1. A computer-implemented method for transforming a seismic data volume acquired in a seismic survey to a corresponding data volume which, when visually displayed, shows a representation of subterranean reflector surfaces that gave rise to the data by reflecting seismic waves, said method comprising:

  • (a) picking seismic reflections from the data volume, and creating initial surfaces from the picks;

    (b) breaking surfaces into smaller parts (“

    patches”

    ) that are predominantly topologically consistent;

    (c) merging neighboring patches in a topologically consistent way, thus extracting topologically consistent reflection-based surfaces from the seismic data volume; and

    (d) displaying the extracted surfaces for visual inspection or interpretation, or saving their digital representations to computer memory or data storage.
