Gas-Oil Ratio (GOR)
Definition - What does Gas-Oil Ratio (GOR) mean?
Gas-Oil Ratio, abbreviated as GOR is the volume of gas that is produced from crude oil when the oil is being extracted from the reservoir to the earth's surface through production tubing. This is generally related to associated gas (AG) or saturated gas in the oil reservoir. The gas is represented as standard cubic feet per stock tank barrel (scf/stb).
Petropedia explains Gas-Oil Ratio (GOR)
When crude oil is produced from an oil well, natural gas known as associated gas may also be extracted along with the oil. A gas to oil ratio is calculated which lets the analysts know how much gas is produced along with the oil. More specifically, gas to oil ratio is the amount of gas produced from hydrocarbon solution to the volume of oil at standard conditions.
The associated gas is the natural gas that is dissolved in the oil and is produced along with the crude oil. Heavy crude oil has low API gravity and low capacities of dissolved gas as compared to lighter crude oil.
