The term “oil shale” is a misnomer. It does not contain oil nor is it commonly shale. The organic material is chiefly kerogen, and the “shale” is usually a relatively hard rock, called marl. Properly processed, kerogen can be converted into a substance somewhat similar to petroleum. For crude oil occurring in shale reservoirs and also referred to as 'shale oil', see Tight oil. Shale oil is an unconventional oil produced from oil shale rock fragments by pyrolysis, hydrogenation, or thermal dissolution. These processes convert the organic matter within the rock ( kerogen) into synthetic oil and gas. 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. Total U.S. oil reserves in 2017 exceeded a brief, one-year, 47-year-old record, highlighting the importance of crude oil development in shales and low permeability plays, mainly in the Southwest. The new record for natural gas extends a longer-term trend of development, mainly in shale plays in the Northeast. The oil reserves of the United States (US) soared to new heights in recent years due to increased usage of unconventional drilling methods that enable extraction of more shale oil and gas than was previously possible. As a result of these, especially fracking and horizontal drilling, US reserves surpassed 36,000 million barrels in 2012 for the first time since 1975.
29 Jan 2019 For the shale gas reserves, the same study reclassifies Algeria to the third position after the United States and China, with an estimated reserve of
12 Nov 2019 Countries with the largest amount of technically recoverable shale oil resources include Russia, the United States, China, Argentina, and Libya. 2 Jan 2014 More than half of the identified shale oil resources outside the United States are concentrated in four countries—Russia, China, Argentina, and 13 Jan 2019 Read the article for yourself, but it cited the Federal Reserve Bank of Dallas Thriving so fast, our production growth for shale oil and gas has 21 Dec 2018 Located in the Wolfcamp Shale and overlying Bone Spring Formation, the unproven, technically recoverable reserves are officially the largest on 21 Aug 2019 Fracking: UK shale gas reserves 'significantly lower than previous estimates'. The new research suggests only under 10 years worth of gas 26 Nov 2019 Past estimates of India's shale reserves vary widely from ONGC's 187 trillion cubic feet (TCF) of shale gas in 5 basins to US Energy Information

The USGS estimates that over 46 billion barrels of oil, 280 trillion cubic feet of gas, and 20 billion barrels of natural gas liquids are trapped in these low-permeability shale formations.
15 Jun 2016 Ultra Petroleum Corp. was a shale success story. A former penny stock that made the big leagues, it was worth almost $15 billion at its 2012

Commercial grades of oil shale, as determined by their yield of shale oil, ranges from about 100 to 200 liters per metric ton (l/t) of rock. The U.S. Geological Survey has used a lower limit of about 40 l/t for classification of Federal oil-shale lands. Others have suggested a limit as low as 25 l/t.
15 Feb 2018 Gas is actually a vital part of the shale oil extraction process: if only oil is present in the underground deposits, extraction is difficult. The ideal 14 Jan 2015 It involves horizontal drilling and the hydraulic fracturing (or fracking) of underground rock formations containing deposits of crude oil that are 6 Mar 2018 gas reserves can be linked to specific developments associated with the Shale gas revolution since 2009. Furthermore, returns are positively 26 Sep 2017 The Duvernay lags western Canada's Montney and Liard Basin shale deposits in terms of marketable natural gas reserves, which hold 449 Tcf Shale gas & oil is defined as natural gas & oil from shale formations. the country holds promising reserves of Shale Gas & Oil resources and the following
Commercial grades of oil shale, as determined by their yield of shale oil, ranges from about 100 to 200 liters per metric ton (l/t) of rock. The U.S. Geological Survey has used a lower limit of about 40 l/t for classification of Federal oil-shale lands. Others have suggested a limit as low as 25 l/t. The oil shale interval in the Piceance Basin is subdivided into seventeen “rich” and “lean” zones and each interval was assessed for variations in gallons per ton, barrels per acre, and total barrels in each 36-square mile township. These zones are roughly time-stratigraphic units consisting of distinctive, Shale oil is a high-quality crude oil that lies between layers of shale rock, impermeable mudstone, or siltstone. Oil companies produce shale oil by fracturing the layers of rock that contain the layers of oil. Don't confuse shale oil with oil shale. That is rock suffused with kerogen, a precursor to oil.
