..., it also detects the ground response through its baseplate, which is coupled with the ground surface. This ground response is recorded in the baseplate acceleration and can be used to analyze the underlying ground properties, for example ground stiffness and viscosity. Thus, a shallow shear wave velocity...

Wave velocities measured on room-dry core samples from a Lower Cretaceous carbonate reservoir under varying differential pressures up to 30 MPa are used to analyze the impact of grain/crystal size and pore types on velocity variation with pressure. The pore...
