Seismic data conversion (stretching) from Time domain to Depth domain.

Theory

The seismic data conversion module from time domain to depth domain is used to transform seismic time data (such as arrival times of seismic waves) into depth-related data corresponding to the Earth's subsurface layers. This process is essential for accurate modeling and analysis of geological structures, such as oil and gas reservoirs, and for conducting seismic exploration. The module works based on two input datasets: interval velocity data for each layer and the seismic time data. The conversion is performed by integrating the interval velocity with the time data, using a velocity-depth relationship, to translate the measured time into the corresponding depth.

Input data

 Input time gather - input seismic data set in time domain.

 Input velocity - interval velocity model.

Parameters

 V0

replacement velocity m/s.

Settings

 Number of threads

limit number of threads on main machine.

 Skip - switch-off this module (do not use in the workflow).

Output data

  Output depth gather - output gather in depth domain.

Examples

 Workflow for time to depth conversion. There are two input data sets: seismic stack and interval velocity that are connected to the Stretching time to depth module:
