remaining established reserves of conventional crude total 593 million cubic
metres, or 82 percent of Canadian on-shore reserves. Production from
conventional sources totaled 57.2 million cubic metres in 1998.
decline, greater efforts are being made to improve production from existing reservoirs. Water injection, or secondary recovery, is the most common enhanced
oil recovery (EOR) technique, but increased attention is being given to advanced
or tertiary methods, such as miscible flood (injecting natural gas liquids
which act as a solvent), to recover additional oil.
More than 45 EOR
projects operating in Alberta in 1988 were credited with producing an additional
18.3 thousand cubic metres per day.
