Hello and welcome to The Carbon Loop — a newsletter by the CCUSNA dedicated to highlighting the Australian carbon capture, utilisation and storage industry

CCUSNA Goes East ..

Three of us from the CCUSNA Committee packed our scarves (and light emotional baggage) and headed to Melbourne earlier this month for the Carbon Capture APAC Summit. We appeared on more than one panel (read: two) and did our best to champion the CCUS cause without tipping over into cringe.

Highlight of the event, at least for me, was Brett Woods, CEO of Beach Energy, who used a solid chunk of his time to praise Gorgon — a competing CCS project. He

The Renaissance Tour: A revival of frontier basins with data-driven exploration.

By Lauren Found, Searcher.

Lauren Found of Searcher Seismic took us on a global magical mystery tour from the offshore Papuan Basin to the Scotia Basin offshore Canada on the northern Atlantic margin and the Orange Basin, offshore Namibia with its conjugate the Pelotas Basin offshore Brazil and showed us new insights from new data and interpretation in these basins that make them look more interesting than previously thought.

Lauren showed a new crustal model for the Gulf of Papua interpreted from long offset 2D seismic data suggesting the presence of new and previously overlooked depocenters and the possibility of the contin­uation of the oil provinces that are prolific in the onshore.

WA Winter Warmer event (includes photo gallery)

On 18th July, PESA-WA held their “Winter Warmer” networking event at The Globe Lounge Bar in Perth CBD, which this year featured a Jazz Quartet. Sophie Kerr and her band (WAPPA and ex-WAPPA students) played fantastic mellow as well as lively jazz tunes. The event was really well attended (62 people). It was a great opportunity to socialise with colleagues, friends and new members, particularly on a cold Winter’s evening. There was an open bar until 10pm, with fantastic food platters and raffle prizes.

The Bedout Sub-basin, part of the Roebuck Basin on Western Australia’s North West Shelf, has drawn interest since hydrocarbon discoveries at Roc, Dorado and Pavo. Despite these successes, the region remains underexplored.

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.

PESA VIC/TAS Branch welcome a new President

Posted by

Above image: The last time that Nick was in Tasmania (2017). Caution, some changes may have occurred since then!

After 10 years of sterling service, Tim O’Brien is stepping down from the branch presidency and Nick Hoffman is taking up the role. We would like to thank Tim for his dedication to the role through thick and thin, whilst also toiling hard against the Victorian government bureaucracy over onshore gas. Perhaps the tide is finally turning there as gas shortages creep ever closer to the east coast energy market?

Summary by Dr Fiona Burns

On  Tuesday 10th June, DEMIRES (in collaboration with PESA WA and  CCUSNA) organised a core workshop entitled  “Perth Basin from a CCS Perspective” which was  presented by Julie Cass and Dr Arthur Mory. We spent a day at the Perth Core Library considering how our collection of cores helps us to understand CCS targets in the Perth Basin. We also delved into the importance of characterising seals, the influence of reservoir heterogeneity vs homogeneity and how diagenesis impacts pore geometry.
