How are oil and gas trapped in the ground?
When they met a layer of cap rock (a rock with no spaces between the grains) the oil and gas are trapped. A well is drilled so that the crude oil and other liquids travel up the bore hole. When it comes to the surface the crude oil has to be moved closer to where it is needed.
What happens when oil is pumped out of the Earth?
But typically the oil isn’t sitting in a subterranean lake but rather in sand, shale, or porous rock. Once the oil is removed, the weight of the earth above flattens out what’s left and the land sinks — this is called subsidence. The same thing can happen with groundwater pumpage, as we discussed a while back.
How are oil companies pumping out the oil?
Following initial extraction of crude, oil companies may flood the reservoir with water to flush out additional petroleum; this process has largely halted subsidence in places like Long Beach. Now experts are trying the same trick using carbon dioxide, both to increase oil production and to sequester greenhouse gases.
Where did William Drake drill the first oil well?
He struck oil after drilling 69 ft. into the ground in Titusville, Pa., launching the petroleum age and making Titusville ground zero for the Pennsylvania oil rush. Unlike Ahab (spoiler alert), Drake wasn’t destroyed by his discovery — at least not instantly.

How did the American oil industry get its start?
How the American Oil Industry Got Its Start This is the well near Titusville, Penn., that pumped the petroleum industry into existence 100 years ago. The picture was taken four years after Col. Edwin L. Drake struck oil on Aug. 27, 1859.
Why was oil discovered and what did they do with it?
This lotion is the future wealth of this country, it’s the welfare and prosperity for its inhabitants, it’s a new source of income for the poor people and a new branch of industry, which shall bear plentiful fruits
What did people use oil for before the Industrial Revolution?
Settlers used oil as an illuminant for medicine, and as grease for wagons and tools. Rock oil distilled from shale became available as kerosene even before the Industrial Revolution began.
