Hydrocarbon exploration (or oil and gas exploration) is the search by petroleum geologists and geophysicists for deposits of hydrocarbons, particularly petroleum and natural gas, in the Earth's crust using petroleum geology.
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 ).
A lead in hydrocarbon exploration, is a subsurface structural or stratigraphic feature with the potential to have entrapped oil or natural gas. [1] When exploring a new area, or when new data becomes available in existing acreage, an explorer will carry out an initial screening to identify possible leads.
Geophysicists and exploration geologists who look for oil and gas fields classify the subsurface characteristics, or tectonic setting, of geological structures that contain hydrocarbons. Any one oil and gas field may reflect influences from multiple geological periods and events, but geoscientists often attempt to characterize a field based on ...
Sequence stratigraphy is and essential tool in the application of geology to the exploration for oil and gas, as a part of the field of Petroleum geology. Much of the development of this scientific discipline has occurred within or been funded by energy corporations and their geological research labs. [3] [4]
In geology, a petroleum play, or simply a play, is a group of oil fields or prospects in the same region that are controlled by the same set of geological circumstances. [1] The term is widely used in the realm of exploitation of hydrocarbon-based resources. The play cycle normally exhibits the following steps:
The Faroe-Shetland Basin is a sedimentary basin formed by mainly Mesozoic rifting that lies between the Faroe Islands and the Shetland Islands. [1] It has been the site of hydrocarbon exploration since the 1960s, with many significant oil and gas discoveries, including the Clair oilfield, which had an estimated 8 billion barrels of oil in place before production started, [2] the Schiehallion ...
Exploration geophysics is also used to map the subsurface structure of a region, to elucidate the underlying structures, to recognize spatial distribution of rock units, and to detect structures such as faults, folds and intrusive rocks. This is an indirect method for assessing the likelihood of ore deposits or hydrocarbon accumulations.
