This reference is for an abstract only. A full paper was not submitted for this conference. Plynomorph constituents and their maturation, rock oval pyrolysis, total organic carbon (TOC) analysis are carried on for the whole succession of the Upper Jurassic and the Cretaceous Formations of Iraq. These lines of analysis have been used in this study to evaluate correlation between oil of Khasib reservoir rocks and kerogen of the source rocks as well as suggestions for oil traps along the predicted migration path in East Baghdad oil Field. The gas chromatography of these oils can show biomarkers of abundant ranges to suggest mainly liquid oil constituents of parafinic hydrocarbons in the reservoir as well as low non aromatic C15+ peaks to indicate their degradation and water washing. Oil biomarkers and CPI=1.5 could indicate anoxic marine environment with carbonate deposition of early Cretaceous source. The recorded palynomorph constituents in this oil and associated water could indicate affinity to the Lower Cretaceous Chiagara and Ratawi Formations. The recorded palynomorphs from the reservoired oil are comparable to the mature palynomorphs of Chiagara and Lower part of Ratawi Formations that had generated hydrocarbons according their TOC, high hydrogen potential, mature kerogen type II and palynofacies of high generating potential for oil, while the palynomorphs of the rocks of Khasib Formation are not generated hydrocarbons. But, this last formation could be considered as oil reservoir only. Accordingly, these palynomorphs have been included in this oil during its generation from the Kerogen source of the Chiagara and Ratawi Formations, and hence been migrated within the liquid hydrocarbnos to the Khasib Formation through fractured fault passageway shown on the seismic section in Baghdad Oil Field. The increasing Pristane/ Phytane ratios to more than one, increasing migration index up to 0.9 and microfractare of the source rocks could confirm their migration.
