Geological sequestration of CO2 is considered to be an important greenhouse gas mitigation technology (Washington et al. 2009). Current public resistance to onshore sequestration sites makes offshore sites an attractive alternative. The Sleipner gas

Full waveform inversion is increasing being used in oil industry to quantify P and S-wave velocities of the sub-surface. So far, waveform inversion methods have been either 3D acoustic or 2D elastic. Furthermore, only low frequencies have been used b

OBC technology provides information on both pressure and 3 components particle velocity recorded at the seafloor level, allowing complementary PP and PS imaging. In the following paper, we describe a new elastic decomposition scheme in the tau-p doma

In prestack migration or imaging processing, estimation of a background velocity structure is a critical step. There are two main approaches to estimate seismic velocity using reflection traveltimes: one approach is traveltime tomography and the othe

Proceedings.
Usual tomography methods require ray tracing to numerically compote the traveltime in order to estimate, at each iteration of the inversion, the error between the data, i.e. the recorded times, and the computed times out of the current velocity model
