Abstract

Structural interpretation can be challenging because of complex wave interactions and limited seismic bandwidth. A single seismic image can lead to multiple structural interpretations, reflecting structural interpretation uncertainties. Typically, this uncertainty is captured by generating several possible structural geometries. However, a quantitative assessment of the different possible structural interpretations is often difficult. In this paper we propose a methodology for assessing structural interpretations using seismic data misfit functions. We first develop a conceptual framework for solving such a problem before applying the method to a carefully designed synthetic study. Our results suggest that it is possible to appraise structural interpretation using seismic data if an appropriate misfit function is used.
