Terms A-Z

Natural Gas

A naturally occurring mixture of hydrocarbon and non-hydrocarbon gases found in porous geologic formations beneath the earth's surface, often in association with petroleum. The principal constituent is methane. 1) Dry Gas - Gas whose water content has been reduced by a dehydration process. Gas containing little or no hydrocarbons commercially recoverable as liquid product. Specified small quantities of liquids are permitted by varying statutory definitions in certain states. 2) Liquefied Natural Gas (LNG). Natural gas cooled to a point of liquefaction for transportation to a market. 3) Sour Gas - Gas found in its natural state, containing such amounts of compounds of sulfur as to make it impractical to use, without purifying, because of its corrosive effect on piping and equipment. 4) Sweet Gas - Gas found in its natural state, containing such small amounts of compounds of sulfur that it can be used without purifying, with no deleterious effect on piping and equipment. 5) Wet Gas - Wet natural gas is unprocessed natural gas or partially processed natural gas produced from strata containing condensable hydrocarbons. The term is subject to varying legal definitions as specified by certain state statutes. (The usual maximum allowable is 7lbs./MMcf water content and .02 gallons/Mcf of Natural Gasoline.)

No-Notice Delivery Service

Delivery of natural gas on as-needed basis, without the need to precisely specify the delivery quantity in advance. No-notice delivery is generally made at the city gate or burner tip.

Nominated Volume

The physical quantity of gas requested, typically in MMBtu/day, for a specific contract or for all contracts at a specific point.

Nomination

A request for a physical quantity of gas under a specific purchase, sales or transportation agreement or for all contracts at a specific point. A nomination will continue for specified number of days or until superseded by another service request for the same contract.

Non-Firm Power

Power or power-producing capacity supplied or available subject to interruption.
