The common unit for measuring petroleum, including heavy oil. One barrel contains approximately 159 L.

Equipment to process or store crude oil from one or more wells.

Is a heavy, viscous form of crude oil, bitumen general has an API gravity of less than 10°. Also called tar sands or oil sands, shares the attributes of heavy oil but is yet more dense and viscous. Na [..]

a temperature scale that registers the freezing point of water as 0° and the boiling point as 100° under normal atmospheric pressure. Room temperature is between 20° and 25° degrees celsius.

Is a production technique where the oil is simply pumped out of the sands using specialized pumps such as progressive cavity pumps.

Crude oil that flows naturally or that can be pumped without being heated or diluted.

A cylindrical sample taken from a formation for geological analysis.

Oil which has not undergone any refining. Crude oil is a mixture of hydrocarbons with small quantities of other chemicals such as sulphur, nitrogen and oxygen. Crude oil varies radically in its proper [..]
