Yang et al. (2015) study the feasibility of using abandoned salt caverns for large-scale underground energy storage using by 3D geomechanical numerical simulations. The performed has been an overview is presented of the geology of the site, mechanical parameters interface between rock salt and
interlayers, permeability of the rock salt are. The results indicate that the maximum volume shrinkage of the cavern is less than
25% and the maximum deformations of diameters after operating are less than 2% for 20 years. It is recommended that the weighted average internal gas pressure be maintained as 11 MPa. Safety factors decrease with operating time, especially those of the interface between rock salt and mudstone layers decrease significantly. Effective strain is generally greater than 2%, and locally is greater than 3% after operating 20 years. The maximum pressure drop rate should be kept to less than 0.55 MPa/day and cavern walls did not collapse, nor suffer large deformation. The evaluatethe feasibility of salt cavern gas storage facilities in Jintan. can provide a reference for the implementation of similar projects in other places.
