Welcome to the Lake Eyre Basin Analogues Research Group

Recognition of dryland fluvial, aeolian and lacustrine deposits has significant implications for reducing the risk of predicting reservoir and seal connectivity, and hence potential productivity. Studies of modern analogues, such as those within the Lake Eyre Basin, can substantially contribute to understanding depositional processes and their influence on reservoir geometry and quality in dryland settings.

Studies of preserved sediments within modern sedimentary basins are essential for understanding the three-dimensional stratigraphic record of ancient deposits - the ultimate result of the subtle balance between changes in accommodation rates and sediment supply. Our research findings will significantly impact exploration and development efforts in some of the frontier areas and facilitate improved production from existing basins around the world (e.g. Triassic of the North Sea and Algeria, Pliocene of the South Caspian Sea, Permian of the Arabian Peninsula, Lake Chad).

LEBARG History
The LEBARG Consortium is currently in Phase III, with eight industry members located around the world. Previous research phases focused on investigating the Neales Terminal Splay (Lake Eyre) as an accessible delta analogue (Phase I), and establishing the Lake Eyre region as a reservoir analogue for dryland rivers and terminal splays, using field sites along the western side of Lake Eyre North (Phase II). Research methods included extensive coring, trenching, augering and mapping of facies, architectures and geometries of sedimentary deposits at varying scales. The present phase, Phase III, involves field work on both the western and eastern shores of Lake Eyre North, including at two previously unstudied localities. Phase III aims to expand upon and test the Terminal Splay Facies Model developed in Phase II, apply these results to reservoir modelling, focus on issues of preservation and correlation, and extend the analogues investigated to include the sedimentary mini-basins of the Channel Country rivers.
