Abstract:

The Proterozoic (~1.43 Ga) Velkerri Formation (Beetaloo Basin, Northern Territory) hosts one of the world’s oldest petroleum systems, sourced and reservoir within organic-rich black shale deposited in a marine setting. A comprehensive characterisation of the Amungee Member of the Velkerri Formation was carried out to shed light on how the mineral and organic components in the Velkerri Formation are affected by post-depositional mechanical and chemical processes. This presentation will highlight the main diagenetic pathways identified via micro and nano-structural analysis, discuss their mechanisms in the context of Proterozoic oceans and biosphere and their effects on the bulk physical properties of the sediment.

Short bio:

Claudio Delle Piane is a Research Scientist at the Commonwealth Scientific and Industrial Research Organization (CSIRO). He is a geologist with background in structural geology and rock deformation; his research interests lie in the qualification and quantification of microstructure and its influence on the geomechanical, petrophysical and elastic properties of rocks.

His technical expertise is in the experimental evaluation of rock properties and microstructures by means of multiphysics laboratory measurements combined with analytical methods including optical and electron microscopy, X-ray and neutron diffraction and cathodoluminescence. These techniques have been used to gain better understanding of rock/fluid interactions, elastic anisotropy, stress/permeability evolution, frequency dependent seismic attenuation in rocks and fault reactivation.
