Reservoir Understanding and Prediction across sequences in Evaporite Geosystems


Join your trip experts, Dr. John Warren and Dr. Ian Dyson, on this 12 day field workshop and experience first hand the diversity and economic significance of saline systems and sequence analysis in Australia’s evaporite geosystems (modern and ancient). This 12-day combined field and lecture course captures the diversity and geological importance of textures in saline depositional systems across the world famous regions of the Coorong, Marion Lake, Lake Eyre, and the Flinders Ranges, as well as core-based study of facies textures, distribution and architecture. These field workshops are suitable for 10-15 participants.



• Understand the depositional and diagenetic significance of evaporite, limestone and dolomite textures across all scales (from core to reservoir)

• Learn to interpret mega-evaporite geometries in terms of tectonic and eustatic controls

• Better appreciate implications of saline stacking and halokinetic patterns in terms of reservoir and non-reservoir distribution, their architecture, the heterogeneity and quality of reservoir in an evaporite sequence framework.

• Integrate different scales of observation and interpretation from outcrop, to core, to wireline, to seismic scale.

• Development-  and production-scale modeling of facies distribution, stacking patterns, bed-scale stratigraphy, and the hierarchy of architectural elements within distributive saline depositional, halokinetic and diagenetic systems.
