Alberta's oil reserves are sourced in the following ways: by strip mining shallow bitumen sands deposits, where 90% recovery of original oil-in-place is achieved; by in situ extraction of bitumen sands in deeper deposits using cyclic steam stimulation, now achieving recovery factors of 35% to 40%; by steam-assisted gravity drainage, typically achieving recovery factors exceeding 50%, and sometimes up to 70%; by in situ extraction of bitumen carbonate deposits, where two successful commercial-scale pilot projects in the Grosmont deposit are now both proceeding to full scale-development; and by multiple fracking of horizontal wells in tight oil shales containing a large oil resource little developed as yet, but classed as “prov ...[+++]ed undeveloped”, based on success exploiting analogous tight oil shales in the U.S. These recent developments and improvements in recovery factors indicate Alberta's proved oil reserves are 848 billion barrels.
