Investigation on physical and mechanical properties of interlayers in bedded salt deposits and their effects on storage caverns
Because of anisotropy and inhomogeneity arising from the presence of non-salt interbeds, construction and operation of gas storage cavern in bedded salt deposits are singularly challenging. In this paper, physical and mechanical properties of common interlayers in bedded salt deposit are discussed. Large behavioral differences among lithologies (shale, mudstone, anhydrite, and dolomite) exist: anhydrites are generally very strong, mudstones can be very weak, and both are common interbeds in bedded evaporites. Based on analysis and experience, we propose four basic issues that must be addressed to estimate operational pressure limits in bedded salt deposits. These issues are the wellbottom tightness, general cavern tightness, cavern roof stability, and flow control.
