Abstract: Conventional oil resources are no longer sufficient to cover all of the world’s need, as oil demand increases with time. Therefore, the oil industry is gradually converting to producing from unconventional resources i.e. heavy oil. Heavy oil requires enhanced oil recovery methods in order to be produced within reasonable amounts and simultaneously to meet the market rate. Heavy oil existing in carbonate reservoirs is estimated to be over 1.6 trillion barrels worldwide. Several methods have been tested to identify the ideal approach to produce heavy oil from carbonate reservoirs since they are known for their great heterogeneity. Thermal recovery method has shown its success in heavy oil production matter. The purpose of this research is to examine the thermal recovery efficiency in delivering heavy oil in a heterogeneous carbonate reservoir. In order to accomplish that, a reservoir simulation model is created using CMG and 5 different cases are constructed. Those 5 cases are different with respect to their variation of permeability fields. Several cases resulted from studying various fluid injection scenarios and various oil viscosities systems on different permeable fields. Moreover, sensitivity data analysis method is applied for investigating the impact of different sensitive parameters on heavy oil recovery. Eventually, a comparison procedure will be performed to feature the optimum scenario where heterogeneity plays a minor role in impeding higher heavy oil recovery.
