Characterization of Reservoir Heterogeneity Using Inverse Model Equipped with Parallel Genetic Algorithm

Development of Inverse Model for Reservoir Characterization Using SA Algorithm

“…The comparison of the result of the inverse calculation performed by GA (Kwon et al, 2007) with this research under the same reservoir system and conditions showed that SA had been similar to GA by pressure matching result as listed in Table 5. Therefore SA algorithm consuming less memory than GA could obtain good result.…”

“…4. Three-layered heterogeneous reservoir system (Kwon et al, 2007). is required to escape from the local optimum.…”

“…This Paper developed an inverse model investigating the heterogeneity of permeability and porosity by combining SA algorithm and forward simulator. The forward simulator (reservoir simulator) used for the inverse model was multi phase and three-dimensional black oil simulator called HYBOS of which performance was verified by Kwon et al (2007).…”

“…The reservoir system used for analysis was the heterogeneous reservoir consisting of three layers which was applied to the paper issued by Kwon et al (2007). 4 producers and 7 water injectors were placed on 3 layers consisting of 300 (20 x 15 in x, y respectively) grids (Fig.…”
