About this program

Seismic techniques rank among the most effective methods for visualizing the Earth's subsurface and are essential in petroleum, mineral, and geotechnical exploration. This Seismic Data Analysis and Interpretation Training Course offers a comprehensive workflow covering seismic acquisition, processing, and interpretation aimed at geological and exploration objectives. Participants will acquire hands-on understanding of seismic data quality, velocity modeling, structural and stratigraphic interpretation, as well as the integration of seismic information with other subsurface data. Through a combination of lectures, software demonstrations, and practical exercises, learners will enhance their proficiency in interpreting seismic data for exploration and reservoir assessment.
