Microbial Injection

I know this has been around for a couple of years, but does anybody have experience with this technique. I imagine it only works for shallow reservoirs, based on reservoir temperatures and pressure. What temperatures and pressures can these microbes withstand? And what is the story between hydrogen production. i heard about that on some convention 2 years ago as being a rather new technique, which would also solve CO2 emitting problems. Has this been used since then? Any case studies.

Would appreciate input into the discussion here...

you can throw the bugs and the food and close in the well. pressure buildup is slow, but it works in dead wells that can not be shut in.
