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) have been completed. [8] [9] It is refined and separated, most easily by distillation , into a large number of consumer products, from gasoline (petrol) and kerosene to asphalt and chemical reagents used to make plastics and pharmaceuticals . [10] Petroleum is used in manufacturing a wide variety of materials, [11] and it is estimated that the world consumes about 95 million barrels each day.
