Abstract

Simultaneous Joint Migration and Inversion (SJMI) is an effective time-lapse tool for reservoir monitoring, which combines a joint time-lapse data processing strategy with the Joint Migration Inversion (JMI) method. In SJMI, fine details are not expected in its inverted velocity model, as it only explains the propagation effects in the data, while the scattering effects are explained by the inverted reflectivity model. However, for time-lapse processing, high-resolution time-lapse velocity differences are usually a demand. Therefore, we propose to make a link between reflectivity and velocity update during SJMI optimization, in order to get more localized time-lapse velocity differences. In the end, with a highly realistic synthetic model based on Grane field offshore Norway, we demonstrate a more localized inverted time-lapse velocity difference using the proposed SJMI, compared with the regular SJMI.
