Naturally fractured reservoir differs frorn clastic reservoirs in the sense that the con-cepts of porous media which were usually applied for clastic reservoir analysis rnust bemodified. This means that handling naturally fractured reservoir is also different com-pared to handling clastic reservoir. The porosity may be changed a bit bigger but thepermeability is drastically changed. Also at a depth where rock layers are usually tight,naturally fractured reservoirs converts it to become a good reservoirs. Naturally fracturedreservoirs can be found in sorne part of the Indonesian basin which may contribute aconsiderable additional reserves in the near future.
