A small FYI. I believe Shlumberger(SLB) recently bought the rights to the Raytheon developed Microwave technology. SLB has given no indication of what it plans to do with it or when.

The Schlumberger microwave story can be found in Oilweek here:

And in the International Herald Tribune Here:

From Oilweek:

Much as a microwave oven heats food, Raytheon Co.‘s (NYSE:RTN) technology relies on microwaves to generate underground heat and melt a waxy substance in the shale called kerogen so it can be converted into oil.
