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 earth ...
Nikolai Kudryavtsev. Nikolai Alexandrovich Kudryavtsev (Russian: Николай Александрович Кудрявцев; Opochka, October 21, 1893 – Leningrad, December 12, 1971) was a Soviet Russian petroleum geologist. He is the founding father of modern abiogenic theory for origin of petroleum, which states that some petroleum is ...
The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could change Earth's energy ...
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 ...
An oil refinery in Ahmadi Governorate in Kuwait. Petroleum or crude oil, also referred to as simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrogencarbons, [1] and is found in geological formations. The name petroleum covers both naturally occurring unprocessed crude oil and petroleum products that consist of ...
The hydrophobic effect is the observed tendency of nonpolar substances to aggregate in an aqueous solution and to be excluded by water. [1][2] The word hydrophobic literally means "water-fearing", and it describes the segregation of water and nonpolar substances, which maximizes the entropy of water and minimizes the area of contact between ...
The Hubbert peak theory says that for any given geographical area, from an individual oil-producing region to the planet as a whole, the rate of petroleum production tends to follow a bell-shaped curve. It is one of the primary theories on peak oil. Choosing a particular curve determines a point of maximum production based on discovery rates ...
The oil drop experiment was performed by Robert A. Millikan and Harvey Fletcher in 1909 to measure the elementary electric charge (the charge of the electron). [1][2] The experiment took place in the Ryerson Physical Laboratory at the University of Chicago. [3][4][5] Millikan received the Nobel Prize in Physics in 1923. [6]
