Spatially adaptive vibrator sweep parameter selection during seismic data acquisition

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• emitting, from a vibratory seismic source into geological layers, a frequency sweep using sweep parameters, wherein the sweep parameters include frequencies and modulation parameters for seismic waves;
• receiving, from one or more sensors, signals including seismic data acquisition information, including values identifying energy reflected back from boundaries where rock properties change;
• determining and updating, based on the reflected seismic values that are attenuated, optimum sweep parameters to compensate for local geology effects;
• and
• repeating the emitting, receiving, determining attenuation, determining optimum sweep parameters, and updating until the received signals, when displayed to on-site personnel with a percentage of change in signals between successive sweeps, are accepted by the on-site personnel.

A computer-implemented system, comprising:

• one or more processors;
• and
• a non-transitory computer-readable storage medium coupled to the one or more processors and storing programming instructions for execution by the one or more processors, the programming instructions instruct the one or more processors to perform operations comprising:
• emitting, from a vibratory seismic source into geological layers, a frequency sweep using sweep parameters, wherein the sweep parameters include frequencies and modulation parameters for seismic waves;
• receiving, from one or more sensors, signals including seismic data acquisition information, including values identifying energy reflected back from boundaries where rock properties change;
• determining which of the reflected seismic waves are attenuated using an integral transform and a thresholding algorithm for image segmentation;
• determining and updating, based on the reflected seismic values that are attenuated, optimum sweep parameters to compensate for local geology effects;
• and
• repeating the emitting, receiving, determining attenuation, determining optimum sweep parameters, and updating until the received signals, when displayed to on-site personnel with a percentage of change in signals between successive sweeps, are accepted by the on-site personnel.
