SPR is stored in salt caverns with the pressure of the crude oil replacement brine keeping the cavern walls & ceilings structurally intact.
But brine is denser than crude. So the higher the ratio brine/crude, the lower the pressure, the higher the risk of salt creep and ultimately salt falls which is collapse of walls/ceilings.
Every collapsed cavern traps the remaining crude. It's no longer possible to pump out crude and pump in brine.
So it doesn't matter to what degree Trump is mentally unbalanced or mentally ill, because past a certain point, depletion will trap the remaining crude.
Estimates are at 140-150 MMbbl the risk of wall collapse is extreme.
But we have another limit which is flow velocity.
At full capacity 715 MMbbl, max flow is 4.4 MMbbl/d
Currently at 350 MMbbl, max flow is substantially lower, perhaps 2.8-3.1 MMbbl/d.
For 200-300 MMbbl max flow drops down to range 1.9 - 2.5 MMbbl/d.
At 150 MMbbl max flow drops sharply below 1 MMbbl/d.
Note that 243-252 MMbbl statutory & strategic limits kick-in that a president can not easily override.
Keep in mind that primary purpose of SPR is response to natural disasters such as severe winter snowstorms/blizzards, tornadoes, hurricanes, floods, earthquakes, wildfires. This is where the max flow is needed.
So depleting SPR below 300 MMbbl is playing with matches & gasoline, not because we're running at 1.1-1.3 MMbbl/day, but because our max flow is no longer an adequate response to natural disaster emergency need for fuel.
