Solution Gas-Water Ratio (Rsw)

Gas-Water Ratio (GWR) means the ratio of gas produced from a barrel of produced water when cooling and depressurizing produced water to standard conditions, expressed in terms of standard cubic feet of gas per barrel of water.

The solution gas-water ratio changes as reservoir pressure changes in the same was as the oil solution gas-oil ratio.
