Recent Developments in Underground Storage Techniques

SUMMARY: Changes in the energy situation, as well as safety aspects, have caused new and more stringent demands to be made for the storage of oil. It will become necessary to put an increasing share of the oil storage underground. However, conventional methods for storage of oil, on waterbed in unlined caverns, are not sufficient for all types of products. Vertical, cylindrical caverns can provide better storage conditions for oil products. Simple calculations show that from a rock mechanical point of view, such caverns are preferable because the cylindrical wall and the dome or cone-shaped roof provides more favourable stress conditions at the contour.
