Marine petrogeology, often abbreviated as "mar pet geol", is an interdisciplinary field that focuses on studying the geological aspects of marine petroleum systems. This area of research encompasses various disciplines, including geology, geophysics, geochemistry, and sedimentology, to understand the processes involved in the formation, migration, and accumulation of hydrocarbons in marine environments. Synonyms for "mar pet geol" include marine petroleum geology, marine hydrocarbon geology, and offshore petrogeology. These terms all reflect the same core concept of investigating the geological factors influencing the presence and distribution of oil and gas reserves within marine sedimentary basins.
