Glenn Morton,

Three questions, if I may:

1. I recall from somewhere that the south China Sea has not been explored
much. Where, if any, are the places on earth that have yet to be

For instance, this Vermont-sized country of Belize on the southern Yucatan
peninsula has not a single oil well, while eastern Mexico has many oil or
gas wells.

2. Is politics a factor in keeping exploration from places with potentially
large discoveries?

3. As I recall, M. King Hubbert's production-rate curves looked symmetrical,
like a bell curve. The rates took as long to reach the peak as to decline.
Is this because the curve was simplified for analytical purposes, or is
there some reason other than high differential pressure that keepa a new
well from reachin the peak flow rate for a while?
