  2. History of fluid mechanics - Wikipedia

    en.wikipedia.org/wiki/History_of_fluid_mechanics

    The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history. The field has undergone a continuous evolution, driven by human dependence on water, meteorological conditions and internal ...

  3. Drilling fluid - Wikipedia

    en.wikipedia.org/wiki/Drilling_fluid

    In geotechnical engineering, drilling fluid, also known as drilling mud, is used to aid the drilling of boreholes into the earth. Used while drilling oil and natural gas wells and on exploration drilling rigs, drilling fluids are also used for much simpler boreholes, such as water wells. The two main categories of drilling fluids are water ...

  4. Naphtha - Wikipedia

    en.wikipedia.org/wiki/Naphtha

    Naphtha. Naphtha ( / ˈnæpθə / or / ˈnæfθə /) is a flammable liquid hydrocarbon mixture. Generally, it is a fraction of crude oil, but it can also be produced from natural-gas condensates, petroleum distillates, and the fractional distillation of coal tar and peat. In some industries and regions, the name naphtha refers to crude oil or ...

  5. Origin of water on Earth - Wikipedia

    en.wikipedia.org/wiki/Origin_of_water_on_Earth

    The origin of water on Earth is the subject of a body of research in the fields of planetary science, astronomy, and astrobiology. Earth is unique among the rocky planets in the Solar System in having oceans of liquid water on its surface. [ 2] Liquid water, which is necessary for all known forms of life, continues to exist on the surface of ...

  6. History of the petroleum industry - Wikipedia

    Oil field in California, 1938. The modern history of petroleum began in the 19th century with the refining of paraffin from crude oil. The Scottish chemist James Young in 1847 noticed a natural petroleum seepage in the Riddings colliery at Alfreton, Derbyshire from which he distilled a light thin oil suitable for use as lamp oil, at the same time obtaining a thicker oil suitable for ...

  7. Hygroscopy - Wikipedia

    en.wikipedia.org/wiki/Hygroscopy

    Hygroscopy is "exhibited in the most comprehensive sense, as displayed. in the condensation of the water-vapour of the air on the cold surface of a glass; in the capillarity of hair, wool, cotton, wood shavings, etc.; in the imbibition of water from the air by gelatine; in the deliquescence of common salt; in the absorption of water from the ...

  8. Dissolved air flotation - Wikipedia

    en.wikipedia.org/wiki/Dissolved_air_flotation

    Dissolved air flotation. Dissolved air flotation ( DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.

  9. Petroleum geology - Wikipedia

    en.wikipedia.org/wiki/Petroleum_geology

    Petroleum geology is principally concerned with the evaluation of seven key elements in sedimentary basins : A structural trap, where a fault has juxtaposed a porous and permeable reservoir against an impermeable seal. Oil (shown in red) accumulates against the seal, to the depth of the base of the seal. Any further oil migrating in from the ...
