.... The combined DPW dataset approximates the DPW dataset transformed from split-spread shot gathers. We also show that utilizing the reciprocity principle can increase the DPW migration efficiency. Introduction Plane wave migration techniques have been introduced (Liu et al., 2006; Liu et al., 2002; Stoffa...

... on the In Salah sequestration site, we compute the field characteristics of the modeled field just once for all potential source points using the reciprocity principle. The resulting inversion is straightforward and allows estimation of the spatial uncertainty as a function of the noise in the data. At far...
