A doctoral thesis at the University of Basra examines the structural pattern and tectonic evolution of the Zubair oil field in southern Iraq

A doctoral thesis at the Faculty of Science at the University of Basra examined the structural pattern and tectonic evolution of the Zubair oil field in southern Iraq. 

The thesis, submitted by student Ayman Adel Lazim, aimed to conduct a structural and tectonic analysis of the Zubair oil field in order to identify fault and fold patterns and determine whether they have an impact on the distribution of the field's reservoir properties. 

The study included a detailed structural geological analysis of the faults and folds of the four domes—Al-Hammar, Al-Shuaiba, Al-Rafidiya, and Safwan—within the Zubair oil field and proposed a tectonic model for the field from the Jurassic period to the present. 

The results showed that the Zubair oil field contains numerous faults extending across the four domes. Folding processes have been ongoing since the Pre-Jurassic period to the present day. The causes of the formation of faults and folds are attributed to the role of the Hormuz salts, the activity of the base faults, and the collision between the Arabian and Eurasian plates. These faults and folds may have affected the distribution of oil in the field.
