Wave velocity determination for seismic imaging

A system comprising:

• at least one processor;
• and
• a memory communicatively coupled to the at least one processor, the memory storing instructions that when executed cause the at least one processor to perform operations comprising:
• receiving sensor data generated by one or more sensors through seismic probing of an underground environment, the sensor data including pressure (P) wave data;
• determining pressure-shear (PS) wave data present in the sensor data, wherein a PS wave includes a P wave as an incident wave and a shear (S) wave as a reflected wave;
• generating a common focus point (CFP) ratio spectrum based on a ratio of P wave velocity to S wave velocity;
• determining an optimal ratio curve through at least a portion of the CFP ratio spectrum;
• generating, by the at least one processor, one or more images of the underground environment by scanning along the optimal ratio curve;
• and
• providing the one or more images for presentation through an interface.

One or more non-transitory computer-readable storage media storing instructions which, when executed by at least one processor, cause the at least one processor to perform operations comprising:

• receiving sensor data generated by one or more sensors through seismic probing of an underground environment, the sensor data including pressure (P) wave data;
• determining pressure-shear (PS) wave data present in the sensor data, wherein a PS wave includes a P wave as an incident wave and a shear (S) wave as a reflected wave;
• generating a common focus point (CFP) ratio spectrum based on a ratio of P wave velocity to S wave velocity;
• determining an optimal ratio curve through at least a portion of the CFP ratio spectrum;
• generating, by the at least one processor, one or more images of the underground environment by scanning along the optimal ratio curve;
• and
• providing the one or more images for presentation through an interface.
