How this was calculated
CGR: Condensate-gas ratio = condensate rate (bbl/d) / gas rate (Mcf/d) * 1000 = bbl/MMcf. Typical range: 5-300 bbl/MMcf.
GOR: Gas-oil ratio = gas rate (Mcf/d) / condensate rate (bbl/d) * 1000 = scf/bbl. Inverse of CGR.
BOE: Barrel of oil equivalent = condensate (bbl/d) + gas (Mcf/d) / 6. The factor of 6 is the standard energy-equivalent conversion (6 Mcf gas ~ 1 bbl oil).
Gas classification: Dry gas: CGR < 10 bbl/MMcf. Wet gas: CGR 10-50. Gas condensate: CGR 50-300. Volatile oil: CGR > 300.
NGL yield: Natural gas liquids recovered at the processing plant, typically 10-50 bbl/MMcf for rich gas.

The condensate-gas ratio (CGR) is a key parameter that characterizes gas-condensate reservoirs and determines their economic value. It represents the volume of liquid hydrocarbons (condensate) recovered per unit of gas produced. A higher CGR means more valuable liquids per unit of gas, significantly impacting well economics since condensate typically sells at a premium to dry gas.
Gas classification based on CGR helps engineers understand the reservoir fluid system. Dry gas reservoirs (CGR below 10 bbl/MMcf) produce essentially no liquids. Wet gas systems (10-50 bbl/MMcf) produce some liquids at the surface but remain single-phase in the reservoir. Gas-condensate reservoirs (50-300 bbl/MMcf) can experience retrograde condensation below the dew point, where liquid drops out in the reservoir, reducing productivity and recoverable liquids. Volatile oil systems (above 300 bbl/MMcf) behave more like oil reservoirs with high gas content.
BOE (barrel of oil equivalent) provides a common unit for comparing oil and gas production. The standard conversion uses 6 Mcf of gas = 1 barrel of oil on an energy-equivalent basis. However, the economic equivalence depends on current commodity prices and may differ significantly from the energy equivalence.
