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.

New tools for old rocks: first cycle provenance information. The aims of this research are to enhance stratigraphic understanding of sedimentary sequences in Western Australia through application of novel provenance fingerprinting tools in K-feldspar (Pb isotopes) & apatite (U-Pb, Sr isotopes and grain chemistry). While much stratigraphic characterization has been based on detrital zircon ages & their correlation to basement sources, two major limitations are apparent: a) zircon may be multicycl ....New tools for old rocks: first cycle provenance information. The aims of this research are to enhance stratigraphic understanding of sedimentary sequences in Western Australia through application of novel provenance fingerprinting tools in K-feldspar (Pb isotopes) & apatite (U-Pb, Sr isotopes and grain chemistry). While much stratigraphic characterization has been based on detrital zircon ages & their correlation to basement sources, two major limitations are apparent: a) zircon may be multicycle, blurring source-sink relationships, b) zircon may be absent in mafic lithologies thus biasing investigations. In this work K-feldspar & apatite provenance investigation will be undertaken on a state wide basis and include case studies in the Yilgarn Craton and Canning & Northern Carnarvon Basins.
