fault 07

 

Thanks to interactive picking tools, fault patches can be quickly picked and merged in a semi automatic workflow by filtering according to azimuth and dip. Combined with structural attributes either based on the seismic or the geologic time model, subtle faults and fractures can be imaged and interpreted in 3D.

Faults represent a key role in the reservoir exploitation plan, their properties (leakage/sealing) is crucial for every well placement decision or in the life cycle of the production field.

Fault interpretation remains a crucial step to minimize risk in any well placement. Thanks to the advances in seismic acquisition, it becomes now possible to image faults and fractures. However, fault plane exteaction remains a tedious task, which has to be realized manually.

For these reasons, advanced editing tools to pick and edit fault sticks, create patches and merge them, within a semi-automatic workflow , are proposed. Thanks to Interactive and intuitive tools such as real time preview of fault plane, undo redo, dip/azimuth filtering, this technique enables interpreting dense and complex fault networks, in a limited time frame.

By inserting fault planes to the geologic time model, fault throw distribution can be mapped on each plane, which helps in the understanding of sealing and geomechanical properties.
