| Abstract | ||
| A geological model was constructed using Petrel software for the Yamama Formation in the Siba oil field, southern Iraq. Information from four drilled wells in the area was used to define water saturation, porosity, and permeability. In addition, well-log data including sonic, density, neutron, gamma-ray, spontaneous potential (SP), and resistivity logs readings were used to determine the petrophysical properties of the formation. This work aims to study the occurrence of potential oil zones within the formation. Results indicate that zone 1 has low water saturation, high porosity, high permeability, and a high value of net to gross. For instance, the average porosity of the reservoir in Zone 1 is approximately 7.33%, compared to only 2% in Zone 2. Additionally, Zone 1 has a permeability value of 7 mD compared to only 0.2737 mD for Zone 2. Finally, Zone 1 has a water saturation value of 63%, while Zone 2 has a saturation of 89%. Based on the collective analysis of these factors, it was concluded that Zone 1 is more favorable for hydrocarbon development and production than Zone 2. Therefore, these findings can be valuable for optimizing well placement, production strategies, and overall reservoir development planning for oil resources. | ||
