摘要
Natural gas dissolved in saline ground water can be recovered for use. The process includes the pumping of water production wells, separation of gas and water at the surface, gas compression, desalination of ground water, and injection of excess water into disposal wells. A definitive test of the process was completed on Jan. 9 and 10, 2013, at Gill Ranch Gas Field, California: volumes of recovered gas were equal to predictions based on methane solubility. Analyses of the gas showed that it was equal in heat value (about 975 BTU per cubic foot) to dry gas produced from the same field. Saline water recovered during the full scale test was returned to the same aquifer from which it was produced.
