Abstract
Systems and methods for wireless data acquisition in seismic monitoring systems are disclosed. The method includes obtaining a signal table for an emitted seismic signal, receiving seismic signal data from a receiver configured to transform seismic signals into seismic signal data, and storing the seismic signal data on a storage system. The method also includes determining a time span for the seismic signal data and generating a reduced data set based on the seismic signal data, the signal table, and the time span.

A method for seismic data acquisition performed by a collection node during a seismic survey of a subsurface geological formation, the method comprising:
- obtaining a signal table for an emitted seismic signal;
- receiving seismic signal data from a receiver configured to transform seismic signals emerging from the subsurface geological structure into seismic signal data;
- storing the seismic signal data on a storage system;
- determining a time span for the seismic signal data;
- and
- generating a reduced data set based on the seismic signal data, the signal table, and the time span, wherein the generating includes:
- generating frequency-domain data by applying a Fourier transformation to the seismic signal data;
- determining an emitted frequency based on the signal table and the time span;
- and
- selecting an amplitude and phase from the frequency-domain data, the amplitude and phase corresponding to the emitted frequency.
