Petrel structural interpretation

Fast, accurate structural interpretation workflow that reduces interpretation uncertainty and delivers a confident, validated structural framework of the subsurface

Overview

Petrel™ structural interpretation 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 to reduce interpretation uncertainty and deliver a validated structural framework of the subsurface.

Seismic reconstruction with chronostratigraphic sections and quick-look understanding of geomechanical processes.

Benefits

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.
