The Origin of the Petroleum System: Most scientific evidence shows that petroleum originates from the decay of organic matter buried in sediments. In petroleum geology, source rock refers to rocks from which hydrocarbons have been generated or are capable of being generated. Four elements listed in this video, but a more comprehensive list is shown in the reading "Read: Conventional Oil and Gas".

All fossil fuels, including coal, are considered an indirect form of ____________ energy. dinosaur tissue preserves in terrestrial environments. The Origin of oil and gas - Organic matter Petroleum was formed from organic matter. Practically all shales and carbonate rocks contain indigenous organic matter disseminated in three forms: (1) soluble hydrocarbons, which are similar in composition to the heavier fractions of crude oil found in reservoir rock, (2) soluble asphalt, which is similar to the asphaltic constituents of crude oil, and (3) insoluble organic matter (kerogen), which is pyrobituminous in nature. Source rock is where the petroleum matures as for the reservoir rock is where the petroleum pools. Methane clathrates are stable in __________ conditions.

Oil is used today as the basis for a long list of products. A tiny proportion of this organic matter — about 0.1% — escapes this fate. The high molecular weight sedimentary organic matter is termed kerogen from the Greek for “wax former.” It is worth noting that not all of life’s organic matter is reflected in kerogen. 2/ Reservoir rock: a porous and permeable rock through which HCs can flow, and in which they can accumulate.

Why must oil shale be heated to extract hydrocarbons? These organic contents, depending on their nature, depositional environment, temperature, pressure, and depth of burial are capable of generating petroleum. 1/Source rock: an organic rich rock capable of generating HCs. Transported by water, it sometimes sinks to the bottom of the sea or large continental lakes. It is partly preserved in these poorly oxygenated environments, well away from tidal currents. The result is Choose one: A. coal. 4/ Overburden rock: is required to bury the source rock to depths where HCs are generated. Petroleum is a Latin word of (Petra ‘‘rock’’ + Oleum ‘’ oil ‘’), It is completely different than oil that comes from vegetable sources such as the olive, but modern research has traced its origin to the lipids (oils) of planktonic (free floating) plants and animals which live in brackish water such as blue-green algaes and foraminifera.
