Reservoir Model for an Iraqi Oil Field
Abstract
The research creates a reservoir model for an oil field based on data from 15 exploration wells in the region.The major goal of the paper was to assess the initial oil in place value and to evaluate the difference between initial oil in place that is calculated by volumetric method for the reservoir and dynamic models before making a final investment decision for the oilfield's further development.
The log readings were interpreted and calibrated with the core data. The software Interactive Petrophysics (IP) was used for log interpretation. A geological model for the Mishrif layer in this reservoir was created, based on the interpretations of the log readings analysis, laboratory measurements of the fluid properties, and core reports for fifteen well. This was followed by the creation of a reservoir model to represent the movement of fluids through the reservoir and the consequent change in reservoir pressure. The PETREL platform (v.2017) platform was utilized to construct the model.
The mismatch between the initial oil in place that is calculated by the static and dynamic models was 0.3 % which indicates good match since maximum acceptable mismatch is 1%.
The reservoir has large initial oil in place, according to the findings of geological and dynamic models. The importance of developing this oilfield is verified by its very high IOIP.
