On the acoustic attenuation characteristics of sonar detection in the salt-cavern gas storage environment

Frontiers in Earth Science, 2023
Aiming at the acoustic attenuation in the salt-cavern environment, this paper established a theoretical relationship of the ultrasonic attenuation in the salt-cavern gas storage, based on the wave equation of the acoustic wave propagating in a non-ideal ...

A salt cavern abandonment test

International Journal of Rock Mechanics and Mining Sciences, 2001
Thousands of caverns have been leached out from deep salt formations. They are used for saturated brine production and/or hydrocarbons storage. They will be abandoned some day: the access well will be plugged with cement, isolating a large bubble of saturated brine.

Heat transfer in salt caverns [PDF]

International Journal of Rock Mechanics and Mining Sciences, 2019
Abstract Several aspects of the thermodynamic behavior of salt caverns containing brine, oil, natural gas, air or hydrogen are discussed. It is shown that natural convection always appears in a liquid-filled cavern. This is not true in the case of gas caverns.

Stability analysis of double-cavity salt cavern storage with reasonable pillar width

You-qi chuyun, 2021
Salt cavern gas storage is an important facility for storage and peak-load sheaving of natural gas. In order to analyze the effects of pillar width on the stability of double-cavity salt cavern storage, by taking Jintan Underground Salt Cavern Storage as

Physical simulation experiment on horizontal docking well leaching for salt cavern storage

You-qi chuyun
Objective Horizontal docking well leaching is prevalently applied among salt chemical enterprises for brine extraction. However, controlling the cavern shape becomes challenging when this technique is utilized, primarily due to the absence of dissolution
