On: 'An integrated surface and borehole seismic case study: Fort St. John Graben area, Alberta, Canada,' by R. C. Hinds, R. Kuzminski, N. L. Anderson, and B. R. Richards (November 1993 G<scp>EOPHYSICS</scp>, 58, p. 1662–1675)

However, a question of principle arises. What is an integrated interpretation?
