Petroleum geology is the study of the origins, occurrence, movement, accumulation, and exploration of hydrocarbon fuels. It refers to the specific set of geological disciplines that are applied to the search for hydrocarbons ( oil exploration ).

Anticlinal trap. An anticline is an area of the subsurface where the strata have been pushed into forming a domed shape. If there is a layer of impermeable rock present in this dome shape, then hydrocarbons can accumulate at the crest until the anticline is filled to the spill point (the highest point where hydrocarbons can escape the anticline).

Petroleum, or evidence of its immediate occurrence, can be found on the surface of the Earth. Oil seeps can be found near a fault zone, where the movement of Earth's crust can expose petroleum source rock, and thus the crude oil itself. [15] They can also be found on the ocean floor, and can be found using satellite imaging. [16]
The journal was established in 1963 as Petroleum Geology Experiment Abstract (Chinese: 石油地质实验文摘) and renamed Experimental Petroleum Geology (Chinese: 石油地质实验) in 1965. [ citation needed ] In 1966, the journal ceased publication after three issues, but resumed publishing in 1978. [ 3 ]
A petroleum geologist is an earth scientist who works in the field of petroleum geology, which involves all aspects of oil discovery and production. Petroleum geologists are usually linked to the actual discovery of oil and the identification of possible oil deposits, gas caps, or leads. It can be a very labor-intensive task involving several ...
In the petroleum industry, lithology, or more specifically mud logging, is the graphic representation of geological formations being drilled through and drawn on a log called a mud log. As the cuttings are circulated out of the borehole , they are sampled, examined (typically under a 10× microscope) and tested chemically when needed.
In petroleum geology, source rock is rock which has generated hydrocarbons or which could generate hydrocarbons. [1] 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.
