Abstract
Groundwater control is a means of ensuring that no gas leakage occurs from unlined rock storage caverns. To achieve a better understanding o f the principles of gas containment under groundwater and how to obtai n maximum gas storage capacity, analyses of groundwater conditions sur rounding storage caverns and the effects of different factors on gas s torage capacity have been performed and are reported in this paper. Th e analysis results indicate that the critical gas pressure of a storag e facility is considerably less than the natural hydrostatic pressure around the caverns and somewhat less than the water curtain pressure. High gas storage capacity can be obtained by optimizing the design of cavern configuration, water curtain layout, cavern depth, etc. The pri nciples of such optimization are outlined in this paper.
