Depth Conversion

 Syntillica can provide expertise not only in interpretation and mapping in a geologically-consistent manner but also testing of different velocity models by depth conversion.

Seismic reflection data records the two-way travel time to a reflection event or horizon from the surface. Depth conversion is the process by which interpreted seismic horizons and faults (and time domain seismic itself) are converted from the travel time domain to the depth domain. (in contrast depth migration is an imaging technique that improves reflector positioning). 

Depth migrated data is often converted back and forth between time and depth domains to test alternative velocity models.  This can be especially important in high velocity carbonate overburden sequences where a slight error in interval velocity can have a significant impact on in-place volumes of underlying reservoir layers.
