Either it comes gushing out because it is under pressure (many feet of heavy rock above) or they pump some liquid (water) down to push the oil out.
Oil is extracted from the ground through a process called drilling. A drill is used to create a well into the underground reservoir of oil. Once the well is drilled, the pressure from the reservoir forces the oil to the surface where it can be collected. Pump jacks are sometimes used to help bring the oil to the surface.
Crude oil is brought to Earth's surface through the process of drilling. Wells are drilled deep into the earth where crude oil deposits are located. Once the well reaches the oil reservoir, the pressure underground pushes the oil up to the surface, where it can be collected and processed.
In the early years the oil was not replaced by anything. This often caused land and seabottoms to sink, even several meters. These days one pump in seawater in order to get more oil and gas out of a drillhole/oilwell.
The equipment used to extract oil from the ground is called an oil rig or drilling rig. It is a complex structure designed to drill deep into the Earth's surface to reach oil reservoirs.
It is called oil drilling or petroleum extraction.
Crude Oil
Gusher
Oil rigs drill into the ground to find oil. They then pump the oil out of the ground to ready it for delivery to places that will refine it. They can be on land or in the ocean.

i am form filsham valley oil is pumped out by using a large pump
It has to be pumped. A drill is used to drill down to the oil and then a pump is setup to get the oil out.
Second Answer;;People began to pump oil from the ground because, chemists invented a way to convert unprocessed oil, or crude oil into a fuel called kerosene. Kerosene could be used for cooking, heating and lighting. Then there was a sudden demand for oil. It further expanded when Edwin L. Drake proved that it was possible to pump crude oil from the ground. Suddenly wildcatters or oil prospectors drilled for oil in Ohio, Pennsylvania, and West Virginia. In order to obtain raw materials for industry: fuel, lubricants, etc.
have the sending unit checked.and also check the circuit.it may be shorted to ground.
Well, yes...but crude oil isn't exactly made; they drill a hole in the ground and pump it out.
th purpose of an oil pump is to PUMP...OIL

You pipe it up from under the ground and pump it into tankers, usually, or sometimes pipelines, to take it to the refinery.
