It was always the case that we couldn't extract the oil from them without damaging the caverns. The bottom 50% of the reserve was always going to be a one time use thing. Ideally that was for WWIII, and not protecting Israel.

Fresh water is often pumped into the caverns during rapid drawdowns, which dissolves the salt walls, Misra said. This “creates flatter, less stable roof and severely thins the critical salt pillars that separate adjacent caverns, greatly increasing the geological risk of a structural cave-in,” he said.
