Density
ratio of mass and volume; value which shows the mass (in kg) of a volume unit (in m<sup>3</sup>); often in derived units kg/l; for example, water density is 1 kg/l, petroleum density is 0.8000 – 0.9000 kg/l.
Gasoline hydrocarbons
fraction of petroleum or condensate with a boiling point between 15 and 2000C, consisting of low-molecular hydro carbonic components containing less then 12 atoms of carbon.
Geophysical methods
methods of applied geophysics for measuring the geological characteristics of the underground for the purpose of discovering new possible reservoirs of the raw material: gravimetrics, magneto-metrics, seismics, electro-logging etc.
Geophysics
science which observes the physical characteristics of the Earth (temperature, magnetism, gravity, radioactivity, electrical resistance of rocks, etc.); combination of physics and geology.
Geology
science of the genesis, structure and development of the Earth as a whole, especially the Earth’s crust (lithosphere).
Geological trap
geological object under ground, reservoir of certain raw material, isolated from the environment by impermeable deposits; characteristic of reservoirs of petroleum and natural gas.
Gas-lift
lifting column of oil/petroleum in a well using compressed natural gas when oil/petroleum can no longer be lifted to the surface by the reservoir energy.
