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.

Petroleum Formation and Occurrence - By B. P Tissot, D. H. Welte

Dumble, E. Edward Orton, in his Report on the Occurrence of Petroleum, NaturalGas and Asphalt Rock in Western Kentucky, thus clearly states his ideas of theuniversal dissemination and rare accumulations of the bitumens:. The valuable accumulations of thesesubstances are rare, it is true, but one can scarcely go amiss of petroleum, asphalt or gas, at least in small quantities, among the stratified rocks that retain their original structure. Geological Survey, , discussing these views of Orton with similar views ofT.

It is commonly refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation , i. It consists of naturally occurring hydrocarbons of various molecular weights and may contain miscellaneous organic compounds. A fossil fuel , petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae , are buried underneath sedimentary rock and subjected to both intense heat and pressure.

AAPG Bulletin ;; 97 3 : — The basin has a complex history, having evolved from a rift basin to an arc basin and finally having become a retroarc foreland basin. The basin has oil and gas seeps.

 Три, - прошептала она, словно оглушенная. - Три! - раздался крик Дэвида из Испании. Но в общем хаосе их никто, похоже, не слышал.

 Рекомендации? - выпалил Джабба.  - Вы ждете рекомендаций. Что ж, пожалуйста.

Лучшее, что мог сделать директор, - не мешать ему работать и наблюдать за тем, как коммандер творит свое чудо. Стратмор разработал план… и план этот Фонтейн не имел ни малейшего намерения срывать. ГЛАВА 75 Пальцы Стратмора время от времени касались беретты, лежавшей у него на коленях. При мысли о том, что Хейл позволил себе прикоснуться к Сьюзан, кровь закипела в его жилах, но он помнил, что должен сохранять ясную голову, Стратмор с горечью признал, что сам отчасти виноват в случившемся: ведь именно он направил Сьюзан в Третий узел. Однако он умел анализировать свои эмоции и не собирался позволить им отразиться на решении проблемы Цифровой крепости.

Origin of hydrocarbons

 Червь удвоил скорость! - крикнула Соши.  - Штрафная санкция. На центральном экране прямо под извещением об ошибке ВР представила зрителям ужасающую картину.
