The ratio of gas to oil is set by the engine manufacturer but ranges from 30:1 to 50:1 per volume unit. Oil remaining in the mixture is burnt with the fuel and results in a familiar blue smoke and odor. R sfb = bubble-point solution gas/oil ratio as defined by equation (5-202), scf/STB. R sdb = solution gas/oil at the bubble-point pressure as measured by the differential liberation test, scf/STB. R sd = solution gas/oil ratio at various pressure levels as measured by the differential liberation test, scf/STB To account for solution gas, petroleum engineers have defined a solution gas ratio (). The solution gas ratio is defined as the number of standard cubic feet of gas which will dissolve in one stock tank barrel of oil when both are taken down to reservoir pressure. this value. The majority of the published bubblepoint solution gas/oil ratio correlations are functions of. bubblepoint pressure and gas gravity, which can be obtained either experimentally (pressure-volume-. temperature, PVT analysis) or estimated from the existing correlations. 2. n. [Production] The ratio of the volume of gas that comes out of solution to the volume of oil at standard conditions. Once OOIP is determined, Solution Gas in the original oil can be estimated by the following equation: Gsi = OOIP x Rsi. Where, Gsi = Solution Gas in the original oil (scf or MMscf) Rsi = Solution Gas to oil ratio (scf/stb) The above calculations need to be performed with the assumption that there is no gas cap on the oil reservoir. The gas-liquid ratio is the ratio of a volume of gas divided by a volume of liquid at the same temperature and pressure. The gas-liquid ratio, or GLR, is useful for characterizing the behavior of a reservoir. The choice of GLR depends on the fluids in the reservoir.
