In this study, geochemistry analysis of oil and source rock extracts from different fields of Basra and Amara oil fields is implemented. Results indicate that the type of producing oil rocks are marine algae carbonate type II rocks and no contribute from terrestrial sources. These rocks are deposited under marine environment (> 150 m deep) and have normal saline and reduced conditions. No biodegradations are observed in the studied oil. The correlation of oil–oil exhibits that the oils have the same group and family and back to the same rock. On the other hand, the correlation between oil and source rock demonstrates that both of them have the same geochemical characteristics. The results of isotopic analysis of oil show so that source rocks of oil are marine mature rocks and have high sulfur content with API in range (15–48).
