The Scarcity of Hydrochloric Acid — Anyone Have a Clue What May Be Going On?

The scarcity of hydrochloric acid has slowed up the drilling of some oil wells here locally in the Tulsa area.  As many of you already know or not, hydrochloric acid is critical to the oil industry as well as to the dairy industry.

Hydrochloric acid is used to clean tanks, lines, and containers in the production of oil and milk.  In the oil fields hydrochloric acid is used down hole to clean out the zones.

Evidently several of the plants that produce hydrochloric acid have recently gone out of business, claiming force majeure.  Suppliers are scrounging for product to sell to their regular customers.

Now, I don’t know of any recent natural disasters or political upheavals here in mid-America that would be interfering with the production of hydrochloric acid.

Does anyone know what is going on?  I know I live in a bubble, but this question has me stumped.  What am I missing here?
