Integrated Sequence Stratigraphy to Improve Technically Recoverable Resources Estimation and Flow Modelling

This research succesfully defined a skeleton for a chronostratigraphic framework, setting the stage of an extended project.

The connectivity of coal beds is an important consideration for the economics and feasibility of coal seam gas production.  The areal extent of coal is related to the environment of deposition and factors affecting preservation.  It is critical to understand the cyclicity within the succession and the lateral shifts in coal forming environments over time

The exploratory phase of the Seismo-Stratigraphic Interpretation pilot project successfully defined a skeleton for a chronostratigraphic framework. The results show differences with previous (pragmatic) approaches of defining Surat Basin stratigraphy. The present framework requires further testing and integration with other types of data for validation. Furthermore, the impacts of this first principles approach on coal seam gas reservoirs and aquifers of the Great Artesian Basin need to be investigated and understood. This has set the stage for an extended project to incorporate detailed facies analysis from core, extended seismic facies analysis, and additional chronometric dating from areas determined important to the stratigraphic framework.

The impact of the new correlation scheme based on geological processes will be evaluated by static and dynamic modelling.
