Fast Amplitude Analysis from Geo-Model Horizons

In this paper, we propose a new workflow, based on a global approach in seismic interpretation, to better analyze seismic amplitudes in a new horizon framework. This method seeks to overcome limitations in seismic such as wavelet polarity changes and amplitude drops and allows for building a continuous geological model for detailed understanding of the different reservoir levels of the survey. The amplitude extraction on numerous horizons in a short vertical window enables the delineation of geological prospects and therefore minimizes risks for drilling decisions. In this paper, we will describe the proposed workflow, its background technology and some case studies where amplitude extractions on horizons computed from the geo-model enabled to identify unseen events with classical approaches and facilitated fast modeling for forward modeling.
