SA Branch host Henry Posamentier

Posted by

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.

SA/NT Branch Winter Warmer

Posted by

Not to be outdone by WA Branch, SA/NT Branch held their Winter Warmer on 7 August at Prohibition Gin Distillery, in Adelaide’s CBD. Over 40 hearty souls braved the cold evening in the distillery’s tin shed to sample 3 different gins (Classic, Blood Orange & Field Blend Shiraz); cleansing ales were available for purchase as well. The proprietor  provided detailed information on each of the gins (and ales) and gave us suggested drinking instructions. Unsurprisingly, most members did not require much of the latter. Pizzas a-plenty were provided to sop up the drink.

SA Branch June technical lunch

Posted by

The June technical lunch meeting of PESA SA Branch featured a fascinating presentation by  Dr Markus Häring (Consultant) on “The impact of triggered earthquakes of the Basel geothermal project 2006 on Engineered Geothermal Systems.”  Dr Häring was the Director of Geothermal Explorers and faced the criminal court of Basel City for causing material damage and flooding as a result of the induced seismicity - fortunately he was cleared of the charge.  Dr Häring will present an expanded version of this talk as a PESA Webinar later this year, so stay tuned.

The presentation is timely as there's been a resurgence in geothermal energy exploration in SA with new licences granted over the last few years to test new exploration concepts and technologies.

2025 SA HICCUP Tournament Summary

Posted by

The HICCUP cricket tournament, sponsored by PESA (Petroleum Exploration Society of Australia), has a rich 45-year history as a social tradition in the South Australian Oil & Gas industry, bringing together government, private, and academic personnel.

HICCUP is appealing due to the relaxed environment of playing a social, yet competitive, format of cricket after work in the Adelaide parklands while providing a fantastic avenue for strengthening working relationships between colleagues and peers from opposition teams.

Teams play with 12 players, and everyone gets to have a bowl and a hit in the 20 over format.

Field Trip: From a Carbonate Ramp to Siliciclastic Fluvio-Deltaics in a Tectonically Active Delamerian Cambrian rift. Seismic-Scale Depositional Systems in Outcrop Field Trip

Posted by

On a glorious spring weekend members and friends of the SA/NT Branch were able to participate in a self-drive field trip led by Rhodri Johns and Elinor Alexander.  This was a joint field trip with PESA SA/NT, GSA and the Field Geology Club of Adelaide.  It was an opportunity to investigate the Cambrian evolution of South Australia through spectacular seismic scale coastal exposures along the west coast of the Fleurieu peninsula.  

Although a two-day field trip participants had the option of participating in either or both days.

The first day was spent examining the carbonate ramp deposits of the Sellick Hill Formation and the clastic turbidites of the Carrickalinga Head Formation at Myponga and Carrickalinga.

MONTHLY MEETINGS

In late September, PESA SA/NT was treated to an enthralling discussion from Glenn Toogood (entX) and Tim Rady (Geomorph Energy) discussing the salt cavern storage potential of the Polda Basin.  This basin is a Neoproterozoic to Jurassic sedimentary basin, extending from the Great Australian Bight to the central Eyre Peninsula, South Australia. It has previously been explored for petroleum, uranium, coal, groundwater, base metals, potash and diamonds.
