Drilling mud permeated with bubbles of gas from downhole. The circulation of such mud can be severely impaired, thus seriously affecting drilling operations

A natural gas liquid with a low vapor pressure, compared with natural gasoline and liquefied petroleum gas. It is produced from a deep well where the temperature and pressure are high. Gas condenses as it rises up the wellbore and reaches the surface as condensate

Removal of particulates from gas

Instrument to measure the calorific value and/or the composition of the gas

Gas cap gas is a free natural gas which overlies and is in contact with crude oil in the reservoir. It is a subset of associated gas
