This study includes a palynological and organic geochemical study of Nahr Umr, Zubair, and Yamama Formations in the Subba field, southern Iraq represented by the wells (Su-14, Su-9, and Su-8).
These analyses include the determination of quantity organic matter; which indicate is that, the rocks of Nahr Umr Formation are very good rocks for the production of hydrocarbons and its kerogen of type (II) is dominant, but thermal immaturated, while the ability of the Zubair Formation for the production is good to very good and its kerogen of type (I &II/III) is dominant, and low thermal maturity, and the ability of Yamama Formation is good for the production of hydrocarbons, and the kerogen of type (I) is dominant, and low thermal maturity.
Facies analysis of Nahr Umr, Zubair, and Yamama Formations shows the presence of two facies , they are : 1) Distal dysoxic – Oxic shelf.
2) Distal suboxic – Anoxic basin.
It is clear that the environment of rock deposition is a marine environment far from the coast.
The geochemical analyses of the crude oil accumulated in Nahr Umr, Zubair, and Yamama Formations in wells (Su-14, Su-9, and Su-8), the ratios of biomarkers which are related to their age are studied, such as, ratios: OL/H, C28/C29 and indicate Middle Triassic - Upper Jurassic age and Upper Jurassic - Lower Cretaceous age.
But the biomarkers related to maturation, such as, Ph/nC18 and Pr/nC17 shows that the crude oil is thermally mature in the Yamama, and Zubair Formations .
The biomarkers and non-biomarkers related to the source, such as, the ratios : Tet/C23, C28 /H, Pr, Ph and CPI indicate that the source rocks of the Yamama, and Zubair Formations are carbonates or carbonates interfered with shale or marl deposited in anoxic marine environment with normal salinity and kerogen type (II) of algal origin, matured and did not undergo a biodegradation process .
On the other hand, analyses of carbon isotopes, such as, the ratios δ13C%, δ13Caro, δ13Csat, and Pr/Ph indicate that the previous conclusions are the same for biomarkers and non-biomarkers.
It is clear from the above results that the crude oil accumulated in Nahr Umr, Zubair, and Yamama Formations are from Middle Triassic - Upper Jurassic source rocks and the most important of them is Geli Khana and Sargelu Formations.
