The Department of Geology, College of Science, discussed a Ph.D. thesis entitled (Fourthographic and Biostratigraphic Architecture of Al-Fath Formation of Selected Fields in Southern Iraq). The researcher Najed Faisal Sharif's thesis aims to aim at an integrated study in terms of sedimentation and fossils, building an architecture that forms formation layers, and drawing a sedimentary model for it.
The study included collecting data from the Basra Oil Company and university studies and dissertations on the subject, making thin slices of the formation layers as well as fragmenting models for the purposes of capturing fossils using multiple chemical methods, describing the probes and matching them with the results obtained from the thin slices in order to reach an integrated sedimentary model for the formation of the hole and a broad statistical comparison. Wells are under study to facilitate knowledge of the environment for formation sedimentation.

The results revealed that a group of fossils were diagnosed, which are forty-two species of Foraminifera belonging to twenty-one genera, forty species of Ostrakoda belonging to thirty sexes, in addition to twenty species of Castropoda belonging to nine genera, and three species of algae belonging to three genera and one sex for each of the echinoderms. , golden algae and green algae. Based on the stratigraphic distribution of the genera Foramenfera and Ostercauda, ​​my range is one of the foramenfera.
