Condensation Mechanism of Hydrocarbon Field Formation

Millions of years ago, algae and plants lived in shallow seas. After dying and sinking to the seafloor, the organic material mixed with other sediments and was buried. Over millions of years under high pressure and high temperature, the remains of these organisms transformed into what we know today as fossil fuels. Today, petroleum is found in vast underground reservoirs where ancient seas were located. Petroleum reservoirs can be found beneath land or the ocean floor. Crude oil is usually black or dark brown, but can also be yellowish, reddish, tan, or even greenish.

A short introduction into the occurrence and bulk composition of thermogenic hydrocarbons as a fraction of natural petroleum in sedimentary basins is given. The main driving forces for the generation of thermogenic petroleum besides temperature, namely, time, pressure, and catalysts, are discussed as well as basic reaction mechanisms. The main part describes classical and novel analytical methods used to assess timing, amount, and composition of generated petroleum as a function of organic matter type and maturity. Recent work is presented and research needs are identified. Skip to main content.

Although it is recognized that the original source of carbon and hydrogen was in the materials that made up primordial Earth , it is generally accepted that these two elements had to pass through an organic phase to be combined into the varied complex molecules recognized as hydrocarbons. The organic material that is the source of most hydrocarbons has probably been derived from single-celled planktonic free-floating plants, such as diatoms and blue-green algae , and single-celled planktonic animals, such as foraminifera , which live in aquatic environments of marine, brackish, or fresh water. Such simple organisms are known to have been abundant long before the Paleozoic Era , which began some million years ago. Rapid burial of the remains of the single-celled planktonic plants and animals within fine-grained sediments effectively preserved them. This provided the organic materials, the so-called protopetroleum, for later diagenesis a series of processes involving biological, chemical, and physical changes into true petroleum.

In organic chemistry , a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons from which one hydrogen atom has been removed are functional groups called hydrocarbyls. Because of their diverse molecular structures, it is difficult to generalize further. Most anthropogenic emissions of hydrocarbons are from the burning of fossil fuels including fuel production and combustion.

From planktonic remains to kerogen: the immature stage

Сьюзан открыла рот, желая сказать, что она все понимает, но ее слова были заглушены внезапным пронзительным звуком. Тишина шифровалки взорвалась сигналом тревоги, доносившимся из служебного помещения ТРАНСТЕКСТА. Сьюзан и Стратмор в недоумении посмотрели друг на друга. - Что это? - вскрикнула Сьюзан между сигналами. - ТРАНСТЕКСТ перегрелся! - сказал Стратмор. В его голосе слышалось беспокойство.  - Быть может, Хейл был прав, говоря, что система резервного питания подает недостаточное количество фреона.

Я проделал анализ и получил именно такой результат - цепную мутацию. Теперь Сьюзан поняла, почему сотрудник систем безопасности так взволнован. Цепная мутация. Она знала, что цепная мутация представляет собой последовательность программирования, которая сложнейшим образом искажает данные. Это обычное явление для компьютерных вирусов, особенно таких, которые поражают крупные блоки информации.

 - Стратмор пожал плечами.  - Фонд электронных границ замучил неприкосновенностью частной жизни и переписки. Сьюзан хмыкнула. Этот фонд, всемирная коалиция пользователей компьютеров, развернул мощное движение в защиту гражданских свобод, прежде всего свободы слова в Интернете, разъясняя людям реальности и опасности жизни в электронном мире.

У него был такой вид, словно он только что увидел привидение. - Какого черта здесь нужно Чатрукьяну? - недовольно поинтересовался Стратмор.  - Сегодня не его дежурство.
