Inversions of seismic surveys often give quite low-resolution results that are difficult to compare with well data and geological models. We are therefore developing a multi-vintage seismic inversion based on a Petro-Elastic Model (PEM), called PetroSI-4D. This involves input from the geological model and good control on the petrophysical correlation between porosity and PEM-based seismic velocities. All vintages and input angle stacks are combined to jointly invert for layer thickness, rockdoi:10.3997/2214-4609.20147814 fatcat:fizbz2dnsjg3vom5venwcntm2u
