  • Method for recovering gas from solution in aquifer waters
    Patent number: 4149596
    Abstract: In a method for producing hydrocarbon gas from aquifers which contain gas in water solution, water is produced from wells distributed through the aquifer and solution gases are recovered from the produced water. The aquifer pressure declines as production continues; gas comes out of water solution and a gas phase saturation builds up in the aquifer. When gas saturation exceeds a critical value, gas in gaseous phase flows through the aquifer rock to the producing wells and the ratio of total gas to total water produced increases substantially.
