  6. Arabian Basin Traces a polyhistory of plate tectonic & sedimentary fill: • Pre Cambrian to Infra-Cambrian - Continental interior • Silurian and Ordovician clastics – Continental interior • Permian clastics & carbonates – Trailing margin • Upper Jurassic Carbonates – Trailing margin • Lower Cretaceous Carbonates – Trailing margin • Middle Cretaceous – Compression & Zagros Mts initiated • Tertiary Carbonates and Clastics - Compressional margin

  7. Oil Production - Arabian Gulf Productive hydrocarbon section older to West [Paleozoic] & younger in East in the Zagros Mts [ Upper Tertiary]. West to East production includes: • Infra-Cambrian Salt • Silurian and Ordovician clastics – Unaizah • Permian clastics & carbonates – Khuff • Upper Jurassic Carbonates - Arab & Tuwaik Mt Group • Lower Cretaceous Carbonates – Shuaiba & Thammama • Middle Cretaceous – Mishrif • Tertiary - Asmari

  11. Arabian Gulf tracks the Wilson Cycle • Plate tectonic theory divides earth’s crust into plates • Plates diverge apart or rift & a new ocean basin forms • Plate motion reverses & convergence causes collision, & mountain building • The Wilson Cycle records plate motion opening & closing of ocean basins in the rock record

Sedimentary Section is Source Collister, James, Robert Ehrlich, Frank Mango, and Glenn Johnson (2004), Modification of the petroleum system concept: Origins of alkanes and isoprenoids in crude oils AAPG Bulletin, v. 88, no. 5 pp. 587–611Establish that the source of petroleum was once dispersed through much of the sedimentary sections and not necessarily from classic organic rich source rocks.
