Abstract
Fracture distribution in a naturally fractured reservoir is related to many different parameters. These parameters include fracture drivers such as tectonic phenomenon, fracture controllers such as lithology and porosity and fracture indicators such as mudloss and production data. Each of these parameters is related to fracture distribution in a specific point of view. This study is focused on Asmari Formation in Gachsaran oil field is which is the most famous naturally fractured reservoir in Iran. The main goal of this work is comparison and integration of all of the fracture signs and controller parameters to generate a comprehensive fracture intensity model. 3D strain is calculated and integrated in fracture intensity modeling as a tectonic fracture driver. Distance to fault was also contributed as a second driving factor to the modeling process. On the other hand, the mudloss was normalized and converted to fracture permeability and its 3D model was generated to be added in the intensity modeling. Productivity Index map was another indicator that was involved in modeling. The result fracture intensity model includes the effect of all of the fracture controllers, drivers and indicators and this is the main advantage of integration approach for modeling.
