Crude (天然的 未加工的) oil is petroleum that comes directly from deep in the ground. It is then taken to a refinery. a refinery is a kind of factory to refine oil. At a refinery the crude oil is separated into many parts. From the refined petroleum we get important things such as ...
So, instead of being produced from the remains of plankton, dinosaur remains, and ancient conifers and ferns, petroleum and other hydrocarbons might just be formed deep below the ocean floor, in the presence of water and ultramafic rocks. Our earth may just be producing more oil, right ...
Shale gas or unconventional natural gas is found in tiny pores within rocks Associated natural gas is found in crude oil deposits When natural gas is withdrawn from its origin, it contains natural gas liquids (NGLs) like ethane, propane, butanes, pentanes, and water vapor. This wet natural ...
citrusy sweetness. Triple sec is made by distilling neutral spirits with the dried peels of bitter and sweet oranges. The infusion process extracts the essential oils and flavors from the orange peels, which are then blended with sugar to balance the bitterness. Its defining characteristics include...
As rocks break down, the resulting materials are transported by wind, water or ice (glaciers) and end up as sediment in the sea or -- as we'll learn in this article -- as sand dunes. For example, desert sand is likely the result of a dried-up glacier or ancient sea or lake. ...
Fossil fuel is a common word used to refer to buried flammable geologic deposits of organic substances. They are created by decomposed plants and animals which were altered to natural gas, heavy oils or crude oil due to being exposed to a lot of heat and
Oil and gas are less dense than water, so they migrate through porous sedimentary rock toward the earth's surface. When the hydrocarbons are trapped beneath less-porous cap rock, an oil and gas reservoir is formed. These reservoirs of oil and gas represent our sources ofcrude oiland natural...

Oils generated from organic matter of the source rocks contain biomarkers that are specific for depositional environments. Therefore, the oil biomarkers can be used to prove the existence of paleogeographic sites / depositional environments formed by tectonics. This means that oil biomarkers, indirectly,...
