(kerosene, lamp oil, jet fuel), product of petroleum refining with start and end of distillation at 180–240 <sup>o</sup>C; fuel for jet engines.
the smallest particle of a chemical element or compound that can exist independently, while maintaining the important characteristics of the matter.
products resulting from crude oil refining with start and end of distillation at 70 – 215 <sup>o</sup>C; motor fuel for numerous internal combustion engines; types – aviation petrol, leaded petrol, unleaded petrol.
Main oil pipeline
below-ground, steel pipeline for the delivery of crude oil from production petroleum fields into harbours, loading stations, tank cars or tank trucks or directly to petroleum refineries.
Main gas pipeline
below-ground, steel pipeline for the transport of natural gas from production petreolum and gas fields for further treatment, underground storage or consumer centres
gaseous hydrocarbon (CH<sub>4</sub>), the lightest and principal ingredient of natural and refined gas; used primarily as an energy source.
migration of oil and natural gas from parent rocks – place of genesis, through permeable middles of the lithosphere up to favourable geological structures – reservoirs of petroleum and gas.
(MS), facility in a petroleum field where recovered fluid from the well (mixture of petroleum, gas and water) is separated into petroleum, natural gas and water; where produced quantities are measured and each fluid is delivered separately for further technological processing.
Measuring and regulation station
(MRS), facility of a gas line system where the pressure of natural gas is lowered to the pressure of the gas distribution network or some other pressure necessary for consumers who are directly connected to the gas line system; point where delivered gas volumes are measured and, according to need, odorisation takes place.
Naphtha residue/bunker oil
heavy fuel oil; used as fuel in thermal electrical power plants, power plants and industry, as well as engine fuel for big engines.
paurograined sediment, rich with organic matter, in a natural habitat generates substantial quantities of hydrocarbons for inducing economic accumulations.
