PESA WA invites you to our Christmas technical luncheon on Thursday 15th December: “HISTORY OF ENERGY TRANSITION: What have the Romans (Geoscientists) every done for us?” Presented by Mark Lisk - Chief Geologist Ascendience Geoscience. Mark will deliver a light-hearted whimsical review of the ongoing human energy transition, reflecting on the role played by geoscientists (Romans).

Presented by Julie Cass, GSWA. The Ordovician interval cored in Olympic 1 is one of the best-documented cored intervals of the Nambeet Formation in the Canning Basin. Consequently, the Geological Survey of Western Australia (GSWA) entered into a collaborative core analysis agreement with the EP473 Joint Venture to acquire a suite of core plugs for stratigraphic and petroleum system testing and CO2 geosequestration evaluation.
This presentation offers an integrated interpretation of petrophysical and petrographic data acquired at Olympic 1, assessing reservoir quality in the Ordovician and the impact of acoustic properties on seismic prospecting at the Meda unconformity. Volume of clay, porosity and saturation have been calculated from wireline logs to assist in the petrophysical evaluation and for comparison with x-ray diffraction, routine and special core analysis measurements.

PESA WA invites you to a 1 day workshop on Friday 23rd February, “Salt Tectonics in Australian Sedimentary Basins”, presented by instructor Chris Elders. Interest in salt deposits in sedimentary basins has increased dramatically in recent years because of its potential role as a seal for natural hydrogen and helium accumulations, and as a site for the storage hydrogen and other gases. Although salt is present in a number of Australian basins, there are relatively few studies that document the evolution of salt structures in the context of wider research that has developed rapidly over the past 20 years. In this workshop we will examine current thinking on the evolution of salt structures and apply these concepts to examples of salt structures from the Petrel, Vulcan, Canning, Officer and Amadeus basins. Participants are encouraged to bring examples of their own favourite salt structures for part of the discussion.

On Friday 24 February (1.00 pm to 4.00 pm) a special session of the Sedimentology and Stratigraphy Interest Group at the Perth Core Library, 37 Harris St, Carlisle, led by Vincent Crombez, Fionna McNee and Chris Elders, will examine cores from mineral and petroleum wells in the Canning and Office basins that have penetrated thick salt sequences. This will provide us with the opportunity to investigate the composition and deformational fabrics in mobile and non-mobile salt, as well as the underlying and overlying stratigraphic successions. As is tradition, the SSIG workshop will be followed by drinks at 4.00 pm at the Balmoral Hotel, Victoria Park.

Wadjemup (Rottnest) Field Trip - Corals, calcareous aeolianites & Quokkas – by bike. A c. 17 km cycling tour of the island, taking in sights at Salmon Point, Fairbridge Bluff, the Lighthouse, Mt Herschell Quarry, and Geordie Bay will enable us to examine these different features. We will follow a circular route, with a scenic stop to eat our packed lunches (please bring your own) and return back to the settlement in time for a beer in the pub before the ferry returns to Perth.

Presented by Jeff Goodall, HyTerra. This presentation demonstrates how the targeted methodology for natural hydrogen exploration has moved from surface circular features to a more expansive subsurface geological model which supports hydrogen generation on a regional scale in localized prospective areas.
The deliberate targeting of natural hydrogen resources in the Central Midwest of the USA is underway with a rapid ramp-up of exploration activity, including drilling and well testing by multiple companies. These data will help inform and refine our understanding of natural hydrogen system/s both in the Central Midwest and in other prospective locations globally.
