Gosh, for a bit there, I was feeling like part of an all-powerful

There may be a way to get the fuel out using bacteria, but we still
have to make sure to put more carbon back.
Bacteria: Turning tar sands into natural gas
Dennis T. Avery
Avery is a senior fellow for the Hudson Institute in Washington,
D.C., and is the director for the Center for Global Food Issues.
Scientists said recently in the journal Nature they can radically
speed up the underground bacterial fermentation that turns Canada's
tar-like Athabasca sands into natural gas at far less cost and with
far less environmental pollution.
This is huge global news because the world has about 6 trillion
barrels of such heavy oil, more than 20 times the proven oil reserves
in Saudi Arabia. They're focused in Canada's Athabasca, in
Venezuela's Orinoco tar belt, and in the oil shale of the U.S. Rocky
Mountains. All may be economically recoverable with bacterial refining.
Dr. Steve Larter of the University of Calgary says understanding how
anaerobic bacteria ferment heavy oil into clean-burning methane
underground opens the door to recovering the gas from deeply buried
oil sands.
"The main thing is you'd be recovering a much cleaner fuel," he says.
"Methane is, per energy unit, a much lower carbon dioxide emitter
than bitumen."
A separate family of microbes that produces CO2 and hydrogen from
partly degraded oil offers a way to capture the CO2 from the tar
sands as methane, for burning in a closed-loop system would keep the
CO2 out of the atmosphere.
Larter's research team combined microbiological studies, lab
experiments and oil field case studies to demonstrate the anaerobic
degradation of oil into methane. The findings offer the potential of
"feeding" the microbes and rapidly accelerating the gas production
process. Says Larter, "Instead of 10 million years, we want to do it
in 10 years. We think it's possible. We can do it in the laboratory.
The question is can we do it in a reservoir?"
No longer would huge diesel shovels have to dig up three tons of sand
for each ton of heavy oil recovered. Nor would refiners inject
expensive steam to liquefy the heavy oil so it can flow to the
surface. With bacterial refining, the tar and the contaminating
sulfur can be left deep underground -- along with most of the sand.
The oil-eating bacteria have been used for some years to clean up
contaminated soils and lagoons near oil refineries. Lab results have
been encouraging, and the team expects to do field tests as early as
2009.
At almost the same moment, a Penn State professor said drilling newly
feasible horizontal gas wells across the Marcellus black shale in
northern Appalachia could earn the U.S. $1 trillion worth of
additional clean-burning energy. The rock deposits run from southern
New York westward through Pennsylvania into West Virginia and Ohio.
Dr. Terry Engelder says the vertical fractures in the Marcellus shale
can't effectively be tapped with vertical wells. A horizontal well
costs three times as much, but can collect gas from dozens of the
fractures. He says the horizontal wells could bring in 50 trillion
cubic feet of gas, the equivalent of a Super Giant gas field.
Eco-activists have been telling us we should renounce fossil fuels
because they're nearly gone anyway. However, the U.S. has centuries
worth of coal that could be burned in "clean" high-tech systems.
Bacterial refining and Engelder's horizontal drilling offer other
examples of high-tech energy. Cambridge Energy Research Associates
predicted in June that world oil production would rise another 30
percent by 2017, with nearly half of the increase from unconventional
sources such as natural-gas liquids.
[CERA's reputation is very low among Peak Oil writers. They do not
see how a 30% increase can be achieved, or even much less increase.
Geo.]
Man-made global warming alarmists have failed to offer any cost-
effective substitute for coal, oil and nuclear in base-load energy
production. Solar and wind power are costly and erratic. Biofuels
take too much land away from nature. The problem is to bridge the
energy gap between today and some as-yet-unproven energy technology
for humanity's future.
Best,
