The Modern Carbonate Depositional Environments course on Heron Island is aimed at geologists and reservoir engineers, and will include hands-on assessments of key features of modern carbonate systems which are pertinent to reservoir including facies, geometry and scale, and thus related issues of interconnectedness, flow units, flow barriers, and heterogeneity. The focus of this field course is providing participants with a practical understanding of the sedimentary characteristics and geometries of the principal reefal facies and the physiographic controls on their distribution. Field observations will be supported by discussion relating potential reservoir quality and porosity modification to depositional setting.
