Determing first-break points in seismic data

A non-transitory computer-readable medium storing instructions which, when executed, cause a computer to perform operations comprising:

• selecting, by a hardware processor, potential first-break (PFB) points based on seismic data obtained by plurality of seismic receivers in a geological location;
• generating, by the hardware processor, a first plurality of first-break (FB) lines based on the PFB points;
• selecting, by the hardware processor, a first FB line among the plurality of FB lines;
• filtering, by the hardware processor, the PFB points based on the first FB line;
• generating, by the hardware processor, a second plurality of FB lines based on the filtered PFB points;
• selecting, by the hardware processor, a second FB line among the second plurality of FB lines;
• and
• determining, by the hardware processor, FB points based on the second FB line.

A device, comprising:

• at least one hardware processor;
• and
• a non-transitory computer-readable storage medium coupled to the at least one hardware processor and storing programming instructions for execution by the at least one hardware processor, wherein the programming instructions, when executed, cause the at least one hardware processor to perform operations comprising:
• selecting potential first-break (PFB) points based on seismic data obtained by plurality of seismic receivers in a geological location;
• generating a first plurality of first-break (FB) lines based on the PFB points;
• selecting a first FB line among the plurality of FB lines;
• filtering the PFB points based on the first FB line;
• generating a second plurality of FB lines based on the filtered PFB points;
• selecting a second FB line among the second plurality of FB lines;
• and
• determining FB points based on the second FB line.
