What is Petroleum Geology ?

Petroleum geology is general geology with a specific aim and all these things apply to petroleum geology. The petroleum geologist’s work also has its descriptive and interpretive aspects, but the emphasis tends to linger on the descriptive because the goal of petroleum geology is a deterministic model of the area under study - ultimately, the oil or gas field. Petroleum geology is the study of origin, occurrence, movement, accumulation and exploration of hydrocarbon fuels. It refers to the specific set of geological disciplines that are applied to the search for oil and gas exploration).
