| Naphtha |
| A volatile, colourless product of petroleum distillation. Within the refinery, naphtha is used primarily in motor gasoline production, via catalytic reforming and blending with straight-run gasoline from crude distillation. Naphtha is also a feedstock for petrochemical production, and is sold as a paint solvent, and as a fuel. |

| Naphthenes |
| One of the three basic hydrocarbon classifications found naturally in crude oil. (The others are paraffins and olefins). Naphthenes, also called cycloparaffins, are widely used as petrchemical feedstocks: most naphthenes are derivatives of cyclopentane or cyclohexane. |
| |
| Natural Gas |
| Naturally occurring mixtures of hydrocarbon gases and vapors, mostly methane (CH4). |
| |
| Natural Gas Liquids (NGLs) |
| The complete range of easily liquefied hydrocarbon gases associated with the production and processing of natural gas: ethane, propane and butanes.
|
| |
| Netback |
| In the upstream sector, the revenue available to the producer of crude oil and/or natural gas to pay the cost of production, that is, total revenue less taxes, royalties and, in some cases, gathering charges. In the downstream sector, an industry term referring to the net FOB cost of production offered on a delivered or CIF basis. It is arrived at by subtracting from the landed price all costs of shipment from the orginal port of origin. |
| |
| New Field Wildcat (NFW) |
| Lies within one and one-half mile limit from production, and is considered the most exploratory. |
| |
| New Pool Wildcat (NPW) |
| Lies within one and one-half miles of a producer. |
| |
| Non-Associated Gas |
| Natural gas not in contact with crude oil in the reservoir, or natural gas in contact with crude oil, where the volume of oil is small and where production of such gas does not significantly affect recovery of the crude oil. |
| |
| Non-Conventional Generation |
| The generation of electricity by any means other than hydroelectric generation, thermal generation using nuclear fuel, coal, oil or natural gas, gas turbine generation using oil and natural gas, or internal combustion generation. Examples would be solar power and wind energy. |
| |
| Nuclear Waste |
| Radioactive products of the nuclear fuel system: irradiated fuel (bundles) and reactor wastes which have been accumulated in filters, or other devices and materials associated with operating and maintenance activities. |
| |
| Nuclear Waste Management |
Systems to use or dispose of nuclear wastes to eliminate or substatially reduce the risk of injury to the health of living organisms. The systems may involve the following:
Nuclear Waste Management / Immobilization
Encasing the radioactive products within a solid protective material (glass, ceramic, bitumen) to protect against dissolution by water.
Nuclear Waste Management / Storage
Emplacement of radioactive material in a safe location with the intention of retrieving it.
Nuclear Waste Management / Disposal
Permanent placement of radioactive material with no intention of retrieving it. |
