Structural smoothing was applied to reduce background noise and sharpen discontinuities in the seismic volume, then variance attributes and ant-tracking were used to highlight sharp discontinuities. We then use...

Our novel workflow provides a practical tool to perform fast forward modeling...

... discontinuity enhancement and skeletonization methods enhances fault discontinuities and suppresses many non-fault discontinuities. Although each fault is characterized by its dip and azimuth, these two properties are discontinuous at azimuths of φ =±180° and for near vertical faults for azimuths φ and φ...

... Diffractions are the seismic response of subsurface geological discontinuities, and thus, carry detailed geological information in 3D seismic exploration. It is a challenge to separate weak diffractions from specular reflections, especially when they have similar kinematical characteristics...

... unstable or stable in present stress state. A pre-existing discontinuity, i.e. fault or fracture, will re-activate when the shear strength on the fault/fracture plane is exceeded i.e. slippage occurs along the discontinuity. The discontinuity is then referred to as unstable. If the shear strength...

Another positive aspect is the higher lateral continuity of the discontinuities, which looks more rectilinear and uniform when using the full azimuth stack volume. Local improvements obtained with individual...
