Going after next oil sands frontiers
Friday, 09, April 2010
The decades-long drive to liberate more of the commercial value trapped in Alberta, Canada’s bitumen-bearing deposits without exacerbating the industry’s “dirty oil” image has given rise to a bewildering array of mostly-unproven technologies. Some are barely beyond the concept stage, some are still in the lab phase and some are moving to field tests, demonstration projects and pilot operations as companies jostle each other to open the door to mind-boggling riches that are more than double the 172 billion barrels currently considered to be economically recoverable.
Next in the line-up of untapped deposits is the Grosmont carbonate, which occupies the vast space between the Fort McMurray and Peace River oil sands regions in northeastern and northwestern Alberta.Unlike the more conventional oil sands deposits, where bitumen is trapped between molecules of water and grains of sand, the Energy Resources Conservation Board of Alberta estimates Grosmont holds an additional 320 billion barrels of resource encased in limestone in a structure underlying the Athabasca deposit that fuels today’s oil sands industry.
