Unconventional oil is petroleum produced or extracted using techniques other than the conventional method. Oil industries and governments across the globe are investing in unconventional oil sources due to the increasing scarcity of conventional oil reserves. Unconventional oil and gas have already made a dent in international energy linkages by reducing US energy import dependency. These formations are now considered as unconventional gas and oil reservoirs. The exploitation of these resources applies unconventional innovative techniques. This has added large reserves mostly in North American oil provinces. In many other parts of the world, unconventional gas and oil resources have been discovered but have not yet been The first edition was released in 2011 and updates are released on an on-going basis. Four countries were added in 2014: Chad, Kazakhstan, Oman and the United Arab Emirates (UAE) and are available as supplemental chapters to the 2013 report Technically Recoverable Shale Oil and Shale Gas Resources . OSLO, NORWAY–The United States now holds the world’s largest recoverable oil reserve base–more than Saudi Arabia or Russia–thanks to the development of unconventional resource plays. Ranking nations by the most likely estimate for existing fields, discoveries and as-of-yet undiscovered fields (proved, probable. The United States Geological Survey just identified the world's largest unconventional oil and gas potential buried within the Permian basin, containing over 46 billion barrels of oil and 280

Based on data from OPEC at the beginning of 2013 the highest proved oil reserves including non-conventional oil deposits are in Venezuela (20% of global reserves), Saudi Arabia (18% of global reserves), Canada (13% of global reserves), and Iran (9%).

By contrast, worldwide unconventional natural gas natural gas reserves ( including unconventional gas  17 Dec 2013 Energy Price, Technology and the Evolution of Oil & Gas Reserves. 4 Tight Oil, Shale Gas & the Long-Term Global Energy Outlook. 62.
