| Abstract | ||
| Permeability and porosity are the most difficult parameters to estimate in the oil reservoir because they are vary significantly over the reservoir especially in the carbonate formation. Porosity and permeability can only be sampled at the well location. However, porosity is easy to estimate directly from well log data, but permeability is not. In addition, permeability measurements from core sample are very expensive. Carbonate reservoir is very difficult to characterize because of their tendency to be tight and heterogeneous due to deposition and diagenetic processes. Therefore, many engineers and geologists try to establish methods to get best characterization for the carbonate reservoir. In this study, available routine core data from three wells are used to develop permeability model based on Hydraulic Flow Unit Method (RQI/FZI) for one of the Iraqi carbonate oil reservoirs. The results show that the HFUM is work perfectly to characterize and predict permeability for un-cored wells because the R2≥0.9. It is indicating that permeability can be accurately predicted from porosity if rock type is known. | ||
