It's amusing that people have this misguided idea that we'll simply 'invent' our way out of the energy crisis with technology, and life in America will just go on, flexible and fancy-free. They seem to forget that technology requires energy, unless we want to revert back to pre-20th century 'technology'. That home price chart is pretty telling. It tells me that I'm gonna have a helluva time trying to sell my house in order to leave CO and be with my girlfriend anytime soon... ![]() |

for those who are interested in the details of the Shell oil shale project, here's another link to the plan of operations pdf submitted to the BLM (dated 2/15/2006): http://www.blm.gov/content/etc/media...Operations.pdf Shell's plan for extracting oil from kerogen rich shale in the Piceance Creek basin of Colorado is an exciting idea blending innovative technology with plain old organic geochemistry. It's simply heating the rock in-situ to between 550 and 750°F for two years and then pumping the oil out, essentially completing the process that nature had not quite yet finished. Quoting the BLM on oil shale reserves: "More than 70 percent of American oil shale — including the thickest and richest deposits — lies on federal land, primarily in Colorado, Utah, and Wyoming. These federal lands contain an estimated 1.23 trillion barrels of oil — more than 50 times the nation's proven conventional oil reserves." the viability of the project rests with Shell's projected EROEI, or Energy Returned on Energy Invested, of 3 to 4. the Canadian Athabasca tar sands, in comparison, have an EROEI ranging from 1.5 to 2. Shell believes their oil shale extraction technology could be competitive with oil prices above $30/barrel. bottom line, the recoverable reserves work out to 1 million barrels recoverable oil per acre or 1 billion barrels per square mile times 1,000 square miles of the richest oil shale (Mahogany Ledge or Zone), yielding 1 trillion barrels oil. pie in the sky? maybe. but the next step, a commercial level project beginning by 2010, would determine if the predicted EROEI and oil yields could be sustainable over the long haul. again, according to Shell's estimates, if they incrementally process 23 square miles of the richest oil shale and maintain a daily production rate of 3 mbopd, the project could ultimately yield 15 billion barrels oil over a 40 year life. Prudhoe Bay, the largest oil field in North America, in comparison, contains 25 billion barrels oil. the Shell process is not science fiction, it's doable now. and possibly by the end of this decade, it could add up to an extra 3 million bopd entirely from Colorado. read the Shell pdf, specifically section 4.4 Recovery Efficiency and Energy Balance, which explains the economics of how 1 btu energy in provided by electrical power could result in 3 to 4 btu's energy out from the produced oil and gas in the shale. hey, maybe we do have technology, dude! ![]() |

I have to agree that oil shale will never be a significant source of energy for the US, and I've spent a lot of time in "shale country." The problem with shale is that, despite a century of trying, no one has been able to figure out how to produce oil (actually kerogen) from it without expending nearly as much energy as is contained in the shale itself. A friend who worked in the synfuels industry in the 1970's explained to me that the higher energy prices go, the higher the cost to produce the petroleum from shale gets--the lines of cost vs. income never cross to make the process profitable. When the federal government pulled subsidies from oil shale in the early 1980's, "Black Sunday" in 1982 was the direct result. Exxon made way more money turning their development at Parachute for oil shale employees into a retirement-type development than they ever did in the oil shale business.
The best hope for synfuels is much simpler and much more direct than oil shale--it's coal liquification; that is, making diesel fuel and other distillates out of coal. That technology is already available and coal has much more concentrated hydrocarbons than oil shale. Even that technology is yet to be used on any significant scale in the US, but I predict that it will be--and that will leave oil shale development in the dustbin of history. We Americans need to get over "wishing" for some magic bullet of cheap energy to save our sorry ***es from having to modify our overconsumptive, auto-dependent lifestyle. The era of cheap, plentiful energy is OVER, and the sooner we accept that, the sooner we can go about keeping this country relatively comfortable and livable within the constraints of that new reality. Otherwise, the US is likely not to be either very comfortable or very livable. |

why my interest in oil shale (and no one in the oil biz calls it "kerogen marlstone" btw)? i spent a stint in the middle 70's as a geologist with Exxon Minerals (before moving on to their oil and gas company) mapping the Mahogany Ledge on the surface and subsurface in the Piceance Creek basin. so, yeah, i kicked around nw Colorado for a while and you might say i know something about the geology of the area. Exxon's vision was to strip mine the richest part of the basin, cooking billions of tons of rock in massive sized retorts requiring equally massive amounts of electricity and water, and dumping the toxic heavy metal laden tailings back in the hole created by mining. it was doomed from the beginning because of a marginal EROEI and the saudis threatened production increases (defending their market share) at nearly opec meeting. i suggested instead a in-situ approach similar to Shell's ICP, but got voted down by management and the senior engineers because it wasn't "grand" enough for Exxon and their shareholders. ultimately Exxon abandoned the program in the early '80's because management decided that developing their Natuna field in Indonesia (S China sea) had a higher upside than shale oil. they were right. Natuna is the largest gas field in the world with 222 TCF gas in place and 46 TCF gas recoverable. end history lesson. some important points about the Shell process: the oil produced is 38 gravity crude and can be processed by any refiner in the country. two, the electrical expenditures predicted by RAND are way too pessimistic, but as expected by a peak oil biased report, hence the need for a commercial scale project to get accurate costs. three, in-situ means minimal land disturbance or no more than what is necessary for a multi-well oil field with enhanced recovery operations. four, formation and surface waters would be reprocessed and reused in the extraction operation. the water requirements for this process are much lower than those used by retorting. five, alternate energy sources, such as geothermal and wind power could be used instead of coal or gas fired power plants. Quoting from Xcel Energy website: "As of early 2007, we had 1,323 megawatts of wind energy capacity in service. We expect to have 2,600 megawatts in service by the end of 2007 and 6,000 by 2020." Colorado is rich in unexploited geothermal energy that can be converted into electricty. so there's more than enough usable electricity available generated from alternate but now conventional sources. conclusion? wait and see in 5 or so years who's right and who ain't... ![]() |

I absolutely agree that the "Shell" process has much more promise than the grandiose Exxon gambit of nearly three decades ago. My view, however, is a more macro one. Our petroleum-reliant infrastructure was built initially when getting oil in the US was not much more than punch a hole in the right place and pump the oil out (some places it would even flow on its own). There are still quite a few of those relatively cheap-to-produce-oil fields out there in production, but they are obviously in decline and it's highly unlikely we will find any more like that. In the last 30-50 years, oil production has moved to more and more of a) figuring out how to wring the last drop of oil out of a field; or b) drill for conventional oil in more and more difficult and remote places; or c) import it from places where cheap-to-produce oil is still found. If one reads the EIA reports for any length of time, it's clear that much of the US supply is now coming from option "c)" Now, I don't happen to think that reliance on that much foreign oil is a good idea, especially since those "easy" fields are clearly now in decline, too. Not great, either, that much of that oil is located in countries that happen to hate our guts. So, the relatively new option "d)" is to figure out how to produce oil from "non-conventional" sources, oil shale being one.
There is only one little itsy-bitsy problem with that (actually it's a HUGE problem): Our current lifestyle in the US depends on copious quantities of CHEAP petroleum. Even if oil shale is wildly successful, the oil produced from it will be anything but cheap--and, all the while, those older "cheap" sources of oil production in the US and around the world will be depleting. So, regardless of whether or not shale or other non-conventional (read: expensive to produce) oil production happens, I stand by the last sentences of my prior post: Quote:
