3D Depth Velocity Model Building and Depth Imaging using Aspen GeoDepth

This course is designed to introduce new and existing users to the working environment and applications in GeoDepth. The course guides the student through our recommended basic time-to-depth velocity
analysis workflows and time-to-depth migrations in GeoDepth 3D. It offers students two alternatives for building the initial model: a structure-independent (grid-based) and a layer-based model building
workflow. The training manual offers a detailed step-by-step description of each workflow, including operational information about each application, as well as theoretical considerations and practical hints
regarding each step. The training manual maintains a realistic production-oriented approach, and emphasizes correct practices (e.g., correct setup, QC of results after each stage, etc.). Additional
example workflows are also provided.

Audience:

New GeoDepth users, geophysicists
