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 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 hold joint talk with SPE on CCS topics
Summary by Dr Fiona Burns
On Thursday evening, 15th May PESA and SPE held a joint evening event at the ParmeliaHotel. The key focus of the presentations were projects and insights from across Australiaon the topic of CCS, with three separate speakers invited.
Robert Root’s talk (Chevron Australia) was entitled “Gorgon Carbon Capture and Storage –Insights and Lessons Learned”. Rob provided a highly informative overview of Gorgon CCSincluding performance to date, system optimization, and key lessons for other CCS projects.

WA Branch held a joint YP networking event with ASEG and SPE
PESA-ASEG-SPE YP Networking Night, held on Friday, 28th March 2025 at The Shoe Bar
The PESA-ASEG-SPE YP Networking Night, held on Friday, 28th March 2025, provided a unique opportunity for young professionals to connect with experienced industry leaders. The event featured three distinguished speakers: Steve Molyneux, a consultant geologist at Hancock Energy, Sam Howman, Director at Howman Seismic Services, and Lina Hartanto, Subsurface Technical Advisory Group Lead at Chevron. Each speaker delivered a candid 5–10-minute career overview, sharing their personal journeys, the highlights and lowlights of their careers, and the valuable lessons learned along the way.

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.

WA evening talk on Basin centred gas accumulations
PESA WA Evening Talk: Thursday March 20th 6:00 pm - 8:00 pm @ The Shoe Bar
“Tight Gas Sand Reservoir Evaluation: Basin-Centred Gas Accumulation (BCGA) & Implications on Production & EUR” by Greg Salter, Core Laboratories
The dark art of sub-capillary equilibrium gas, better known to us as basin centred gas, was introduced to a small but enthusiastic group of geoscientists at Faraday’s in Perth on the evening of 20th March, by Greg Salter (VP Eastern Hemisphere, Core Laboratories, based in KL).

PESA WA Lunchtime talk by Leon Nomore
On 20th February the WA branch lunch was held at the Hilton. The topic was “Natural Hydrogen in Western Australia” by Leon Normore, Geological Survey and Resource Strategy Division, Department of Energy, Mines, Industry Regulation and Safety, Government of Western Australia.
Leon provided an up-to-date summary of recent studies in Australia on hydrogen in natural gas samples in both sedimentary basins and cratonic settings and also discussed multiple abiogenic sources for natural hydrogen.
He summarised GSWA studies of open file data which focused on historical occurrences of hydrogen within the onshore sedimentary basins with petroleum wells the primary data source in Canning Basin, Perth Basin and Southern Carnarvon Basin well.

Mark Bentley visits WA and gives a course and evening talk
On 13th February 2025, Mark Bentley (Langdale Geoscience, UK) delivered a short course to the WA Pesa Branch members on “Good Models: Bad Models – How can we Tell?”. This course was well attended and a summary of this course is provided below.
Mark also delivered a presentation to the WA Pesa Brach on “Modelling for CCS - new tricks for old dogs”. Thirty or so young and ‘old dogs’ enjoyed an engaging, educational and stimulating evening with Mark who presented on the new paradigms required in reservoir modelling for CO2 storage.
