... method. The block models were used for spatially constraining 3D geo-cellular DFN models. The fracture centers within the DFN cellular grid are controlled by the cellular P 32 values, estimated using the 3D block model. The joints orientation was bootstrapped from drillhole loggings whereas trace length...

The first approach consists of the analysis of faults picked from 3D seismic volume and the second comprises the analysis of the sub seismic faults digitized from different seismic attributes and wellbore imagery analysis. Two trends of faults are highlighted and separated by a syncline oriented in the same...
