Overburden seismic anisotropy is an active topic as it can distort the seismic response of deep targets. In order to characterize shallow unconsolidated marine clay, a 9C walkaway VSP was conducted in the shale gas area of the St-Lawrence Lowlands, near Montreal, Québec. Assuming transverse isotropy, Thomsen parameters were estimated and used as inputs in a synthetic model. Similarities between synthetic and real data tend to confirm the VTI symmetry hypothesis although some behavior remains unexplained by the model.
