Abstract
Systems and methods perform consistent dip estimation for seismic imaging. An example system applies global consistency constraints during iterative volume dip estimation of a seismic volume to improve upon conventional dip estimation methods. With each iteration, the system applies single and joint dip constraints, checking local dip estimates for reciprocity, causality, consistency, and vertical and lateral continuity. At discontinuities in the seismic volume, local divergences are marked with a quality attribute. Upon convergence of the volume dip estimation, the volume may be rendered in 3D, including the discontinuities. In performing volume dip estimation, the system can also provide automatic horizon interpretation and automatic fault detection.
