Simultaneous shooting nodal acquisition seismic survey methods

A system to process blended seismic signals, comprising:

• a seismic sensor unit to record seismic signals generated by a plurality of seismic sources of a survey region, the seismic sensor unit including a geophone, a clock, a power source, memory, and an accelerometer;
• and
• one or more processors to:
• receive blended seismic signals detected by the seismic sensor unit;
• select a timing function that includes a ratio of a dither time to a shot interval used to perform a seismic survey that is less than or equal to ½;
• and
• deblend, based on the timing function, the blended seismic signals to generate data representing subsurface structures indicative of oil or gas.

A method to process blended seismic signals, comprising:

• providing a seismic sensor unit to record seismic signals generated by the plurality of seismic sources of a survey region, wherein the seismic sensor unit includes a geophone, a clock, a power source, memory, and an accelerometer;
• receiving, by one or more processors, blended seismic signals detected the seismic sensor unit;
• selecting, by the one or more processors, a timing function that includes a ratio of a dither time to a shot interval used to perform a seismic survey that is less than or equal to ½;
• and
• deblending, by the one or more processors, based on the timing function, the blended seismic signals to generate data representing subsurface structures indicative of oil or gas.
