The Levantine Basin and the Levant Margin
The Levantine Basin, a deep marine basin with water depths of 1,500 – 2,000m and an area of 83,000 km2 , is one of the world’s significant underexplored regions. It is the only basin in the eastern Mediterranean where deepwater offshore wells have been drilled. Industry faith in this offshore area as an exploration target has been justified in recent years by three significant finds; Tamar, Dalit and most recently Leviathan. These have proven the existence of good (sub-salt) reservoir sands within the Miocene strata.
The Levantine Basin has been in existence since the Late Palaeozoic, and is believed to contain a thick infill of sediments. The Levant Margin is a passive continental margin located to the east of the Levantine Basin, which has persisted since at least the Mesozoic and today comprises a narrow marine shelf and a broader terrestrial area. A variety of processes have influenced the development of the margin and the thick sedimentary succession deposited. These sediments are predominantly shallow marine and include carbonates, marls and clastics in which hydrocarbons are proven to be present.
Interpretation of regional seismic data has greatly improved the understanding of the stratigraphy of the Levantine Basin. Key horizons have been interpreted and used to produce time and depth grids and the interpreted horizons can be seen to separate distinct seismic sequences with particular seismic characteristics.
