He's right then.  I never heard of Xcel. I left the USA in 1990 and there's been a lot of takeovers since then, but I do remember Colorado Interstate Gas and most of their immediate supply wells were in the Tx-Ok panhandles and SW Kansas.  Those were the old gathering systems in which I was trying to turn one around to supply a proposed peak generator in Larime Co.  They were some producing wells still left around that particular area, but they were on their last breath 16 years ago and were running at about 30-40% N2, so even then they wern't what you would call star performers.
But he's still wrong about having hundreds of glycol treaters.  There's only a couple of those per field.
Xcel used to be called Public Service Company.
The only XL that I heard about before was Microsoft's.  I'm surprized they don't sue Excel for some name infrigement violations.-)
