Abstract

This chapter focuses on the hydrocarbon habitat of the Greater Arabian basin. There is an obvious subdivision of hydrocarbon habitats in the Middle East into the basins lying primarily on the Arabian Platform and those in the Zagros Basin. On the Arabian Platform, concern is primarily with Jurassic and Cretaceous source rocks and reservoirs, and secondarily with Paleozoic sources and reservoirs; in the Zagros Trough, the traps and reservoirs are mostly Cenozoic and are the result of late Cenozoic tectonism. As the Cenozoic tectonic activity resulted in the formation of the Zagros Foredeep/Basin, it is not surprising that this resulted in the implantation of younger basins over the edges of the Arabian Platform. The chapter reports that the greatest proportion of the Middle East oil and gas reserves and resources are found in the Arabian Basin. The Paleozoic to Middle Miocene sequence in the Arabian Basin is the world's richest hydrocarbon province. Also, large volumes of non-associated gas are housed in the Paleozoic sequence of central and eastern Arabia.
