Glad you asked,
@the-lost-son
If you don't mind, I'll jump in and add to
@James from London and also give you the view from here in Texas.
Out here, there were the Seven Sisters and then everybody else. They consolidated so now I should say there are the Supermajors and everybody else.
The thing people don't realize is that even though there are only six Supermajors, there are thousands of smaller, independent oil companies in Texas and Oklahoma. Think companies in the show
Dallas such as Harwood Oil, Bradley Oil, Hurst Oil, Luce Oil, and of course, Ewing Oil. As you all know, I work for one of the independents here in Texas. (But not one of those).
When times are good, the supermajors pile up cash. Then when times are bad, they use that cash to buy smaller companies.
In the reunion movie
J.R. Returns, Westar was one of the Seven Sisters and Ewing Oil was one of the bigger independents, now owned by Cliff Barnes. There is a great scene in J.R. Returns where J.R. meets with Carter Mckay to try and talk him out of buying Ewing OIl.
If you watch this scene, notice how both Larry Hagman and George Kennedy each down play the scene-- just two powerful figures having a quiet conversation. Very well acted.
J.R.-- I think we should talk. About Westar buying Ewing Oil. I'm curious... Why?
Mac-- It's a good company. Ewing still has some undeveloped fields and we have the money to develop them.
J.R.-- Well assuming this acquisition does go through, what happens to Ewing Oil? Does Ewing Oil cease to exist?
Mac-- Like Jonah and the whale, we would swallow it whole.
J.R.-- You still trying to pick off the independents one at a time aren't you?
Mac-- Something along those lines.
J.R.-- Say you did buy Ewing Oil and then turned around and sold it (to me) for a substantial profit. That would be quite a feather in your cap.
Mac-- That's never going to happen. Ewing oil is simply a small part of a long range program I promised my board.
J.R. Never say never, Mac. One thing I've always admired about you is you never put promises ahead of profit.
...
After this conversation, J.R. is able to get the upper hand on Carter Mckay. J.R. lays out how well his master plan has worked. His final insult is so funny, and Larry Hagman delivers it with the perfect understated delivery:
"Don't kid yourself, Mac. Your long range program just fell on it's ass."
HAHAHAHAHA! I'd encourage you to use that line whenever you can. I do.
