Dual-field seismic data are achieved recording particle velocity and pressure/stress at a same receiver-device location.

Abstract

Dual-field seismic data are achieved recording particle velocity and pressure/stress at a same receiver-device location. The dual-field method makes it possible to separate different components of the propagating wavefields activated by a single source. We analyze the results of an onshore seismic application using dual-field measurements in the shallow ground. We acquired the seismic data by reciprocal source-receiver geometry that makes it possible to limit the number of dual-receivers installations and to record dual-field data by a source activated along a seismic line. The analysis of data obtained by shallow stress sensors buried in the ground and surface geophone shows that the surface and body waves can be separated combining the dual signals without needing of multi-dimensional processing
