PESA QLD: Technical Luncheon, 22nd October– Mr Pascal Asmussen

Thursday, 22 October, 2020 @ 12:15 pm - 2:00 pm (Australia/Brisbane time)

Free – $95.00

Guest Speaker(s): Mr Pascal Asmussen & Mr Victor M Sepulveda

Pascal recently graduated from the School of Earth and Atmospheric Science from QUT with a PhD in Earth Science. He currently holds a position as Postdoctoral Research Fellow at the Sustainable Minerals Institute and works on integrating Spatial Science approaches and methodologies into mine site rehabilitation projects across Queensland. His research interests are in geochronology, chemostratigraphy, tectonics of sedimentary basins and geostatistics.

Victor is a Geologist with 12 years of experience in both the Energy and Mining industry sectors. His recent Experience was with the Ministry of Mines and the National Hydrocarbons Agency (ANH) in Colombia as a Manager of geological and geophysical projects, proposing and developing studies to enhance the information of frontier basins and to generate new exploratory opportunities. In his last 2 years in the ANH Victor collaborated in Unconventional resources, where he developed his interests for CSG. In the last two years, Victor has been studying a Master research program (MPhil) at The University of Queensland, which findings will help in the understanding of the potential of Colombian Unconventional resources. His research interests focus on CSG, Geostatistics, Modelling and Geochemistry.



This event will be hosted at our usual venue in compliance with the Brisbane Hilton COVID Safe Plan.

Measures that we will be taking on the day to ensure your safety :

•    Please adhere to social distancing rules (1.5m apart) at all times.
•    On arrival at the Victoria Room you will be asked to check-in using a QR scan code. You can do this using your mobile phone. If you do not have a QR code compatible mobile phone, a PESA Qld Committee Member will check-in on your behalf.
•    No stand up or mingling before the event. Please proceed directly to a table and be seated. Welcome drinks will be served and consumed seated at the table.
•    Hand sanitiser will be available throughout the room and in the centre of each table.
•    Numbers will be limited to one person per 4 square meters with a maximum of 6 people per table.
•    There will be adequate distancing between tables.
•    Seating will be provided for talk only guests at the back of the room and will be adequately spaced to comply with social distancing rules.
•    Please do not leave your table unless attending the bathroom.
•    On completion of the event please check-out and leave the venue in a timely manner.

For the safety of all attendees and Hilton Hotel guests, PESA Queensland ask that you do not attend this event if:
-in the last fourteen days you have been unwell or have been in contact with a known or suspected case of COVID-19
-in the last fourteen days you have travelled to and returned from interstate or overseas

If you are showing signs of being unwell, having any respiratory symptoms (even mild) or showing signs of fever, you will be requested to return home and seek medical attention.



This month, PESA QLD is happy to welcome Mr Pascal Asmussen from the Sustainable Minerals Institute to present a technical luncheon entitled “Multimethod sediment provenance study of the Adavale and Darling basins: Integrating provenance tools in a spatiotemporal context.”

We will also hear from our PESA Scholarship Holder Mr Victor M Sepulveda presenting “Stable Isotope and Molecular Composition of Coalbed Production Gas and Waters of a Coalbed Methane Field in the Cesar Rancheria Basin, Colombia: Implications for Gas Origins and Distribution.”


The Technical Lunch will be held at the Brisbane Hilton Hotel, in the Victoria Room with access from the Hilton Main Foyer on level 6.
For detailed directions, see explanation below.

Please note the Early Bird ticket pricing cutoff times described below.

Presentation Abstract:

Multimethod sediment provenance study of the Adavale and Darling basins: Integrating provenance tools in a spatiotemporal context 

The Devonian Adavale and Darling basins are amongst the oldest sedimentary basins in the Tasmanides and represent a valuable research area to learn about the early geological history of the Thomson and Lachlan orogens. The relationship of the coeval basins is debated, suggesting broad similarities in depositional environments. In this study we integrate results from sandstone petrography, detrital zircon/rutile U-Pb geochronology to investigate the sediment provenance of the two. The data is discussed in a spatial and temporal context for the Adavale Basin and ultimately correlated with a combination of legacy and newly acquired detrital zircon/rutile U-Pb geochronology data from the Darling Basin. Both basins record similar provenance signals in terms of reworking of their respective hinterlands and relatively distal syn-depositional volcanism. The correlation of sediment provenance proxies, however, suggest that the Adavale and Darling basins were not connected during the Devonian.

This talk presents a subset of Pascal PhD studies and will highlight some novel data interrogation approaches to provenance studies integrating analytical and data science methods with traditional geological methods.

This will be preceded by a short presentation from the 2019 PESA Qld scholarship holder.

Stable Isotope and Molecular Composition of Coalbed Production Gas and Waters of a Coalbed Methane Field in the Cesar Rancheria Basin, Colombia: Implications for Gas Origins and Distribution

Cesar Rancheria Basin, one of the most prolific coal basins in Colombia has been tested for the last decade for unconventional coal seam gas CSG resources. The Sub-basin is subdivided into domains or compartments by series of thrusts. Gas contents and saturation vary between these domains. The compilation and analysis of coal rank data suggest that the rank of the coal varies between the compartments and depths. Isotopic analysis of the production gas and waters suggest a primary biogenic origin, contrary to the expectations of a thermogenic and microbial gas mix, at least in the shallow reservoirs.
