Proved reserves of crude oil in the United States increased 12%, from 39.2 billion barrels at year-end 2017 to 43.8 billion barrels at year-end 2018, setting another U.S. record for crude oil proved reserves (Table 7). According to a new analysis from oil and gas consulting firm Rystad Energy, the United States is the country with the largest volume of oil reserves, with Russia and Saudi Arabia coming in second and third, respectively. Rystad’s analysis includes oil in proven, existing fields, Unconventional oil refers to oil reserves that cannot be feasibly accessed using conventional drilling techniques. These reserves - notably tight oil, oil shale, and bitumen - must be extracted using novel methods. In contrast, conventional oil typically refers to crude oil which uses conventional vertical drilling How much shale (tight) oil is produced in the United States? The U.S. Energy Information Administration (EIA) estimates that in 2019, about 2.81 billion barrels (or 7.7 million barrels per day) of crude oil were produced directly from tight oil resources in the United States. This was equal to about 63% of total U.S. crude oil production in 2019. 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 .
origins of these shale deposits vary greatly. The United States has the largest known resource of oil shale in the world - an estimated 6 trillion barrels (1).
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 Unconventional oil. Within the vast unconventional resources category, there are several different types of hydrocarbons, including very heavy oils, oil sands, oil shales, and tight oils. By the early 21st century, technological advances had created opportunities to convert what were once undeveloped resource plays into economic reserves. Conventional and Unconventional Oil and Gas in The U.S. The main reason for developing advanced technologies to explore and extract hydrocarbons in the U.S. is the disparity between conventional and unconventional oil and gas reservoirs. This also applies to conventional and unconventional natural gas. Proved reserves of crude oil in the United States increased 12%, from 39.2 billion barrels at year-end 2017 to 43.8 billion barrels at year-end 2018, setting another U.S. record for crude oil proved reserves (Table 7).

Total global oil reserves are estimated at 2,092 billion barrels, or 70 times the current production rate of about 30 billion barrels of oil a year. For comparison, cumulatively produced oil through 2015 amounted to 1,300 billion barrels. Unconventional oil recovery accounts for 30 percent of the global recoverable oil reserves, while offshore fields account for 33 percent of the total. The seven major oil companies hold less than 10 percent of the total recoverable reserve base.

Oil Shale, Work and Environmentalism | ResearchGate, the professional network for scientists. Figure 2 – U.S. oil shale resource vs. foreign oil reserve. Five NGS' reported that hydro fracturing in shale gas and oil deposits is prohibited; the United States Geological Survey (USGS) (Gautier et al. 2013). While oil demand is up everywhere, the U.S. remains the king of consumers, slurping up Try to exploit the American West's vast deposits of oil shale and other Oil shale deposits exist in 33 countries.4 The U.S. has the largest oil shale resource in the world, approximately 6 trillion bbls of oil in place, with the Green River

Oil shale reserves refers to oil shale resources that are economically recoverable under current cubic metres) of shale oil, with the largest resource deposits in the United States accounting for more than 80% of the world total resource. The United States has the largest known deposits of oil shale in the world, according to the Bureau of Land Management and holds an 13 Dec 2019 Natural gas proved reserves from shale increased from 66% of total U.S. gas proved reserves in 2017 to 68% at year-end 2018 (Figure 12). The Bakken Field in North Dakota and Montana is the largest producing shale oil reserve.3 The field has layers of dense, oil-bearing rock about two miles 3 Dec 2019 Crude oil production and proved reserves from selected U.S. shale plays Proved reserves of the top seven U.S. oil reserves states, 2014–18 . Thanks to unconventional resources, the United States is ahead of both Russia and Saudi Arabia in Rystad Energy's latest estimate of global oil reserves.
