High Gas-Oil Ratio (HGOR)

Definition - What does High Gas-Oil Ratio (HGOR) mean?

High Gas-Oil Ratio is a large ratio of the amount of gas to crude oil produced when hydrocarbons are being extracted from a reservoir. This is generally related to associated gas (AG) or saturated gas, also known as a solution gas which is dissolved in the crude oil. It is represented as standard cubic feet per stock tank barrel (scf/stb). High Gas to Oil Ratio is abbreviated as HGOR.

Petropedia explains High Gas-Oil Ratio (HGOR)

If the Gas-Oil Ratio in the crude oil that is being produced is high, such crude oil is considered as a precious commodity as it will yield higher trade value. Generally, the high Gas to Oil ratio is observed in light crude oil as heavy crude oil has low API Gravity and thus has low capacity of containing associated gas or solution gas.

High Oil to Gas ratio also proves to be a good factor in determining the category of crude oil as Light or Heavy Crude oil production from a well. It also helps analysts to determine how much gas is produced along with the crude oil. More specifically, gas to oil ratio is the amount of gas produced from hydrocarbon solution to the volume of oil at standard conditions.
