Abstract
The comprehensive reservoir study for the First and Second Bahrain Sand reservoir has been performed utilizing the existing simulation models. But it has been realized that the models do not have sufficient capability to predict the detailed water flow behavior and hence water production performance partly because the available models were constructed using the relatively simplified geological models and partly because fluid flow behavior has not been fully examined. In order to improve calculation accuracy and predict water production performance accurately, therefore, it was decided to construct new reservoir simulation models for both reservoirs based on the newly evaluated detailed geological models.
To construct the detailed geological model, the concept of the sequence stratigraphy and sedimentological log facies analysis were applied to the interpretation of the frequent lateral lithological changing fluvial complex.
Before re-constructing full-field models, the regional model study to construct a sector model which covers about 2km×4km area in southwest part of Second Bahrain Sand reservoir was performed in order to recognize how fine grid model based on the detailed geological model can simulate formation water behavior.
This report describes the regional model study.
