Introduction

The Practical Depth Conversion and Depth Imaging for the Interpreter training program is a specialized, application-oriented course designed to enhance the technical and interpretative capabilities of geoscience professionals involved in subsurface interpretation. The program focuses on bridging the gap between time-domain seismic interpretation and accurate depth-domain understanding, which is critical for reliable structural mapping, reservoir delineation, and well planning.

This training program is designed and delivered by Global Horizon Training Center, leveraging industry best practices, practical workflows, and real-world interpretation challenges. The course emphasizes practical depth conversion methodologies, velocity modeling concepts, and depth imaging techniques that interpreters encounter during exploration and development phases. Through guided exercises, case-based discussions, and applied workflows, participants will gain confidence in producing defensible depth models and interpreting depth-imaged seismic data for decision-making.
