NITEC has had the opportunity to evaluate numerous naturally fractured reservoirs over the years.

This type of reservoir requires special technologies to characterize the fracture/matrix system in the static and dynamic models, along with particular expertise in the model calibration (history match) process. NITEC has developed technology within its LYNX software to identify the fractures at the wellbore using conventional well log tools and then estimate the distribution of the fractures through the formation flow units using a modified structure curvature analysis technique. This approach provides excellent agreement with image logs at the wellbore and a quantifiable basis for the initial fracture distribution estimate in the simulation model. This approach has been used in a number of sandstone and carbonate field studies throughout the world. Many fractured reservoirs that were characterized by this workflow have been successfully history matched over the years. Details of this workflow can be found in SPE 53860 and SPE 84413.

NITEC has developed a systematic approach to evaluating the properties of the natural fractures and the interaction between the matrix system and the fractures in the dynamic modeling. The proper quantification of these fracture parameters in the simulation model can be critical to a successful history match and subsequent predictions.
