Appraising structural models using seismic data: problem and challenges

Abstract

Structural interpretation plays an essential role in geological model building and, as a consequence, on numerical simulations and predictions that follow. However structural interpretation can be highly subjective; a single seismic image will most often allow multiple geologically probable interpretations. In this paper, we assume we have a sampler providing multiple structural interpretations reflecting geological knowledge. We focus on the problem of appraising these models, i.e. determining which structural interpretations are more likely than others. For this, we propose to use seismic data; both vertical seismic profiling (VSP) and seismic reflection configurations are considered. We propose several ways to generate a velocity model consistent with migration velocity and with a particular structural interpretation. Last, we highlight the promises and then we discuss about the challenges of the proposed method.
