One of the challenging "things" about the blog is how to update older posts. Actually, that's not the problem. It's easy to update older posts. The problem is that some really great updates are lost to readers. I post 5 - 10 posts/day (sometimes more) and update even a larger number of older posts every day.
A few moments ago I updated an earlier post that I think readers will enjoy: a reader sent in an "explanation" of the rigs and the wells that were "featured" in one of the incredible photos that Vern Whitten sent yesterday.
This is the post.
