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.
PESA Branch Activities


PESA Qld Technical Talk: Exploring for Hydrogen
The Queensland branch July meeting returned to the Port Office Hotel for an interesting talk on Hydrogen exploration from Dr Josh Whitcombe, VP of Development and Operations at HyTerra.
Josh took time to introduce the audience to the different types of hydrogen and where they might be found. He then dived into more detail about the exploration and appraisal work Hyterra are doing at their Nemaha Project in Kansas, USA.
Nemaha is located between Kansas City and Wichita in the centre of a major industrial and manufacturing hub.

SA Branch June technical lunch
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
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?

PESA WA Core workshop in collaboration with CCUSNA
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.

WA Lunch talk – all about borehole images
What you should know about borehole images but were afraid to ask…..Forty years of hard-won lessons’ By Lawrence Bourke
Lawrence Bourke of Task Fronterra Geoscience, one of the founders of image log interpretation, took us on a trip down memory lane, back to the embryonic beginnings of image logs with the with the original 8 button high resolution dipmeter of 40 years ago through the revolution (for geologists) of the high-resolution FMS and FMI micro-resistivity devices in the late 1980s and early 1990s at the PESA WA April technical luncheon.
