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 ...
The abiogenic petroleum origin hypothesis proposes that most of earth's petroleum and natural gas deposits were formed inorganically, commonly known as abiotic oil. [1] Scientific evidence overwhelmingly supports a biogenic origin for most of the world's petroleum deposits. [2] [3] Mainstream theories about the formation of hydrocarbons on ...
In petroleum science, reservoir fluids are the fluids mixture contained within the petroleum reservoir which technically are placed in the reservoir rock. Reservoir fluids normally include liquid hydrocarbon (mainly Crude oil ), aqueous solutions with dissolved salt, hydrocarbon and non-hydrocarbon gases such as methane and hydrogen sulfide [1 ...
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 ...
Effluent is defined by the United States Environmental Protection Agency (EPA) as "wastewater–treated or untreated–that flows out of a treatment plant, sewer, or industrial outfall. Generally refers to wastes discharged into surface waters". [ 1] The Compact Oxford English Dictionary defines effluent as "liquid waste or sewage discharged ...
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 ...
Decoupage or découpage ( / ˌdeɪkuːˈpɑːʒ /; [ 1] French: [dekupaʒ]) is the art of decorating an object by gluing colored paper cutouts onto it in combination with special paint effects, gold leaf, and other decorative elements. Commonly, an object like a small box or an item of furniture is covered by cutouts from magazines or from ...
Computer simulation of the Earth's magnetic field in a period of normal polarity between reversals [ 2] Geophysics ( / ˌdʒiːoʊˈfɪzɪks /) is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis.
