Principles of underground storage |
 |
Oil and water can be kept separate through differences in specific gravity |
|
Oil and gas leaks can be prevented using aquifer water pressure in the bedrock |
|
| |
|
Ensuring gas sealing |
|
Adjusting of permeability through grouting and shotcrete |
|
Hydrodynamic adjustment through the water curtain system |
|
