TwoShots is a 2D seismic refraction imaging software package designed for geophysical engineering applications.  It requires only two shots, the forward shot and the reverse shot, to image bedrock topography.  The program applies the wavefront reconstruction theory (migration) to backward propagate two traveltime curves.  The velocity field for the propagation is automatically derived from the near-offset traveltimes.  In the subsurface, any point at which the sum of the traveltime fields equals to the the reciprocal time should be an image point.

Designed in the same fashion with GeoCT-I, TwoShots opens up a window with three sub windows for picking traveltimes, QC traveltimes, and displaying a velocity image.

TwoShots is designed for Windows only.  For any evaluation request, please contact: support@geotomo.com
