PESA SA/NT Branch November 2025 Technical Luncheon

08/12/2025 Posted by Rachel

Anthony Western of Santos gave the SA/NT Branch a very interesting and informative talk on“Moomba CCS – delivering a world leading CO 2 storage project”.

The Moomba Carbon Capture and Storage project is a large-scale CCS project at the MoombaGas Plant in the Cooper Basin, South Australia. New facilities were constructed to capture,dehydrate, transport and permanently store CO 2 emissions that were previously vented toatmosphere, and depleted gas fields were selected as the initial storage reservoirs. Five newinjection wells were drilled, and existing wells were re-purposed as monitoring wells to enable theMonitoring and Verification (M&V) plan including environmental assurance monitoring.

PESA Queensland Christmas Party

04/12/2025 Posted by Rachel

About 60 people gathered to celebrate the festive season and the year that was 2025 at the Stamford Plaza in Brisbane on Friday 28 November.

Thanks to our sponsors for the day, Velseis, InGauge, RealTime Seismic, Terrex (the lucky door prizes), ERC (the trivia quiz), and Comet Ridge (the oil price guess). Without this support the event would not be the same.

There were plenty of prizes and winners on the day.

The trivia quiz was ultimately won by Sam McDermott, after a tie between Sam and Peter Crosdale, who each scored 15 points from a possible 20.

Henry Posamentier touches down in WA

04/12/2025 Posted by Rachel

Henry Posamentier presented a 2-day course in Perth on 6-7th November at PanPacific. His workshop delivered a masterclass on seismic stratigraphy and seismicgeomorphology and was based on Henry’s over 50 years of global experience andpioneering work in developing the contemporary approach to sequence stratigraphicanalyses. This attracted 18 attendees.

He also spoke at Faradays in Perth on evening of 6 th November.

PESA Queensland welcome Henry Posamentier

24/11/2025 Posted by Rachel

PESA Queensland were delighted to host 40 PESA and ASEG members for an evening lecture from famed geologist Henry W. Posamentier.

2025 PESA Distinguished lecturer Henry Posamentier is a well known name in the disciplines of seismic and sequence stratigraphy. Through his career, he has worked for Chevron, Anadarko, Arco and Exxon as well as serving as an AAPG Distinguished lecturer around the world. Thanks to sponsors Santos for bringing him to Australia so PESA members could enjoy his presentation focused on deep water deposits of the Bay of Bengal and the Norwegian Sea.

SA Branch host Henry Posamentier

10/11/2025 Posted by Rachel

The Petroleum Exploration Society of Australia (SA/NT) branch hosted Henry Posamentier on the 3 and 4 November 2025 when he presented both a 2-day workshop and a luncheon meeting. His workshop and luncheon presentation delivered a masterclass on seismic stratigraphy and seismic geomorphology and was based on Henry’s over 50 years of global experience and pioneering work in developing the contemporary approach to sequence stratigraphic analyses, integrating sedimentology, stratigraphy, and depositional systems analysis.

The workshop attracted 26 registered attendees and the lunch presentation even more with an additional 24 registered.

PESA QLD Student & Early Career Meets Industry Night

10/11/2025 Posted by Rachel

In October, the PESA-QLD joined with peer societies to host their annual Student & Early Career Meets Industry Night.

The longstanding event is a combined outreach effort to connect student and early career geoscientists to the broader technical community. The formula for these successful events is long tried and true: a networking bingo to break down barriers, stellar mineral prizes to encourage competition through engagement, and a dedicated space for students to ask industry professionals their burning questions.

PESA presence was strong and varied, demonstrating the breadth of careers available in Oil & Gas.

This is key in Brisbane, where the job market is dominated by the mining sector and there is no local Petroleum School to raise our industry's profile.

PESA WA Technical talk and Core Workshop with Brian Willis

PESA WA October Technical Evening Talk —

By Matt Fittall

A core group of PESA geoscientists gathered at The Globe on the evening of October 2nd to learn about the impact of new numerical modelling of deposition in wave influenced deltas in the interpretation of deltaic sequences and their facies distributions. Dr Willis and his co-workers showed how this work challenges the paradigm of a prograding equilibrium shoreface profile and a gradual upward- coarsening facies progression with a sharp-based shoreface succession generated by a relative sea-level fall.

In his presentation Brian Willis demonstrated that differences in...
