What is it about?
This study investigates how to use post-processing seismic-data conditioning to improve the interpretation of seismic-reflection data in western offshore Libya. The study shows how using a structure-oriented filtering technique can help visualize subsurface reflection features more clearly and detect subtle geological features, such as faults, Furthermore, filtering increases the lateral continuity of individual seismic reflectors, which can help with horizon auto-tracking interpretation.

Why is it important?
The proposed filter-based workflow is compatible with most seismic interpretation software packages and is recommended as a standard procedure prior to structure-attribute calculation and structural interpretation on low-quality seismic-reflection data. The study's findings indicate that seismic-data conditioning can strongly enhance the visualization of subsurface reflection features
Perspectives
This study highlights the importance of post-processing seismic-data conditioning in enhancing subsurface imaging and improving the accuracy and resolution of geological and geophysical understanding, ultimately leading to better drilling and production decisions, and can be applied in most seismic interpretation software packages as a standard procedure.
