Thackney did marvelous post on the relative costs of producing oil at various oil fields around the USA. We both searched for it. But never found it.
Yeah, that’s a pain. I had the same trouble with a topic about Carian tombs, and when I finally did find it (oddly, the search hit was a link TO the topic from another topic) I just added some better keywords, and perhaps also added it to my too-big links page.
How old was it?
