| oil boom (A floating device used to contain oil on a body of water. Once the boom has been inflated, it is towed downwind of the oil slick and formed into a U-shape; under the influence of wind, the oil becomes trapped within the boom. Skimming equipment travels into the boom enclosure and the oil is pumped into containers) | petrolioari eusteko hesi | |
| oil disaster (The disaster caused by the dumping and accidental spillage of oil into waterways from ships and land-based or offshore installations. Oil pollution may destroy or damage aquatic life and wildlife such as birds, contaminate water supplies and create fire hazards) | petrolio-hondamendi | |
| oil exploration (No definition needed) | petrolio-esplorazio | |
| oil exploration (No definition needed) | petrolio-miaketa | |
| oil exploration (No definition needed) | petrolio-prospekzio | |
| oil extraction (Recovery of oil by surface mining, as in tar sands or oil shales, or from tunnels in a shallow reservoir) | petrolio-erauzketa | |
| oil pipeline (A line of pipe connected to valves and other control devices, for conducting oil) | oliobide | |
| oil pollution (Contamination of any ecosystem, but usually of freshwater or marine ecosystems, by oil or other petroleum products) | petrolio-poluzio | |
| oil pollution abatement (There are various systems for the abatement of oil pollution at sea: the "Load-on-top" system involves passing the washing from tank cleaning operations and residue from discharge of the original ballast water to an empty cargo tank nominated as the "slop" tank. Fresh oil cargo is loaded on top of the final residue left after further discharges of water, the resulting mixture being acceptable to refineries despite some additional cost in removing the salt and water. Under the International Convention for the Prevention of Pollution from Ships, 1973, all oil-carrying ships will be required to be capable of operating with this method of retention, or alternatively to discharge to reception facilities. Another method consists in spraying on the oil dispersives and/or blasting straw and sawdust, functioning as "blotting paper", onto water, beaches, rocks and docks. The Vikoma System for the containment of oil spills at sea, developed by British Petroleum, a seaboom of about 500 metres in length, is inflated and towed downwind of the oil slick and formed into a U-shape; under the influence of wind, the oil becomes trapped within the boom. Skimming equipment travels into the boom enclosure and the oil is pumped into containers) | petrolio-poluzioaren gutxitze | |
| oil production (The petroleum industry is a complex industry utilizing complex combination of interdependent operations engaged in the storage and transportation, separation of crude molecular constituents, molecular cracking, molecular rebuilding and solvent finishing to produce petrochemical products. Treatment may involve oil separation, precipitation, adsorption, and biological treatment. The refining operations can be divided into four major steps: separation, conversion, treating, and blending. The crude oil is first separated into selected fractions (gasoline, kerosine, fuel oil, etc.). Some of the less valuable products such as heavy naphtha, are converted to products with a greater sale value such as gasoline. The final step is the blending of the refined base stocks with each other and various additive to meet final product specifications. The major pollutants emitted are sulphur oxides, nitrogen oxides, hydrocarbons, carbon monoxide, and malodorous materials; chain) | petrolio-ekoizpen | |
| oil recovery vessel (Boats used for recovering oil spilled at sea from oil tankers. The recommended procedure is to contain and physically recover the spill with or without the use of adsorbents. This approach entails three processes: 1. confinement of the spill by spill booms; 2. recovery of the spill by sorbing agents; 3. physical removal of the contained oil by oil pick-up devices) | petrolioa berreskuratzeko itsasontzi | |
| oil refinery (System of process units used to convert crude petroleum into fuels, lubricants, and other petroleum-derived products) | petrolio-findegi | |
| oil refining (The separation of petroleum mixtures into their component parts) | petrolioaren fintze | |
| oil refining (The separation of petroleum mixtures into their component parts) | fintze | |
| oil residue recuperation (The recovery of oil that is leftover or left behind, usually following the primary containment operations for an oil spill) | petrolio-hondakinen berreskuratze | |
| oil shale (A kerogen-bearing, finely laminated brown or black sedimentary rock that will yield liquid or gaseous hydrocarbons on distillation) | eskisto bituminoso | |
| oil slick (The mass of oil that floats on a surface of water, which is discharged accidentally, naturally or by design, and can be moved by currents, tides and the wind) | petrolio-geruza | |
| oil spill (The accidental release of oil, or other petroleum products usually into freshwater or marine ecosystems, and usually in large quantities. It can be controlled by chemical dispersion, combustion, mechanical containment, and absorption) | marea beltz | |
| oil tanker (A very large ship which carries crude oil or other petroleum products in big tanks) | petrolio-ontzi | |
