PESA/ASEG WA April Young Professionals Speakers Night

Tuesday, 16 April, 2019 @ 5:30 pm - 7:00 pm

This Event is Proudly Sponsored by TGS:

PESA/ASEG WA invites you to their April Young Professionals Speaker Night. This is the perfect opportunity to socialise with your industry peers and enjoy two technical talks given by Claudia Valenti (Carnarvon Petroleum) and Alexander Costall (Curtin University).

Talk 1: Claudia Valenti (Carnarvon Petroleum)

Exploring the Triassic oil potential on the North West Shelf, Australia.


The exploration history of the North West Shelf suggests that the Australian petroleum systems are predominantly gas prone, typically found beneath the mid-Cretaceous regional seal.

Carnarvon Petroleum regional and local seismic mapping, in conjunction with exploration drilling results, indicates that the Triassic has three oil prone petroleum systems, the Early, Middle and Late Triassic.

Fundamental to understanding the areas where these three petroleum systems will work is a thorough understanding of palaeogeographies, palaeoenvironments and stratigraphy. Carnarvon believes the petroleum systems have a distinct palaeogeographic distribution and are not ubiquitous source rock/reservoir horizons across the North West Shelf.

Various laboratory analysis, sedimentology, seismic mapping, seismic facies work have contributed to the identification of the most encouraging areas to explore.

Additionally, the proximity of the Triassic geology of the North West Shelf to SE Asia Triassic geology, with their similar depositional setting, prior to Gondwana break-up, adds credence to the proposed theories. Examples of the early, middle and late Triassic oil petroleum systems will be illustrated and identified in some of the major basins on the NW Shelf.


Claudia Valenti obtained a Bachelor of Science in Geological Resources and a Master of Science. in Applied GeologicalSciences from the University of Pavia, Italy in 2012. She moved to Australia and started working for Carnarvon Petroleum as a geoscientist in 2014. For the last five years, her main focus has been interpreting the geology of the Browse, Roebuck Basin and Vulcan Sub-basin. Claudia is a member of PESA.

Talk 2: Alexander Costall (Curtin University)

Groundwater Throughflow and Seawater Intrusion in Perths’ Coastal Aquifers.


Some of the highest quality coastal groundwater reserves around the world are stored in extensive karstic aquifer systems. Excessive groundwater abstraction from these shallow coastal aquifers can cause seawater to move inland and degrade the quality of readily accessible water resources. With the changing climate already affecting groundwater recharge, and the world population continuing to expand, sustainable management of these aquifers is crucial to maintaining quality of life for millions of peoples worldwide.

Modern advances in geophysical exploration and imaging can provide highly detailed maps of subsurface properties. However, pitfalls remain. Electrical resistivity imaging (ERI) is one geophysical technique commonly used to image the seawater interface. Imaging outcomes from ERI can be easily misinterpreted. Forward models are often simple, and rarely is consideration given to the hydrogeological basis of the imaging outcomes. Simulation of seawater intrusion using numerical solute transport modelling has the potential to create forward models based on real fluid dynamics. These simulations can be converted to electrical forward models, allowing customised field campaigns to better identify the seawater interface and shallow hydrogeology.


Alexander is a PhD student at Curtin University, Department of Exploration Geophysics, specializing in near-surface hydro-geophysical problems. He completed a Bachelor of Science (Geophysics) with first-class honours in 2014 and works part-time within the geophysics department as a research assistant and laboratory demonstrator.

Alex’s research interests include groundwater and solute transport modelling, cooperative geophysical modelling, and exploration with ground penetrating radar and electrical resistivity.

Free: Please register for catering purposes.

This event is exclusively for Young Professionals (Young Professionals under the age of 35), so come along if you’re a student, graduate or working professional. Meeting your petroleum peers is a good chance to talk about your different background, experiences, projects and  companies with like-minded people in a very laid back and friendly setting.
