Gas-oil ratio in m³/t at normal conditions
Converts the gas content of reservoir oil from m³/m³ to m³ per tonne at normal conditions (0 °C).
Gf₀ = 1000 × Gf / (ρo × T₂₀ / T₀), T₂₀ = 293.15 K, T₀ = 273 KInputs
You can change a field's unit: the value is converted to the formula's units automatically.
