Deep-water hydrocarbon accumulation conditions and exploration target in the Eastern Mediterranean

doi:10.3969/j.issn.1672-7703.2021.03.010

Abstract

Abstract: The eastern Mediterranean has become one of the global hot spots of deep-water oil and gas exploration in recent years owing to its abundant oil and gas resources and low degree of exploration. The study of deep-water hydrocarbon enrichment conditions in the Eastern Mediterranean is of guiding significance to the selection of exploration zones and plays in this area. This paper analyzes the tectonic sedimentary evolution, petroleum geological conditions, reservoir-caprock assemblages, and hydrocarbon accumulation characteristics of the Eastern Mediterranean and discusses the deep-water hydrocarbon enrichment conditions and exploration targets by comprehensive petroleum geological study on the international oil and gas commercial database and geological and geophysical data. The results show that there are two main reservoir-caprock assemblages of Miocene reef limestone + salt rock and Miocene turbidite sandstone + salt rock, and two inferred reservoir-caprock assemblages of Cretaceous turbidite sandstone + shale and Jurassic reef limestone + marl in the Eastern Mediterranean. The deep-water hydrocarbon enrichment in the Eastern Mediterranean is controlled by thick Oligocene-Miocene marine source rocks, high-quality Miocene basin floor fan turbidite sandstone and reef limestone reservoirs, regional salt caprocks and large structural traps developed during the tectonic inversion period. In the future, favorable plays of Miocene turbidite sandstone in the deep-water area in the Levant Basin and Miocene reef limestone around the Erotosthenes platform should be focused on, and new fields of Miocene turbidite sandstone in deep-water area in theHerodotus Basin and deep Mesozoic in the Levant Basin be further explored.

Key words: reservoir-caprock assemblage, hydrocarbon accumulation, exploration target, deep-water, Eastern Mediterranean
