Kerogen in crude oil
Using this method, the oils classified mainly as oil derived from type 1 kerogen contrary to type II/III already reported for Niger delta oil. The Vitrinite Reflectance Thus, it is used for organic matter that converts to petroleum (crude oil and natural gases) after burial and heating in sedimentary basins. Kero- gen is distinguished 150–200 °C, both depending on how quickly the source rock is heated) some types of kerogen release crude oil or natural gas, collectively known as Oil shale refers to crude oil trapped in sedimentary rock. The petroleum component is referred to as kerogen and it is solid unless heated. The portion of kerogen that is soluble is known as “bitumen;” bitumen typically being the heaviest component of crude oil. In fact, in a geologic sense, kerogen is 1 Aug 2017 Although kerogen plays a central role in hydrocarbon (i.e., crude oil and natural gas) production from source rocks in geologic environments,
These sediments are organic-rich, and have the potential to become a source for petroleum. Requirement #2 The formation of kerogen. burial of the organic-rich
Generally, the oil is less fluid than crude oil, becoming pourable at temperatures between 24 and 27 °C (75 and 81 °F), while conventional crude oil is pourable at temperatures between −60 to 30 °C (−76 to 86 °F); this property affects shale oil's ability to be transported in existing pipelines. As kerogen is a mixture of organic material, rather than a specific chemical; it cannot be given a chemical formula. Indeed its chemical composition can vary distinctively from sample to sample. Kerogen from the Green River Formation oil shale deposit of western North America contains elements in the proportions carbon 215 : hydrogen 330 : oxygen 12 : nitrogen 5 : sulfur 1. Oil shale crude is actually composed of kerogen. It is a waxy organic substance that was formed from algae, plants, vegetation, and all forms of animal life. It is a waxy organic substance that was formed from algae, plants, vegetation, and all forms of animal life. For this reason, oil shale not to be confused with shale oil is often called kerogen . Chemically, oil shale consists of carbon, hydrogen, oxygen, nitrogen, and sulphur and forms from compacted organic material. This rock has not been geologically buried for a time sufficient to produce conventional hydrocarbons.
1 Aug 2016 Time and temperature convert kerogen into petroleum. The hydrogen content of kerogen is the controlling factor for oil vs. gas yields from the
For this reason, oil shale not to be confused with shale oil is often called kerogen . Chemically, oil shale consists of carbon, hydrogen, oxygen, nitrogen, and sulphur and forms from compacted organic material. This rock has not been geologically buried for a time sufficient to produce conventional hydrocarbons. According to Live Science, the temperatures are in the 120 to 300 degree-Fahrenheit range (48-148 degree-Celcius) when crude oil is forming.DNA in "dry" conditions completely degrades at temperatures above 190 degree-Celcius. Which means that there could be DNA in the oil itself if there are some surviving cells, however, outside the cells there are DNases which will chew up DNA.
Oil shale refers to crude oil trapped in sedimentary rock. The petroleum component is referred to as kerogen and it is solid unless heated.
Oil shale is essentially rock that contains solid bits of kerogen, a precursor to oil. All oil is from organic matter that is subjected to intense heat and pressure until it breaks down into hydrocarbons. With the kerogen in oil shale, there wasn’t quite enough heat to finish the job – but that, of course, can be fixed. Generally, the oil is less fluid than crude oil, becoming pourable at temperatures between 24 and 27 °C (75 and 81 °F), while conventional crude oil is pourable at temperatures between −60 to 30 °C (−76 to 86 °F); this property affects shale oil's ability to be transported in existing pipelines.

14 Jun 2010 A source rock is a fine grained sediment rich in organic matter that could generate crude oil or natural gas after thermal alteration of kerogen in
29 May 2007 Oil shale crude is actually composed of kerogen. It is a waxy organic substance that was formed from algae, plants, vegetation, and all forms of crude oil. The intricacies of the maturation process are, however, not well understood.
