Petrel Structural Interpretation

Structural interpretation in the Petrel E&P software platform improves the understanding of structure and delineation of fault and fracture networks through various advanced edge detection and illumination attributes (including Ant Tracking). Tectonic and depositional relationships can be understood through interactive 2D seismic reconstruction (structural flattening), based on geomechanical principles. Linked with modeling-while-interpretation capabilities, this provides a powerful tool for fast and accurate fault interpretation, reducing interpretation uncertainty and delivering a validated structural framework of the subsurface.

Detailed reservoir understanding

Advanced edge detection and illumination attribute workflows (including ant tracking) can be used for enhanced structural delineation, or as input to fracture modeling. Additionally, interpreters can easily understand the trends of fault surfaces and automatically extract fault patches, instead of creating fault surfaces individually and manually—significantly reducing conventional interpretation time.
