A Novel Workflow to Model Geomechanical Properties Using Fracture Coherence Interpretation and Density Inversion in the Rangal Coal Measures of the Bowen Basin in Australia
Abstract:The study focused on the Permian aged Rangal coal measures within a 3D seismic volume in middle of Bowen basin. The Rangal Coal Measures (RCM) are a middle-rank coal seam gas (CSG) target with low permeability. Approximately 150 to 200 wells, with geophysical log data, are unevenly distributed in the seismic area of 51 km2. The effect of stress and related geomechanics on producing wells has been poorly understood. Petrophysical data, 3D seismic cube, geographic information system (GIS), borehole imager and we… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
