Patent ID: 8838392

Claim:
A method comprises: receiving, by a system having a processor, passive seismic data collected from measurements of seismic sensors in respective sensor assemblies, wherein the passive seismic data is based on multi-component measurements along two or more directions collected during periods when no active seismic source was activated; performing, by the system, attenuation of ground-roll noise in the passive seismic data using data from divergence sensors in at least some of the sensor assemblies, the data from the divergence sensors comprising measurements insensitive to a direction of wave propagation, wherein each of the divergence sensors includes a container containing a material and a pressure sensor immersed in the material, the divergence sensor and the seismic sensor of each of the at least some sensor assemblies are collocated, and the divergence sensors are buried below a ground surface and a portion of each of the at least some sensor assemblies including the respective divergence sensor is in contact with an earth medium underneath the ground surface; and outputting, by the system, the passive seismic data with the ground-roll noise attenuated to allow for performing an operation related to a subterranean structure using the passive seismic data with the ground-roll noise attenuated.
