What rock has crude oil inside?
Oil shale.
Why crude oil prices falling?
Crude oil prices are falling because of oil shale drilling in the United States.
How is crude oil excavated?
Crude oil is excavated using an excavation machine. Crude oil easily comes to the surface and is easy to excavate, while shale oil is not.
What are pros and cons of oil shale energy?
Pros: ? Cons: more expensive than pumping crude oil
Are you making the best use of crude oil?
no
What is difference between barnett shale gas and propane and crude oil?
The "Barnett Shale" is a particular shale formation found in central North Texas, and Southern Ok, that can produce natural gas. The natural gas is the same gas found in any other formation only extracted a little differently. Propane would be refined from natural gas, with no regard as to where it came from. Crude oil, meaning oil extracted directly from the ground in it's natural state, is unrefined and can be full of impurities, water, etc., thus crude.
Why is oil shale better than crude oil?
Perhaps your question should be rephrased as: Is oil shale better than crude oil. My simple answer is: Not necessarily. The oil shale is correctly termed kerogen or "unmatured oil" that has been trapped in shales. Extracting and burning oil shales (rock + kerogen) is a low grade fuel (see related link) so I would not consider this better than a good grade crude (Sweet Texas crude). The transformation of the kerogen to a synthetic oil, which frequently is not better than common grades of sweet crude. For example, if there is high sulfur content, then market price may be lower than Texas sweet crude. Also, a complicating factor for refineries is the arsenic content, which comes from the retorting process, and would reduce the market price of the synethetic oil. As discussed in the related link, some of the lower gravity synthetic oil may be used to produce jet fuel or kerosene. The general rule that no two oil reservoirs produce the same crude, applies to synthetic oil from oil shale, but it is more complex as it depends on the kerogen present in the formaion and manner in which the kerogen is transformed into synthetic oil. Please read the related link.
Is gasoline and oil the same?
no my friend,they are not. CRUDE OIL- it is a mixture of a variety of compounds containing impurities that was formed from dead organic matter in the ocean over thousands of years of immense pressure and heat below the sea bed.it cannot be used effectively in it's raw form.therefore it undergoes fractional distillation to give a variety of products and substrates such as petrol,diesel,naphta.etc OIL- an oil is generally considered to be a mixture of fat and glyserol.some oils are prepared in other ways while those used in vehicles are extracted fom crude oil and mixed with som other chemicals. however,oil and crude oil are not the same.
What is unrefined petroleum called?
There are two possibilities here: crude oil or natural gas. It's possible that oil shale and tar sands could be thought of as unrefined petroleum sources as well.
What is the difference between Brent and WTI crude oils?
West Texas Intermediate (WTI) crude oil is of very high quality and is at refining a larger portion of gasoline. Its API gravity is 39.6 degrees, which makes it a "light" crude oil, and it contains only about 0.24 percent of sulfur (making a "sweet" crude oil). Brent Blend is actually a combination of crude oil from fifteen different oil fields located in the North Sea. It is still a "light" crude oil, but not quite as "light" as WTI, and it contains about 0.37 percent of sulfur (making it a "sweet" crude oil, but again slightly less "sweet" than WTI). Brent blend is good for making gasoline and middle distillates. WTI is more expensive than Brent.
Is shale oil another type of petroleum?
Shale oil is an oil distilled from shales and used as fuel
Why are we not producing oil from oil shale?
The reason that oil shale is not used to produce oil is because this is what keeps the oil well from collapsing after the oil is removed. If the oil shale were mined, the oil well would collapse into a large trench in the ground.
