WA evening talk – US Double act on fluvial systems

Posted by

A good crowd again assembled for Perth PESA evening talk on August 14, a double act on fluvial systems by John Holbrook (Texas Christian University) on the “Back-water Effect” on fluvial systems and Steve Hasiotis (University of Kansas) on the Neoichnology of the De Grey ephemeral river delta, Northwest WA

John Holbrook’s talk on the backwater effect provided an interesting discussion on fluvial architecture styles and an emerging tool and a work flow for predicting reservoir architecture, dimensions, volumes and heterogeneity in fluvial systems. 

Steve Hasiotis described the diagnostic patterns of plant and animal traces (and diversity),...

ADNOC Eyes Santos: A High-Stakes Bid That Could Reshape the Asia-Pac LNG Landscape

Posted by

In a bold strategic maneuver, Abu Dhabi’s state-owned oil giant, ADNOC—via its international arm XRG, in partnership with ADQ and global private equity firm Carlyle—is pursuing the acquisition of Australia’s Santos Ltd. The A$30 billion (US$18.7–19 billion) all-cash bid, unveiled in mid-June 2025, emerges as the largest takeover proposal in Australian corporate history.

This acquisition aligns with ADNOC’s ambitious goal: becoming a top-five global player in LNG by 2035. Santos’ assets—including Darwin and Barossa LNG projects, a stake in PNG LNG, and significant exploration acreage like Beetaloo Basin—provide essential footholds in the Asia-Pacific region

ADNOC has made...

GA releases plans for the 1st 10 years of “Resourcing Australia’s Prosperity” initiative

Posted by

Geoscience Australia have showcased their planned projects for the first 10 years (2024-2034) of the Resourcing Australia’s Prosperity initiative in an online webinar, where the Minister for Resources and Minister for Northern Australia the Hon. Madeleine King MP announced the location of the third deep dive project in the Georgetown-Julia Creek region, Queensland.

The 35-year $3.4 billion investment by the Australian Government was established to accelerate the discovery and development of the resources needed to support Australia’s net zero transition and resources management through 4 interrelated components.

Held on Tuesday 26 August 2025, the webinar went into detail about what to expect from the wide range of projects over the next 10 years and how they fit under the 4 components.

A Summary of GSWA Stratigraphic drilling in sedimentary basins, Western Australia

The Geological Survey of Western Australia (GSWA) routinely acquires new pre-competitive geoscience data to encourage exploration within Western Australia. Drilling in underexplored regions by this organisation aims to update stratigraphic and age relationships, and the prospectivity for many commodities. In Neoproterozoic–Phanerozoic sedimentary basins such drilling can reveal the existence of reservoir, seal and hydrocarbon source rocks, and can provide geothermal data to aid prospectivity assessments for petroleum (oil, hydrocarbon gas, helium, and hydrogen), coal, geothermal energy and CO2 sequestration.

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

Posted by

by Karyna Rodriguez, Neil Hodgson & Lauren Found

Presented at the Petroleum Exploration Society of Australia (WA Branch) Lunch Series, June 2025

Full article available here

As the energy exploration landscape evolves, so too does the thinking around the basins being investigated. Advancing seismic acquisition and processing technologies in the last decade have allowed for explorers to take a fresh look on frontier and previously discarded basins, with the shifts in thinking and interpretation yielding billions of barrels of results.

In this world tour, four deep-water basins are investigated, including the Papuan Basin of Papua New Guinea (PNG), the Scotian Basin of Canada, the Namibian-South African Orange Basin and its Brazilian conjugate margin in the Pelotas Basin.

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.
