Unconventional oil reserves by country

Leading countries based on conventional oil reserves in 2017 (in million metric tons) This statistic shows the leading countries worldwide based on conventional oil reserves in 2017. In that year, Venezuela had approximately 47.39 billion metric tons of conventional crude oil reserves, and thus has the largest reserves of conventional oil worldwide. On November 28 The United States Geological Survey (USGS) published an assessment of continuous (unconventional or ‘tight’) resources in a part of the prolific Permian oil and gas basin that straddles Western Texas and Southeastern New Mexico. The unconventional oil is divided into natural bitumen, extra heavy oil and shale oil. Three scenarios are presented: the production peak ranges between 49 mb/d in 2076 and 88 mb/d in 2084. The oil shale has the largest potential followed by natural bitumen and extra heavy oil.

Technically recoverable reserves of unconventional natural gas worldwide as of 2016, by country (in trillion cubic meters)Unconventional natural gas reserves worldwide by country 2016. Natural gas reserves to production ratio worldwide from 1980 to 2018 (in years)Global years of remaining natural gas supply 1980-2018. 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 . The most current version of each country chapter is linked in the table of countries below. This website highlights conventional and unconventional (continuous) oil and gas resources (such as shale gas) for more than 170 basins. Conventional Oil and Gas Assessments In 2012, the USGS completed a comprehensive assessment of priority basins throughout the world. According to the statistics of the USGS and DOE, the volume of global unconventional oil resources is 4495 × 10 8 t, including shale oil at 2770 × 10 8 t, bitumen at 2770 × 10 8 t, and heavy oil at 2770 × 10 8 t, which is equal to that of conventional petroleum resources. Using a geology-based assessment methodology, the U.S. Geological Survey estimated undiscovered, technically recoverable mean resources of 5.6 billion barrels of oil and 109.1 trillion cubic feet of gas in the Jurassic Hanifa-Tuwaiq Total Petroleum System of the Arabian Peninsula. Table 16 shows the estimated volumes of nonproducing proved reserves of crude oil, lease condensate, nonassociated natural gas, associated-dissolved natural gas, and total natural gas for 2018. As of December 31, 2018, the United States had 17.3 billion barrels of crude oil proved reserves and 192.1 Tcf of natural gas proved reserves in nonproducing reservoirs. Leading countries based on conventional oil reserves in 2017 (in million metric tons) This statistic shows the leading countries worldwide based on conventional oil reserves in 2017. In that year, Venezuela had approximately 47.39 billion metric tons of conventional crude oil reserves, and thus has the largest reserves of conventional oil worldwide.

Technically recoverable tight oil resources according to the EIA. Rank, Country/ Region, Shale Oil proven reserves billion barrels. Total, World, 425. 1, Bahrain 

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. Considering 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. With 300,878 million barrels of proven reserves, Venezuela has the largest amount of proven oil reserves in the world. The country's oil is a relatively new discovery. Previously, Saudi Arabia had always held the number one position. The oil sand deposits in Venezuela are similar to those in Canada. Proven Oil Reserves showcases the commercially available (and theoretically recoverable) oil reserves of a given country based on its recognized reservoirs. For the purposes of the GFP ranking, oil is a highly-valued component when considering a prolonged military campaign and is used in conjunction with oil consumption and oil production values. This is a list of countries by proven oil reserves. Proven reserves are those quantities of petroleum which, by analysis of geological and engineering data, can be estimated, with a high degree of confidence, to be commercially recoverable from a given date forward from known reservoirs and under current economic conditions. On November 28 The United States Geological Survey (USGS) published an assessment of continuous (unconventional or ‘tight’) resources in a part of the prolific Permian oil and gas basin that straddles Western Texas and Southeastern New Mexico.

According to the statistics of the USGS and DOE, the volume of global unconventional oil resources is 4495 × 10 8 t, including shale oil at 2770 × 10 8 t, bitumen at 2770 × 10 8 t, and heavy oil at 2770 × 10 8 t, which is equal to that of conventional petroleum resources.

OPEC holds 71.8% of global reserves. The top countries in terms of reserves are Venezuela (17.5% of global reserves), closely followed by Saudi Arabia (17.2%),
