It turns out that in the end I wrote some 929 posts on The Oil Drum, over the course of its eight-year life, 92 of them in the past two years. The posts covered the gamut from how coal mines work, to some of the innovative work being done in Saudi Arabia to extend the life of their reservoirs – sometimes straying a little from a tight focus on fossil fuel extraction but rarely for long. As I noted in last week’s post (which ran a week later on The Oil Drum as my swan song there) the audience that the site brought far exceeded any that I had during the totality of the students that sat in my classes over 40-years of teaching (a number in the low thousands).

My hope in writing was to provide a little background to some of the stories that made the news and to put some of the developments in context, so that readers might better understand. One of the most useful sources for this was always Leanan’s Drumbeat, and as this now too fades into an archive, let me pick an example from the penultimate Drumbeat as the basis for this week’s post.
