Crude oil is currently removed as "primary recovery", "secondary recovery", and tertiary recovery"
In Primary Recovery, all that is required is to sink a well into the reservoir and the pressure of the material above it will force the oil up the well pipe. This is the type of recovery associated with the "gusher well". Even if a well isn't a gusher, it can still be pumped up from the reservoir until the pressure drops too low.
In Secondary Recovery, the pressure in the well is increased by injecting something into the well such as steam, liquid water, natural gas, air or carbon dioxide. The injection occurs at the edge and/or bottom of the reservoir so as to cause the pressure to force the oil ahead of it towards the recovery well bore. Depending on what is injected, the injected material can also lower the viscosity of the oil and aid it in migrating towards the recovery well bore (which would actually be more a tertiary recovery method), but if the main purpose of injection is to boost the pressure, it is still considered secondary recovery.
In Tertiary Recovery, materials are injected into the well mainly to alter the physical properties of the oil, especially the surface tension, in order to get the oil to not stick as much to the matrix of the reservoir and to move more easily through it towards the recovery well. When steam is injected, the heat lowers the viscosity of the oil to make it flow more easily. Surfactant solutions can also be injected to lower the surface tension of the oil. and un-stick it from the reservoir matrix. Carbon dioxide flooding both thins out the oil (lower viscosity) and lowers the surface tension. A newer method is bio-flooding where specially designed microbes are injected with the water. The microbes attack the heavier molecules in the oil and break them down into smaller molecules, which makes the oil less viscous, and incidentally of greater value - gasoline, which is mostly lower weight hydrocarbons, sells for more than tar and asphalt, which are higher weight hydrocarbons.
pumped up with a flexible like and a rotating blade if they hit a gas like then that rig in the ocean will become a natural gas rig and if they hit oil then they will become the most famous type of rig an oil rig but sometimes if they hit the gas pockets it could destroy there rig

Oil often seeps to the surface, but when it is deep in the earth it is pumped out through an oil well.
Crude oil will adhere to almost any solid surface. It is easily removed at first, with soap and water. It can develop in time into a tarry substance, which is more difficult to remove.
It is a mixture of hydrocarbons, which can be separated by fractional distillation. Oil is NOT an element.
Crude Oil is a liquid.
Crude oil is inorganic.
No because crude oil does get to the surface so there are bugs that destroy it.
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.

Crude oil wasn't 'invented' ! It is a natural resource. There is a finite amount of crude oil in the Earth's surface - which will eventually run out... forcing us to use alternatives whether we want to - or not ! !

It is pumped out of oil reserves within the crust of the earth
Crude oil is a type of pure oil that is brought up to our surface by oil wells. Most of the places that we obtain oil is from the Middle East(Iraq, Iran, Saudi Arabia). You can probably buy containers of crude oil on craigslist or on eBay but I don't understand what you would use it for......
You probably mean the "specific gravity" of crude oil. The answer is yes. For example: crude oil with a specific gravity of less than 1.0 and is therefore lighter than water and will float on its surface. "Extra heavy crude oil" has a specific gravity greater than 1.0 and sinks to the bottom of water.

oil rigs- they drill in the ground (or in the ground under the sea) until hey reach a pocket of oil. they then connect the pocket to a pipeline and pump it to the surface
Crude oil is crude..
Polymers are not made into crude oil. Crude oil is made into polymers.
