Tar sands, tight oil, and other so - called «new» sources of oil are significantly more difficult and expensive to extract than
conventional liquid oil.

conventional oil reservoirs, but has not been widely applied in the production of
liquids from shale formations.
Production of
conventional crude
oil — the black
liquid stuff that rigs pump out of the ground — probably topped out for good in 2006, at about 70 million barrels a day.
It is very possible (probable in fact) that we will face a peak in
conventional oil output with a simultaneous increase in total
liquid fuel availability.
The reality of reaching peak global production of cheap,
conventional light, sweet crude
oil supplies will continue to force strong upper pressure on the cost of crude
oil, gasoline, diesel and airplane

To increase supplies, most companies are looking to tar sands in Canada or converting coal or natural gas into
liquid fuels, technologies that emit far more carbon dioxide than
conventional oil does.
EDITION 12.27 A BP - funded study out of the Harvard Kennedy School sees plenty of «

liquid condensate called DilBit.
The share of
liquids will probably remain constant but with a gradual transition from
conventional oil (Section 4.3.1.3) toward coal - to -
liquids, unconventional oils (Section 4.3.1.4) and modern biomass (Section 4.3.3.3).
