In onshore fold and thrust belt geology, seismic wave propagation leads to complex waveforms due to large lateral variations in the earth parameters and multiple scattering effects. Moreover, due to acquisition difficulties in mountainous terrain, da

Nowadays, full-waveform inversion, based on fitting the measured surface data with modelled data, has become the preferred approach to recover detailed physical parameters from the subsurface. However, its application is computationally expensive for

In this paper we propose a strategy to estimate the impulse responses from a local target in the subsurface from surface seismic data, as an iterative sparse inversion approach in two steps. The first step is the process to estimate the upand downgoi

Imaging of steeply-dipping or overturned salt-flanks is still a challenge for the conventional migration techniques applied to surface seismic data. In the past, walkaway Vertical Seismic Profiling (VSP) data has proven to add value in mapping or ima

One of the values of VSP (Vertical Seismic Profiling) data is its potential to provide high-resolution details for the reservoir area. However, VSP imaging is challenging because of the poor illumination from the primary-only data. In the past, some
