Abstract
The invention pertains to a method for enhancing the determination, from a seismic image of at least a portion of a seismic horizon in a three-dimensional domain. The method comprises: receiving the seismic image; receiving a plurality of related control points; defining pseudo-rectangles; for each pseudo-rectangle applying a diffeomorphic transformation F: defining a new domain; transforming points of the seismic image; transforming said pseudo-rectangle into a corresponding rectangle; applying a horizon reconstruction algorithm to the transformed points, to determine a part of a transformed horizon, the reconstruction comprising solving a Poisson equation; and computing a part of the horizon, said computing comprising applying an inverse diffeomorphic transformation F−1 to the determined part of a transformed horizon.
