Webinar description
Surface waves (groundroll) recorded in the seismic data, can be a valuable tool in mineral exploration. Their sensitivity to the near-surface properties allows the estimation of high-resolution shallow VS and VP models and the computation of accurate static corrections, which can improve the imaging of the mineralization targets. In addition, the longer surface-wave wavelengths caused by the high seismic velocities of typical mineral exploration sites, can be useful to indicate the top of the mineralization, particularly in passive seismic surveys, where lower surface-wave frequencies can be measured.
In this webinar, we propose methods which allow the effective use of surface waves in the challenging and noisy environments of mineral exploration. The methods are applicable on 2D and 3D schemes, active- and passive-source seismic data, and are highly automated and computationally efficient, suitable for large-scale applications.
Their successful application on legacy and newly acquired data in the framework of Smart Exploration project shows the value of the recorded groundroll in mineral exploration.
