Sealing Potential of Shale Sequences through Seismic Anisotropy Analysis

Abstract

This study investigates the potential relation of seismic anisotropy measured by surface seismic and the sealing potential of the shale sequences. Two case studies analyzed such a relationship. The Gippsland basin and Exmouth sub-basin are both hosts to prolific hydrocarbon resources and offer plenty of seismic data and sealing potential measurements. Weak anisotropy parameters extracted from carefully reprocessed seismic data show in both cases a positive correlation between sealing capacity and anisotropy of the shale.
