refraction seismics



the different modules for refraction seismics




Reflexw is designed for the complete processing and interpretation of

2-dimensional seismic refraction data


The program supports all well known seismic dataformats. The full 2D-processing of the shot data starting from setting the geometry, filtering the shot data up to picking the first arrivals is given. Different methods for the interpretation of the picked traveltime data are available. For a detailed look please follow the links within the text.

The 2D seismic shot data are processed within the 2D data-analysis module which includes various possibilities of setting the geometries and also all necessary filter and edit functions. Any kind of line based geoemetry for the shots and the receivers is possible. Some interactive interpretation tools like the interecepttime method are included for a very quick interpretation even within the field.

Different kinds of picking the first arrivals are included. You have the choice between manual picking, continuous picking and a semi-automatic picking using a phase follower (manual editing is always possible).

The picked traveltime data are interpreted within the modelling (traveltime inversion) module. The first part (traveltime processing) contains the possibility to put together the picked traveltimes from several shots and to assign the picks to special layers. There exist nearly no practical limitation for the number of shots and receivers.


The second part (traveltime interpretation) contains the interpretation tools like 2D wavefront-inversion, 2D forward raytracing,  interactive 1-dimensional adaptation and 2D refraction tomography. All interpretation tools work together,e.g. the tomographic or wavefront result may be easily controlled by the forward raytracing. The 2D-interpretation tools are based on a FD-approximation of the eikonal equation whereby complex model structures are well modelled.
