Sonic Velocity/Variable Density
A sonic pulse is fired from a transmitter into the formation and the resulting returns are recorded as waveforms. These waveforms, represented in milliseconds, graphically depict the formation densities.
- SNC/VDL Sonic Velocity/Variable Density
- DT Delta Time
Used in correlation with other logs, the Sonic Velocity/Variable Density (SNC/VDL) tool is excellent for rock mechanics, location of regional water tables and detecting fractures. SNC/VDL surveys are logged in mud or water-filled open hole wells.
