Question

{(3) How is petroleum and mineral oil formed?​

Answer 1

Answer:

A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both intense heat and pressure. Petroleum has mostly been recovered by oil drilling (natural petroleum springs are rare).

Answer 2

Petroleum has mostly been recovered by oil drilling (natural petroleum springs are rare). Drilling is carried out after studies of structural geology (at the reservoir scale), sedimentary basin analysis, and reservoir characterisation (mainly in terms of the porosity and permeability of geologic reservoir structures).[2][3] Recent improvements to technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into numerous products for direct use or use in manufacturing, such as gasoline (petrol), diesel and kerosene to asphalt and chemical reagents (ethylene, propylene, butene,[4] acrylic acid,[5][6][7] para-xylene[8]) used to make plastics, pesticides and pharmaceuticals.[9] Petroleum is used in manufacturing a wide variety of materials,[10] and it is estimated that the world consumes about 100 million barrels each day.
