Tracing seismic sections to convert to digital format

摘要

Method, system, and computer program product for tracing seismic sections to convert to digital format are provided. The method includes: receiving a scan of a seismic section having multiple overlapping traces measured at spot points; splitting the traces into segments; associating the segments with appropriate baselines; estimating the traces between segments using logical rules; and deriving amplitudes of the traces.

1. A method for converting tracing paper data to digital format, comprising:
providing said tracing paper having a plurality of oscillating traces with a plurality of overlap areas between said plurality of traces; scanning said tracing paper and converting said tracing paper to a binary digital image; identifying said plurality of overlap areas by processing said binary digital image; physically splitting said plurality of traces into a plurality of non-touching segments by processing said binary digital image; reconstructing said plurality of traces by independently processing said non-touching segments of said binary digital image to restore values of said plurality of traces in said plurality of overlap areas; and outputting data of each of said plurality of traces as a data structure.
