The Department of Earth Science at the College of Science organized a seminar entitled Characterization of naturally fractured carbonate reservoirs: a case study of the Rumaila oil field - southern Iraq. The seminar, attended by researcher Nour Al-Huda Qasim Abdul Hussein Al-Mohsen, aims to characterize and identify fractures that occur naturally within the Mushrif Formation. The study included the use of a multi-methodological approach integrating core and thin-slice analysis, seismic data, well image logs, and conventional well logs. The results revealed different types of natural fractures, such as open, filled, zigzag, and propped fractures.The results revealed different types of natural fractures, such as open, filled, zigzag, and propped fractures. The field is dominated by the open type, so the potential for oil production from this formation is high. Analysis of the direction of fractures revealed that the northwest and southeast directions contain the largest percentage of fractures, making these areas suitable for drilling more wells.
