How does tubular extraction work?

Description:
 

Solution:
 Tubular extraction builds the trace by extracting samples from a time volume.
 The process involves converting the deviation survey from depth to time domain
 (using the sonic log) and then traveling down the borehole at the seismic
 volumes sample rate and extracting seismic data sample by sample. It uses
 bi-linear interpolation of neighboring traces if the borehole doesn't pass 
 through a given trace bin.
