Velocity Modeling & Depth Conversion

Description: 

Depth conversion is a basic skill for seismic interpreters. However, there is no single methodology that is optimal for all cases since the available seismic and geologic control varies in quantity and quality within each project. This course helps interpreters to have a good understanding of the velocity types, chose the adequate method for velocity modeling, and make a depth-error analysis.
