The poster from the other thread wrote, "Many of these are
again inside sealed lines and would require major renovations to test and replace components. " I don't know what he is talking about. It is a basic principle of good engineering to place instrumentation and control in accesible locations for maintenance and repair. Of course some sensors for temperature, pressure, etc. are inside sealed lines, but these are just sensors and not the primary control devices.

Here is another example that this guy's off base. "Also, when a well goes down, for the length's of time like in Y2k... chances are new wells will have to be drilled to get back to the oil, especially if it is an old well that was using water injection techniques. So wells are extremely vulnerable to shut downs." Water injection wells are separate from producing wells. I seriously doubt any wells being shut down for Y2K.

As for his assertion that crude solidifies below 40 Deg. F., I think this would happen for only a small part of crude produced. I worked for a large E&P company in the Gulf Coast region and we had only one small field that required heated tanks.

Perhaps someone more familiar than I about refinery operation could comment on the situations he postulated.
