Seismic waveform classification: renewing the interest in Barrolka field, SW Queensland, Cooper Basin

Abstract

Seismic wave form classification techniques have been used to significantly improve the efficiency of the interpretation of the Barrolka field 3D seismic survey. Pattern recognition of seismic shape based on a neutral network has proven to be powerful approach in reducing risk associated with characterising and predicting the extent of the Barrolka field's historically elusive PC30 reservoir. This technique resulted in recent drilling success with development wells intersecting predicted reservoir and resulting in exceptional initial gas rates, a contrast to the field complex's 30 years low drilling success. This study has rejuvenated interest to convert the field's large contingent resource to reserves.
