Source rocks are one of the necessary elements of a working petroleum system. They are organic-rich sediments that may have been deposited in a variety of environments including deep water marine, lacustrine and deltaic.

2022年2月4日 · A source rock is a rock that is capable of generating or that has generated movable quantities of hydrocarbons. The first factor to be assessed in an exploration play in an area yet to be drilled is whether a source rock is present.

Source rocks are rocks that contain sufficient organic material to create hydrocarbons when subjected to heat and pressure over time. Source rocks are usually shales or limestones (sedimentary rocks).

2014年12月1日 · Understanding source rock provides a key to evaluating the hydrocarbon potential of super basins and an important tool for basin exploration. Geologists get the basics right, in general, but sometimes they might be thinking about source rock the wrong way.

2018年2月7日 · This chapter overviews the petroleum source rocks characterization and hydrocarbon generation, based on organic geochemical characteristics (e.g., total organic carbon content (TOC), rock-eval pyrolysis and bitumen extraction); in addition, burial and thermal histories and timing of petroleum generation/expulsion for petroleum source rock ...

2021年9月15日 · Source Rock is the rock where petroleum formed. Source rocks are sedimentary rocks and typically shales (90%). The source rock was form along with deposition of the organic matter; thus, organic matter was abundant at the early age of a source rock.

Many of the source rocks for significant gas deposits appear to be associated with the worldwide occurrence of coal dated to Carboniferous and Early Permian times (roughly 358.9 million to 273 million years ago).

Source rocks are one of the necessary elements of a working petroleum system. They are organic-rich sediments that may have been deposited in a variety of environments including deep water marine, lacustrine and deltaic.

2022年4月13日 · Petroleum source rocks must contain sufficient quantities of sedimentary organic matter with a requisite ratio of hydrogen to carbon. In thermally immature rocks, sedimentary organic matter is dominated by kerogen (organic matter insoluble in common organic solvents) with small amounts of bitumen.

2016年1月1日 · A good source rock should have a total organic carbon (TOC) content of larger than 1 %. Most prominent source rocks are sapropels and black shales but also TOC-rich carbonate rocks. Reservoir rocks are rocks that have sufficient porosity and permeability to store and transmit fluids and gas.
