711%
by weight of uranium-235.
Uranium-234 – exists in very small quantities in natural
uranium (0.005% by weight) and is not fissile in thermal reactors.
The remaining isotopes are created synthetically. Uranium-233 is fissile
and is obtained by the irradiation of thorium-232 with neutrons. Uranium-232,
-236, and –237 are found in irradiated nuclear fuel and are not fissile.
