Petroleum Systems of Iraqi Oil Fields

Abstract

Oil and gas fields in Iraq are distributed in geographic locations with giant oil fields toward the east and giant gas field toward the west of Iraq, except Diala region that have separated gas and oil fields in the north east. Farther more, their reservoirs are scattered in stratigraphic successions. On the basis of Crude oil analysis mainly by GC, GC/MS, source rock assessments mainly by pyrolysis analysis and palynofacie, structural cross and seismic sections, as well as petrophysical properties and PetroMod software basin modeling; Iraqi oil accumulations could be grouped into varieties of total or formational petroleum systems. These petroleum systems could be used for hydrocarbon exploration and for mineral genesis through systematic studies and analysis in the proposed oil field.
