>>My very basic, 15 year old geology training made me believe that these
oil-bearing deposits were ancient and "fermented to completion" if you will,
and once they were pumped dry and maybe flushed once or twice to catch the
crude that didn't come to the surface the first time, they were empty.<<
Me, too. That's what caught my eye about the abstract I read. I am trying to
locate the author and publication. I have a viedo someone lent me of one of the
3D reservoir fluid flow models generated either by that same prof or at that
same converence. Very spiffy stuff!!
>>How substantial is this recharging?<<
I asked the same question, but not in quite this nice a fashion. My tone was
… how shall we say, somewhat derisive. Perhaps jeering. It seems that the
charging is complete under the right conditions and can be accomplished in as
few as about 20 years.
>>Can you in fact go so far as to identify a formation that is aching to
produce oil or gas but has not yet done so; or to go a step further, look at a
producing formation and say, "Hmm, this may produce even better later on" or
"This one will recharge and this one won't"…?<<
Apparently so. I'm sure the model will be hotly debated, but the fact that
there's new oil in some of them thar Louisiana fields is undeniable ….
especially when someone is trucking the monetary gains from production in these
"depleted" fields to the bank.
