Structural modeling

Structural modeling has become increasingly important for complex structures, geomechanical studies, petroleum systems, and seismic imaging. Modeling is important not just within the reservoir zone, but for the entire basin, or as a full field from overburden to reservoir aquifer, and often down to the basement. During seismic interpretation a structural framework is built, consisting of a fault framework and a zone model.

In complex geologic settings, sound structural modeling and analysis are essential in understanding the deformation and stress history of the basin or prospect. iOG offers expert solutions in structural modeling and analysis through several of our senior associates who are recognized for their expertise in structural geology and stress analysis.
