The College of Engineering at the University of Baghdad held a public discussion for master candidate (Farah Ahmed Radhi) in the Department of Petroleum Engineering regarding her dissertation titled:
Reservoir Characterization and 3D Modeling of Mishrif Formation / Ratawi Oil Field
The discussion took place on Monday, October 7, 2024, in the Graduate Hall of the Petroleum Engineering Department, under the supervision of Associate Professor Dr. Omar Falih Hasan. The examination committee consisted of the following professors:
1. Prof. Dr. Ayad A. Alhaleem A. Alraazzaq (Chair)
2. Asst. Prof. Dr. Dahlia A. Al-Obaidi (Member)
3. Dr. Hussain Ali Baker (Member)
4. Asst. Prof. Dr. Omar Falih Hasan (Member and Supervisor)
Objective of the Study
The study focused on determining the petrophysical properties of Mishrif formation, which is one of the most promising carbonate reservoirs and very heterogeneity in the Ratawi oil field, by logs interpretation of ten wells in the Ratawi field; characterize the reservoir to understand the distribution of fluids and formation properties; and also calculate the initial oil in place (OIIP) by building a three-dimensional geological model.
Conclusion
Mishrif formation had been characterized using different methods, which were: Flow Zone Indicator (FZI)characterized four hydraulic flow units; Winland (R35) identified three pore throat types; Lucia classification described three groups of rock fabric number (RFN); and Cluster analysis determined five electrofacies. Five rock types were identified for Mishrif formation by integrating these methods.
The permeability of uncored wells was predicted using the FZI approach, which showed the best matching with core data (R^2=0.93) from other methods, which were: multi-regression, Winland (R35) and Lucia classification
