The naturally fractured reservoirs play very important role in hydrocarbon production within Panonian basin. The well production crucially depends on the possibility to penetrate the fractured zone Fracture network cause significant anisotropy of rock properties which, in turn, could be studied with a combination of seismic and wellbore data. AVAZ inversion and full-wave acoustic logging coupled with borehole images were implemented to estimate fracture parameters in order to predict zones of high productivity. The independent techniques revealed differences in estimated fracture direction. Discovered descrepancies are explained by different scales of the applied methods and should be taken into consideration during well planning.
