Abstract
A method for seismic exploration of a subsurface formation with a seismic survey system includes directly receiving a message, at a first fleet of seismic sources, from a second fleet; storing the message at the first fleet; verifying one or more constraints related to the first and second fleets, at the first fleet; initiating a triggering sequence of the seismic sources of the first fleet, upon verification of the one or more constraints, with no input from a central unit of the seismic survey system; and performing a sweep based on the triggering sequence.

A method for seismic exploration of a subsurface formation with a seismic survey system, the method comprising:
- directly receiving a message, at a first fleet of seismic sources, from a second fleet;
- storing the message at the first fleet;
- verifying one or more constraints related to the first and second fleets, at the first fleet;
- initiating a triggering sequence of the seismic sources of the first fleet, upon verification of the one or more constraints, with no input from a central unit of the seismic survey system;
- and
- performing a sweep based on the triggering sequence.
An electronic part that controls a sweep of a first fleet of seismic sources, the electronic part comprising:
- a local controller that is part of the first fleet of seismic sources, and the local controller is configured to directly receive a message from a second fleet;
- and
- a memory configured to store the message,
- wherein the local controller is further configured to,
- verify one or more constraints related to the first and second fleets,
- initiate a triggering sequence of the seismic sources of the first fleet, upon verification of the one or more constraints, with no input from a central unit of a seismic survey system that includes the first and second fleets;
- and
- determine the seismic sources of the first fleet to perform the sweep based on the triggering sequence.
A non-transitory computer readable medium including computer executable instructions, wherein the instructions, when executed by a computer, implement a method for emitting seismic waves, the medium comprising instructions for:
- directly receiving a message, at a first fleet of seismic sources, from a second fleet;
- storing the message at the first fleet;
- verifying one or more constraints related to the first and second fleets, at the first fleet;
- initiating a triggering sequence of the seismic sources of the first fleet, upon verification of the one or more constraints, with no input from a central unit of the seismic survey system;
- and
- performing a sweep based on the triggering sequence.
