Tight oil is short for tight reservoir oil, which generally refers to the oil in the reservoirs with low porosity and poor permeability (the porosity is commonly less than 10%, and the in situ matrix permeability is less than 0.1 mD).The reservoir rock types include shale, siltstone, sandstone, limestone, dolomite and even volcanic rocks.
The USGS Energy Resources Program has studied oil shale resources of the United States, with a significant effort on the Eocene Green River Formation of Colorado, Utah, and Wyoming. This formation contains the largest oil shale deposits in the world. Oil shale, despite the name, does not actually contain oil, but is a precursor of oil that is converted to crude oil when heated.
Oil shale is a sedimentary rock. As it reaches its oil window, oil shale releases a liquid known as shale oil. Oil shale is the rock from which shale oil is extracted. Shale oil is similar to petroleum, and can …

Policymakers' recognition of oil as imperative to national defense — namely, its use as fuel for a petroleum-powered Naval fleet — led to the creation of the Naval Petroleum and Oil Shale Reserve (the Reserves) in 1912. The Reserves were meant to insulate the United States from foreign dependency on oil during times of war. The U.S ...

The largest shale oil formation is the Monterey/Santos play in southern California, which is estimated to hold 15.4 billion barrels or 64 percent of the total shale oil ...
OIL SHALE. Shale is a fine-grained sedimentary rock composed of a mud rich in clay- and silt-sized sediment grains. Some shale can also contain significant amounts of organic matter—the fossil remains of protozoans, microscopic animals, or plants—called kerogen. When kerogen-bearing shale is buried deeply enough and for millions of years ...
Additionally, the country holds significant shale oil reserves, estimated at around 5.7 billion barrels. Geographical Distribution. The majority of Algeria's shale gas and oil reserves are located in the lower Silurian and Devonian formations. The most notable shale formation is the Ahnet Basin, situated in the central part of the country.
Reserves Oil shale deposits in Jordan. Jordan has significant oil shale deposits occurring in 26 known localities. According to the World Energy Council, Jordan has 8th largest oil shale resource in the world. Geological surveys indicate that the existing deposits underlie more than 60% of Jordan's territory.
Estimated shale oil and shale gas resources in the United States and in 137 shale formations in 41 other countries represent 10% of the world's crude oil and 32% of the world's natural gas technically …
The study aimed for in-situ shale oil extraction from a vast shale oil reserve in Jordan, with a focus on mitigating energy usage and environmental issues. The study suggested utilizing recovered heat from the production stream along with an external source, which may include natural gas, solar thermal energy, or a combination of both, to ...
Map of countries with proven oil reserves - according to U.S. EIA (start of 2017) Trends in proven oil reserves in top five countries, ... because the production is mostly from shale but the reserves cited omit all shale reserves.) Comparison of proven oil reserves from some widely used sources (billions of barrels, as of 31 Dec 2014) ...

Total 3,357 22,882 Increase in total resources due to inclusion of shale oil and shale gas 11% 47% Shale as a percent of total 10% 32% ...
Water will be a by-product of the process, rather than being consumed by it in large volumes. Vinegar says Israel has the third-biggest oil shale deposits in the world, outside the US and China ...
The oil saturation method refers to the reserve calculation method in conventional oil and gas exploration, and the formula is as follows: (3) Q o = 100 × A × h × φ × S o × ρ o / B oi where: Q o = reserves of shale oil, 10 4 t; A = oil-bearing area, km 3; h = effective thickness of shale, m; φ = effective porosity, %; S o = original oil ...
In 1912, the President, by Executive Order, established the Naval Petroleum and Oil Shale Reserves. This office has overseen the U.S. strategic interests in oil shale since that time. The huge resource base has stimulated several prior commercial attempts to produce oil from oil shale, but these attempts have failed primarily because of the ...
The shale oil-equivalent reserves in the world is 6902 × 10 8 tons, three times the world's crude oil reserves, as shown in Figure 1 (Zuckerman, 2014). In 2014, the shale oil production reached 2.1 × 10 8 tons, one-third of conventional petroleum production in the …

As unconventional reserves, oil shale deposits require additional oil recovery techniques to achieve favorable production levels. The efficiency of a shale reservoir development project is highly dependent on the application of enhanced oil recovery (EOR) techniques. There are many studies devoted to discrete investigations of each EOR method. Most of …
