Abstract
The article presents the results of planning the development of naturally fractured carbonate reservoir, considering the features of its geological structure
Aim. The work was aimed at improving the forecast of the geological structure and production using the static and dynamic model.
Materials and methods. Standard input data for geological modeling and microimagers were used as initial data; the dynamic model was adjusted based on the results of well testing and production testing. A fracture network model was built, fracture permeability was calculated, which then helped to adjust permeability in dynamic model.
Results. The resulting fracture permeability map was successfully used when history matching the dynamic model. According to the results of the dynamic model calculation, an improvement in history matching and the absence of unreasonable changes in permeability multipliers are observed.
Conclusion. The obtained results confirm the improvement of the dynamic model forecast and the preservation of moderate computing time when using this approach.
