Service: Velocity or Checkshot Survey
Travel-time measurements are
acquired with receivers placed at known depths in a well.
These measurements produce accurate time-depth and seismic
velocity results that can be used to calibrate well log
data. Velocity survey information is presented as
time-depth correlation plots and detailed velocity tables.
Borehole seismic-generated velocity information is used to
calibrate acoustic well log data and produce accurate
synthetic seismograms. |

|
Synthetic seismograms link surface seismic
time-domain information with high-resolution,
depth-domain well log data.
