 For conventional heavy oil, the industry is exploring new zones in undrilled portions of the basin to find remaining undiscovered pools, or to apply EOR schemes such as water floods, thermal projects, and miscible floods such as the Vapour Extraction Process (VAPEX) technology.Only 15 percent of heavy oil is currently being recovered, leaving a large volume for future recovery.Improved seismic and drilling technology, higher recoveries from existing pools through infill drilling, and efficient, cost-effective exploration and development of smaller pools are maintaining levels of conventional oil production in the Western Canada Sedimentary Basin.
