Since 1981, Shell researchers at the company's division of "unconventional resources" have been spending their own money trying to figure out how to get usable energy out of oil shale. Judging by the presentation the Rocky Mountain News heard this week, they think they've got it.
Shell's method, which it calls "in situ conversion," is simplicity itself in concept but exquisitely ingenious in execution. Terry O'Connor, a vice president for external and regulatory affairs at Shell Exploration and Production, explained how it's done (and they have done it, in several test projects):
Drill shafts into the oil-bearing rock. Drop heaters down the shaft. Cook the rock until the hydrocarbons boil off, the lightest and most desirable first. Collect them.
Please note, you don't have to go looking for oil fields when you're brewing your own.
On one small test plot about 20 feet by 35 feet, on land Shell owns, they started heating the rock in early 2004. "Product" - about one-third natural gas, two-thirds light crude - began to appear in September 2004. They turned the heaters off about a month ago, after harvesting about 1,500 barrels of oil.
More on the technique, and Shell Oil's next steps (Shell has applied for an R&D lease on 160 acres of Bureau of Land Management land, which could be approved by February. That project would be on a large enough scale so design of a commercial facility could begin.) Engineer, techie and finance types should go read the whole thing. |
