Reservoir Characterization and Rock Typing of Carbonate Reservoir in the Southeast of Iraq

The Iraqi Geological Journal, 2023
Flow unit and reservoir rock type identification in carbonates are difficult due to the intricacy of pore networks caused by facies changes and diagenetic processes. On the other hand, these classifications of rock type are necessary for understanding a reservoir and predicting its production performance in the face of any activity.
