Abstract:
An integrated approach to the study of fault patterns carried out in the complex geological
structures of Bualawn, Dor Mansour fields by using multiple seismic attributes of 3-D seismic
data. Each type of geological structure event usually generates a unique seismic signature that
can be recognized and identified. This paper highlights the practical importance of analyze integrated attributes and interpret them within the context of an appropriate structural deformation. Many of discontinuity attributes such as variance, 3DEE (3D edge enhancement), ant
tracking, chaos and structure smoothing have been selected to delineate fault styles and their
displacement effectively, which cannot be fully delineated using seismic amplitude data. Conjugate growth faults in NW-SE and NE-SW direction, dipping toward SW with antithetic faults
dipping in opposite direction to the growth faults and other minor faults. The faults were identified manually and then tested by discontinuity attributes. Fault system is represented by a
fracture system comprising long en echelon seismic faults and several discontinuities. This system of en echelon faults was initiated by left-lateral wrenching movements. This wrenching
system has been identified by negative and positive flower structure along the releasing and
restraining bends. The current understanding that these faults are strike-slip faults despite the
absence of extensive horizontal displacements along them as shown on different time slices. A
periodic strike-slip movement along deep-seated basement faults have developed many structural features, such as horst-graben styles, which is the orientation of the transtensional movements linked to the Upper Cretaceous Succession
