Debolt formation water contains sour gas in solution. When depressurized to atmospheric conditions, the Debolt water flashed off sour gas at a gas water ratio of 1.35 standard m3 of gas to 1 m3 of water. The flashed gas contained 0.5% H2S (hydrogen sulphide), 42% CO2 (carbon dioxide) and 57% CH4 (methane). These gases are the same gases present in shale gas production wells, which are normally in the range of 0.0005% H2S, 9% CO2, and 91% CH4, and the use of raw Debolt water would have a negligible impact on the current percentage of shale gas components.
