Systems and methods for generating synthetic seismic attributes from well logs

A method for generating a synthetic seismic attribute from a well log, the method comprising:

• (a) receiving well log data obtained from a subsurface region;
• (b) determining a plurality of traveltimes of different seismic signals observed at irregular intervals of time from the well log data;
• (c) determining, based on the well log data and traveltimes, a plurality of reflection coefficients;
• (d) convolving the plurality of reflection coefficients with a source wavelet to generate a plurality of convolved source wavelets at the irregular intervals of time;
• (e) transforming the plurality of convolved source wavelets at the irregular intervals of time into a plurality of synthetic values located at regular intervals of time;
• and
• (f) generating, based on the plurality of synthetic values, synthetic data associated with the subsurface region.

A system comprising:

• one or more processors;
• and
• a storage device coupled to the one or more processors, the storage device configured to store instructions that, when executed by the one or more processors, configure the one or more processors to:
• receive well log data obtained from a subsurface region;
• determine, based on the well log data, a plurality of traveltimes of different rock properties observed at irregular intervals of time;
• determine, based on the well log data and the plurality of traveltimes, a plurality of reflection coefficients at the irregular intervals of time;
• convolve the plurality of reflection coefficients with a source wavelet to generate a plurality of convolved source wavelets;
• and
• generate a synthetic seismic attribute associated with the subsurface region using the plurality of convolved source wavelets.
