Guest Speaker(s): Dr Fiona Burns (Task Fronterra)

Fiona Burns joined Task Fronterra at the start of 2024 as a Senior Sedimentologist/Ichnologist. She has over 25 years’ experience in the Oil and Gas industry with expertise in the ichnofabric analysis, and the application of trace-fossil analysis to depositional modelling and high-resolution sequence stratigraphy. Prior to this she collaborated on various subsurface projects worldwide through her company  Firmground, including UK North Sea, offshore West Africa, offshore China, offshore Thailand, Papua New Guinea and NZ. Here in Australia, she has worked extensively on single and multi-well studies in the Bonaparte, Browse, Carnarvon and Perth Basins, including depositional modelling for use in CCUS studies. Fiona also runs core workshops on Ichnology and fieldtrips in NZ. Fiona was a postdoctoral Research Fellow at the University of Western Australia (2001-2004) and a Senior Research Fellow at Curtin University from 2004-2007 (positions sponsored by a consortium of oil companies and MERIWA) where she also taught Sedimentology and Petroleum Geology. She holds a B.Sc. from Imperial College an M.Sc. from Aberdeen University and a Ph.D. from Manchester University. Fiona is an Associate Editor of Ichnos, a journal which aims to promote excellence in ichnologic research.

Fiona is the PESA WA branch president.

New Insights into Depositional Modelling of the Permian Kingia Sandstone in the Perth Basin Using Ichnology

Presented by Dr Fiona Burns (Task Fronterra)

Abstract

Historically, sedimentological interpretations of the Kingia Sandstone in the northern Perth Basin have relied heavily upon conventional sedimentary facies analysis of a limited dataset integrating core with well-log data. This paper however provides invaluable insights into the high-resolution depositional modelling of the Kingia Sandstone using sedimentary facies analysis integrated with detailed ichnological studies. Historic cored wells have also been re-evaluated utilising an ichnological approach, while newly released cored wells have been interpreted, also using this integrated approach. Cores from a variety of wells including but not limited to West Erreguella-4, South Erreguella-1, Mountain Bridge-1, Corybas-1, Waitsia-1, Waitsia-2 and Waitsia-3 have been included in this study.

The results allow the subdivision of the Kinga Sandstone into numerous sub-environments reflecting marginal to fully marine  sub-environments. The Kinga sandstone is interpreted to represent deposition in a wave-dominated deltaic system, with trace-fossil assemblages key to the evaluation of stress levels (e.g. freshwater dilution) in the system. Local sharp-based shoreface packages, abruptly overlying shelfal deposits, are interpreted to represent forced regressive events during overall highstand progradation of the Kingia shoreface system.
