Abstract

History matching between reservoir simulation results and actual production data is essential for determining a reservoir^s production potential. However, this process is particularly difficult for carbonate reservoirs due to their heterogeneous rock formations.

In earlier research on the ^B^ gas field, which contains carbonate reservoir rocks, modeling was performed using a reservoir facies division method based on lithology types such as grainstone, wackestone/packstone, and mudstone. This lithology-based approach posed difficulties during the history matching stage of the simulation.

In this study, the author aims to introduce a rock classification analysis method for the carbonate reservoirs in the ^B^ gas field using the hydraulic flow unit (HFU) technique. This method will be applied as the basis for history matching, with the goal of improving the accuracy of the results.
