Latest Jurassic history of the Exmouth Sub-basin, North West Shelf: lowstand deposits of the basal Barrow Group. Sand-filled canyons may be excellent petroleum reservoirs, however, interpretation of formation and sediment filling of these major deep marine features is controversial.

Sand-filled canyons may be excellent petroleum reservoirs, however, interpretation of formation and sediment filling of these major deep marine features is controversial. This project seeks to elucidate the origin of canyons and associated basin floor fans by combining sedimentological data with seismic interpretation and modelling to generate new insights into the history of the Exmouth Sub-basin during the Latest Jurassic. In particular, this project provides an opportunity to explore the role of tectonism in canyon formation, the results of which will be of international interest. Geological models developed in this project will enhance our understanding of deep marine systems.Read moreRead less
Seismic velocity problems associated with Cretaceous-Tertiary carbonate sediments that overlie oil and gas fields of the North West Shelf. The major aim of this collaborative study between Partner Oil Companies and The University of Melbourne is to understand seismic velocity problems associated with tropical carbonate sediments on Australias? North West Shelf. These problems can hinder the hydrocarbon exploration efforts below these carbonates. The project is a multi faceted study and will invo ....Seismic velocity problems associated with Cretaceous-Tertiary carbonate sediments that overlie oil and gas fields of the North West Shelf. The major aim of this collaborative study between Partner Oil Companies and The University of Melbourne is to understand seismic velocity problems associated with tropical carbonate sediments on Australias? North West Shelf. These problems can hinder the hydrocarbon exploration efforts below these carbonates. The project is a multi faceted study and will involve integration of seismic stratigraphy with sedimentological, micropaleontological, and geophysical data. The methods outlined below would underpin any seismic depth migration applications, thereby assisting with the delineation of new gas and oil fields, and help with the estimation of reserves in existing fields.

The use of outcrop analogues to characterise large-scale deepwater sedimentary architecture. Deepwater turbidite sedimentary systems are one of the modern frontiers in petroleum exploration, with many major discoveries expected from around the world in the next 25 years. Technological advances in the drilling and production of the deepwater hydrocarbons now enable the exploration and exploitation in this realm. However, the geometry, internal architecture and spatial variations of deepwater sand ....The use of outcrop analogues to characterise large-scale deepwater sedimentary architecture. Deepwater turbidite sedimentary systems are one of the modern frontiers in petroleum exploration, with many major discoveries expected from around the world in the next 25 years. Technological advances in the drilling and production of the deepwater hydrocarbons now enable the exploration and exploitation in this realm. However, the geometry, internal architecture and spatial variations of deepwater sandbodies are still poorly understood. By using state-of-the-art outcrop, modern submarine fan and petroleum exploration data, this research project will improve the understanding of the reservoir geometry and internal architecture of deepwater sandbodies. The results will aid in the exploration and development of hydrocarbons in deepwater sedimentary systems.Read moreRead less
Longshore Sediment Supply to the Deep Ocean. The current model to supply sand to deep water off continental margins is that provided by rivers operating at low sea level. We propose an alternative model in which sand is provided by longshore transport to deep water at high sea level north of Fraser Island, SE Queensland. Here we will test the validity of our new model by site studies of sea bottom morphology, composition and dynamics. If the model proves true, we will have: 1) generated an entir ....Longshore Sediment Supply to the Deep Ocean. The current model to supply sand to deep water off continental margins is that provided by rivers operating at low sea level. We propose an alternative model in which sand is provided by longshore transport to deep water at high sea level north of Fraser Island, SE Queensland. Here we will test the validity of our new model by site studies of sea bottom morphology, composition and dynamics. If the model proves true, we will have: 1) generated an entirely new exploration model for deepwater hydrocarbons, 2) provided new expertise and seabed maps for generating a superior marine naval defence capability.Read moreRead less
Reconstruction of marine ecosystems following the greatest mass extinction during the Phanerozoic history of Earth life: Lessons for the present. Frequent defaunation events strongly threaten sustainable development of marine resources and human environments especially in countries that are surrounded by oceans such as Australia. By analysing recovery mechanisms of marine ecosystems following the Permian-Triassic mass extinction, the greatest crisis of Earth life, we will develop predictive tool ....Reconstruction of marine ecosystems following the greatest mass extinction during the Phanerozoic history of Earth life: Lessons for the present. Frequent defaunation events strongly threaten sustainable development of marine resources and human environments especially in countries that are surrounded by oceans such as Australia. By analysing recovery mechanisms of marine ecosystems following the Permian-Triassic mass extinction, the greatest crisis of Earth life, we will develop predictive tools for analysing restoration of modern marine defaunated ecosystems. Understanding biotic extinction and recovery is crucial to understanding the evolution of the Earth's biosphere. This study increases Australia's research profile on this global issue. The target strata are quality oil source rocks in Perth Basin, and thus this project is beneficial to the Australian petroleum industry.Read moreRead less
