Working in the gas energy sector my company has a weird relationship with oil politics.

On one hand gas/oil bad which should make us favor Republicans, but on the other hand... renewables and restrictions on Coal have really helped my company out. Gas turbines are really the only practical sources of peak demand with renewables. Yes I know in 30-years or so, we will be out of business unless there is a break through with Hydrogen. (New gas turbines are designed with the potential to run hydrogen)

I work maintenance on gas power plants, and we are struggling to hire enough technicians to work our outages. This October we are at 120% demand (jobs to personnel). Next spring will be our busiest year ever.

Anyway, if anyone knows young kids who want to go into blue collar technical work... there are high paying jobs!

I work in the Gulf South with pipeline / salt cavern storage. The issue with "cavern homogeneity" the Employ America piece lays out is a real concern.

While salt cavern wells can / do get deinventoried and have products swapped...product contamination is always huge concern and one of the pathways for contamination here is the "brine" utilized to empty / fill the well.

Typically in a salt cavern, you have to keep *something* in the well when it is not full of oil...and that thing is brine (salt saturated water). This keeps well from leaching out (less than saturated water from eating away at salt walls of wells in an unpredictable way). If you are storing sour crude in these wells, it's not unlikely that some sulfur contamination will contaminate your brine source / storage. Since the brine for multiple wells is typically consolidated across multiple wells, you risk contaminating a "sweet" well that is utilizing the same brine as a sour well. To manage two types of wells without risk of contamination, you likely need two segregated brine systems to reduce these odds. My educated prior is it would be easier to swap one of the four "hubs" completely over to sweet crude rather than try to swap a handful of the wells at each site.

Another additional question I had which the Employ America piece does not address. Given the historical nature of the SPR only servicing "sour crude" to refineries utilizing sour crude, it's an open question whether the pipeline connections / pathways exist such that the sweet crude can get to the reserve from all potential customers who might sell to the SPR, etc. If suddenly the hub nearest to your refinery doesn't service "sour" crude anymore, only sweet...you suddenly provide no value to the sour crude folks in the region.
