VELMOD

VELMOD is a seismic velocity modeling software designed to provide efficient processing and evaluation of seismic data, providing well-constrained velocity-depth models. The software utilizes tomographic techniques and forward modeling by kinematic and dynamic ray-tracing, making it an indispensable tool for seismic velocity modeling.

​

Input for VELMOD is Common Receiver or Common Shot Gathers recorded by stand-alone stations from wide aperture reflection refraction seismic observations (WARRS). The method involves:

• Deployment of stand-alone seismic stations distributed along a linear array or in a grid for 3D observations recording any type of energy source or earthquakes.

• Observation of the complete wave field from shallow to deep structures penetrating the crust and sedimentary basins, even in geological complex areas. Stations spacing can range from a few tenths of meters to one km or more, depending on the problem we intend to address 

• Inversion of the travel time data by tomographic techniques and subsequent modeling by ray-tracing permits the development of well constrained velocity depth models that can be further combined with other geophysical information, constraining the geological interpretation

• No need to mute recorded data but only enhance the seismic arrivals by simple processing methods. No static corrections needed since the topography is introduced in the modeling process as it is.
