The seismic data processing and interpretation as migration transformations and modeling can be realized in finite-difference continuation of a time field. That is reached by a direct solution of an eikonal equation. Theoretical bases and algorithms of three-dimensional finite-difference direct and reverse continuation of the time field are given in the article. Originality of the offered method consists of a strict quadratic approximation of the differential eikonal equation by a finite-difference method with the use of special grids. Application efficiency of a time field continuation in three-dimensional heterogeneous environment is shown on modeling and real materials.

Keywords: finite-difference continuation of a time field, migration, modeling, eikonal equation.
