CREWES Blackfoot 3C-3D Seismic Dataset and CREWES research collection 2008

  • The well logs included in these releases are deviated wells. The LAS files only contain the top hole location. The bottom hole location can be found on page two of well_data.pdf. We do not have the well trajectories - so you will need to assume each trajectory was a straight line between the top and bottom hole positions in order to convert to true vertical depths.
