Illumination Analysis Defining Better Acquisitions and Processing Strategies

Subsurface seismic imaging starts at data acquisition. This means that subsurface illumination is directly linked with the acquisition system. The full wave propagation modeling algorithm is the most proper tool to perform illumination analysis of complex structures, giving results not provided by approximated methods, such as Ray Tracing.


Due to its complexity, subsalt seismic illumination is a challenge even using the most advanced seismic acquisition and imaging technology. An illumination study can reduce exploration risk by identifying shadow areas and testing acquisition scenarios that lead to optimum image quality.

Observing the illumination analysis importance, PETREC can provide solutions through Optimized Full Waveform Modeling to perform illumination and visibility analysis, helping the acquisition and data processing strategies.
