The Oil Drum: Carbonates are not a drink

For those new to this site, on Saturdays I often post a ‘techie’ talk which is going through the process of drilling an oilwell, and explaining some of what goes on. It was in part motivated to give a scientific explanation for the depletion that Matt Simmons and others discuss elsewhere.

Since these are getting a bit long in number, I will now start pasting the sites of earlier entries (which largely dealt with drilling the well) at the end of the post, rather than the beginning. And I again emphasize that, life being what it is, the true situation is often a bit more complex than I describe in this simplistic overview.
A lot more techie talk after the jump at The Oil Drum.
