Generating seismic surfaces

A method for seismic surface generation, the method comprising:

• preprocessing a seismic volume to reduce processing, resulting in a preprocessed seismic volume, the preprocessing including cropping the seismic volume, masking the seismic volume, and resampling the seismic volume;
• identifying areas of high signal-to-noise ratio in the preprocessed seismic volume;
• masking the preprocessed seismic volume based on the signal-to-noise ratio;
• and
• using a patch to train a neural network to generate a seismic surface.

A system, comprising:

• processor and memory, the memory including instructions that cause the processor to:
• crop a seismic volume within a cropping range of a wellbore trajectory to generate a cropped seismic volume;
• resample the cropped seismic volume to a predetermined sampling frequency to generate a resampled seismic volume;
• mask the resampled seismic volume within a masking range of the wellbore trajectory resulting in a masked seismic volume;
• extract patches from the masked seismic volume based on a signal-to-noise ratio of the masked seismic volume;
• and
• generate a seismic surface using the patches.
