Abstract
This paper presents a method for restoring missing seismic traces by using the two-dimensional dip moveout (DMO) equation. A fundamentally new formulation of the initial-boundary-value problem based on the Goursat problem is proposed. A modified finite element method is used for numerical solution. The method is tested on model examples and actual seismic data.
