Petroleum and Natural gas are formed when organic matter, mostly microscopic
remains of plants (not dinosaur parts) are deeply buired by sedimentary
processes and then subjected to increasing pressure and heat with burial.
Essentially, the earth does what any good refinery does - cook stuff under
pressure. Now how long does it take? Well the answer varies. Much of the
Middle Eastern and North Shore Oils are found in geologically young (say
less than 60 million years) rocks but testing of the oil indicates that it
actually migrated there from deeper older rocks. Although there is some
variation depending upon where you are, most of the worlds oil is souced
from rocks in the range of 150-20 million years or so some a bit older, some
a bit younger. That means is takes along time to make oil.

Is oil forming today? Most certainly, but not at a time scale that will do
us any good. We are burning oil and gas at a much faster rate than it could
ever be replenished.

I used to work for Sun (old Sunoco) and they ran a large "synfuel" plant up
in the Athabaska Tar sands. The tar must be steamed off the sand particles
under pressure so it is pretty expensive to do so but at todays price, VERY
econmical. Biggest problem is that the mine has to be basically shut down
in the winter. It gets so could that the sand/tar mass becomes extremely
hard, too hard to mine without explosives and that would cost. So they
spend the warm months mining like crazy and filling big sheds with the stuff
so they can continue to produce during the winter.
Just thought I would pass on a bit of knowlege after all these years as a
Geologist. More Questions anyone? ;^)
