Miocene Channel Geometries from High Quality 3D Seismic Onshore Giant Oil Field in Middle East

Abstract

During shallow drilling hazards seismic mapping campaign, several Miocene age channel geometries were interpreted as transgressive and high stand systems tracts formed from Langhian to Serravallian. Channel geologic pattern from north-east to south-west direction, suggests they were formed along unstable shelf tectonic setting of southern Iraq during Miocene, where transgressive-regressive sequence in a broad shallow foreland basin adjacent to the Zagros-collision belt. Depositional environment ranged from open-marine to supratidal and continental sabkha, fluvial-deltaic and exposure.
