Gas-Oil Ratio

gas-oil ratio

[¦gas ¦ȯil ‚rā·shō]
(petroleum engineering)
Approximation of oil-reservoir composition, expressed in cubic feet of gas per barrel of liquid at 14.7 psia and 60°F (15.6°C).

Gas-Oil Ratio

 

the ratio between the amount of gas (in cu m) obtained from a deposit through a well, reduced to atmospheric pressure and a temperature of 20° C, and the amount of petroleum (in tons or cu m) extracted at the same time under the same pressure and temperature. The gas-oil ratio depends on the proportions of gas and petroleum in the stratum, the physical and geological properties of the stratum, the type and rate of operation, the pressure in the stratum, and so on. The gas-oil ratio is an important indicator of the expenditure of reservoir energy and the determination of gas resources in a petroleum deposit.

In order to enhance oil production and the gas-oil ratio, Saudi Aramco selected GE for agreements totaling nearly $500 million to supply a broad range of equipment and services for an expansion of the Shaybah gas-oil processing facilities.
While designing such projects especially in case of gas injection processes, solution gas-oil ratio is increased, as a result of which oil density as well as its viscosity decreases.
The new expansion is expected to enable Saudi Aramco to further increase crude production to 1 million bpd and increase the gas-oil ratio (GOR) of the field from 1,800 to 7,200 standard cubic feet per stock tank barrel (scf/stb).
The new expansion is expected to enable Saudi Aramco to further increase crude production to one million barrels per day and increase the gas-oil ratio (GOR) of the field from 1,800 to 7,200 standard cubic feet per stock tank barrel (scf/stb).
The amount of gas in the oil is referred to as the solution gas-oil ratio ("GOR"), measured in cubic feet per bbl.
The amount of gas in the reservoir fluid is usually expressed as the gas-oil ratio, GOR, and is mainly given in U.
Oil viscosity is a strong function of many thermodynamic and physical properties such as pressure, temperature, solution gas-oil ratio, bubble point pressure, gas gravity and oil gravity.
In May, it announced that its Miran West-1 well had yielded test flow results of 10,000-15,000 bpd per well of medium gravity low-sulfur crude with a low gas-oil ratio and no water.
However, taxes cannot account for the entire path of the gas-oil ratio and, in particular, for the recent downward trend.
This new expansion project is expected to enable Saudi Aramco to further increase crude production to 1 million bpd and increase the gas-oil ratio (GOR) of the field from 1,800 to 7,200 standard cubic feet per stock tank barrel (scf/stb).
The crude oil gravity is around 32 degrees API with a gas-oil ratio in line with other discoveries in the area.
This well tested 2,900 barrels of oil per day of 37-degree gravity crude, with a gas-oil ratio of 290, from a single zone at 3,021 feet.
